I have moved a Visual Studio 2010 project to another server by copying and pasting the folder contents into another folder on a different server.
My understand was that VS2010 handled this well; when I have done this locally it has never been an issue.
Now I get an error like this:
When I right click and "Reload project", the list of files briefly appears before disappearing again, giving the original error.
Am I doing something wrong?
I experienced the same problem today. Here is what I did and worked for me :
Open the .sln file.
Right click on the project folder and click Reload project.
You will see the projects and folders that you originally had.
You will see .xml publish file . Double click it .. You should be good to go now.
I had this problem today and it took me a while to figure out what was going on.
Your problem is most likely that your solution was originally made with a Visual Studio configuration that contained support for certain project types (such as "Windows Service" or some other exotic project type). The Visual Studio configuration you are using to import your solution does not have that support. In other words,
there is probably nothing wrong with your solution,
there is probably nothing wrong with your project,
there is probably nothing wrong with any of the files (as you mentioned they do display briefly, giving you a second of hope)
Just run the installer on the new Visual Studio and make sure the support is enabled for all the project types you need and try again.
In my case the problem was the .vbproj file had somehow been corrupted so the normal xml code was replaced with a long string of null characters. I noticed this thanks to a file that was generated in the same folder as the project file when I tried to open the project - it was called 'UpgradeLog.htm'. This had an entry saying ' Error on line 1. Expected '<' but found 'null character'.'.. suggests there may have been a recent update to Visual Studio that I hadn't noticed?
Luckily I could use my source control system to revert back to a slightly earlier version - I guess it shows how important it is to have backups!
In my case, I saw similar message (Projected was unloaded) and all I had to do was simply re-launching Visual Studio (2017) in Admin mode and the problem went away. Per one of the above answers, I tried to right-click and selected Reload but got a warning that, due to required access to IIS on the machine, I had to launch VS in Admin mode.
HTH
Found this answer and it worked for me.
Note:Sometimes, the path in File path property is grayed out and you are unable to get to the Browse button. In this case try deleting .suo files. Don’t worry, these files gets recreated when you rebuild the solution / project.

I had the same problem. I fix path to .csproj files in the .sln file with a text editor and now it is all ok.
Open Visual Studio as Administrator
I was working on a class in visual studio 2010 when suddenly my computer crashes. after I restart the computer. I start Visual studio and I find that class to be completely empty.
it contained more than 1000 lines of codes before the class.
is there anyway i can recover that file?
Help please because I don't have another copy of it (Stupid of me)
If you cannot find the source code file, try using Reflector to decompile the most recently built dll you have containing that class. It won't give you your complete source, but at least will give you something to start with.
Note: Reflector is no longer free; if that matters, try dotPeek from JetBrains instead.
Also, look into using a source code control system. This will let you 'commit' versions of your code to a repository, so you'll have a copy in case something like this happens in the future.
Subversion, Git, and Mercurial are popular ones; In my opinion, Subversion would be the easiest to start out with, especially with TortoiseSVN (OS integration) and AnkhSVN (Visual Studio integration). If you don't want to worry about setting up a repository/server, look into a hosted solution, like Beanstalk, which offers Subversion and Git and lets you try it out with a free, limited account.
Good luck - I hope you are able to recover your source!
Something which worked for me was back-up.
BTW I was trying to recover a VS2013 file on a Windows 8 machine.
Try to check in below location in your system.
C:\Users\username\My Documents\Visual Studio \Backup Files\ProjectFolder
I found an original file with original-date.filename.cs name and a recovered-date.filename.cs files.
The original was the one needed.
Deleted the one in project, added the original file and renamed it to file.cs. Tried building and debugging and it gave the expected results.
Also just want to add one more thing...
In my case i had an aspx page with its respective .cs and designer.cs
The .cs file got corrupted and I did build on project, with the designer.cs the project got build successfully and the dll got replaced. And when i tried to recover using reflector everything was in a state no return. :(
So don't build the project if you see any file got corrupted.
in visual studio 2019 I find the file in a files with TMP extension
FileName.cs~xxxxxxxx.TMP
This happened to me a few times as well when Visual Studio was crashed or System was shutdown unexpectedly.You can recover these corrupted file using Recuva. It dose not recover the file every time but in most of the cases it's work perfectly.
Below are the settings which you need to configure before recovery.
Start Recuva. Enter Advanced mode if the Wizard launches.
Click Options.
In the Options dialog box, click the Actions tab.
Click Scan for non-deleted files, and then click OK.
Run the Recuva scan as normal. Non-deleted files are indicated with a green double-circle status icon.
Hopefully, you will find your corrupted file in recovered files as it recover multiple versions for that file.
Very useful question. I got issue of file crash on sudden shutdown of my PC. recovered file using "Recuva"(download link: https://filehippo.com/download_recuva/) software. Scan for non-deleted files was helpful.
I got help from: https://www.samnoble.co.uk/2014/11/30/visual-studio-crashes-and-a-corrupted-cs-file/
Well, that happen recently for me and I did get my file back this way.
1. Find the project DLLs in the bin folder. Example MySolution.dll
2. Download and Install .Net Reflector from https://www.red-gate.com/products/dotnet-development/reflector/trial/thank-you
3. Open the .Net Reflector app and click the open folder icon then move to your bin directory and select MySolution.dll file
4. Then traverse and expand through your namespaces and classes to look into your codes.
5. Have fun!
How to fix "Root element is missing." when doing a Visual Studio (VS) Build?
Any idea what file I should look at in my solution?
Actually, I am getting this error message inside of "Visual Build Pro" when using using the "Make VS 2008" command. This command works just fine when building other solutions (like about 20) and I am not really sure why mine is getting the error.
Any help would be very much appreciated. :)
I am using VS 2008 and Visual Build Pro 6.7.
In my case it was the xxxxxxxxxxxx.vcxproj.user file that was causing the problem; it was blank after a crash. I renamed it and the problem went away.
Make sure any XML file (or any file that would be interpreted as an XML file by visual studio) has a correct XML structure - that is, one root element (with any name, I have use rootElement in my example):
<?xml version="1.0"?>
<rootElement>
...
</rootElement>
You will also get 'root element is missing' when the BOM strikes :). BOM = byte order mark. This is an extra character that gets added to the start of a file when it is saved with the wrong encoding.
This can happen sometimes in Visual Studio when working with XML files. You can either code something to remove it from all your files, or if you know which file it is you can force visual studio to save it with a specific encoding (utf-8 or ascii IIRC).
If you open the file in an editor other than VS (try notepad++), you will see two funny characters before the <? xml declaration.
To fix this in VS, open the file in VS and then depending on the version of VS
File > Advanced Save Options > choose an appropriate encoding
File > Save As > keep the filename, click the drop-down arrow on the right side of the save button to select an encoding
In my case.I was getting missing element error pointing to NuGet.Config file.
At that time it was looking some thing like this
<?xml version="1.0" encoding="utf-8"?>
<settings>
<repositoryPath>Packages</repositoryPath>
</settings>
then I just added configuration tag that actually wraps entire xml. Now working fine for me
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<settings>
<repositoryPath>Packages</repositoryPath>
</settings>
</configuration>
This error is caused by corrupted proj file.
Visual Studio always has backup project file at specific folder.
Please browse to:
C:\Users\<Your user>\Documents\Visual Studio <Vs version>\Backup Files\<your project>
You should see 2 files like this:
Original-May-18-2018-1209PM.<your project>.csproj
Recovered-May-18-2018-1209PM.<your project>.csproj
You only need copy file:
Original-May-18-2018-1209PM.<your project>.csproj
And re-name as
<your project>.csproj
and override at root project folder.
Problem is solved!
My project did not load and gave me a Root Element Missingerror. I just deleted ****.csproj.user file and reloaded it again. The problem was solved this way
In my case, when I opened the .csproj file, it was empty so I went to my previous commit in git and copied the contents of that file and pasted it my current .csproj file. After which I deleted the .csproj.user file, reloaded my project, and everything started working again.
You can also search for the file. Navigate to your project directory with PowerShell and run Get-FileMissingRoot:
function Get-FileMissingRoot {
dir -recurse |
where {
($_ -is [IO.FileInfo]) -and
(#(".xml", ".config") -contains $_.extension)
} |
foreach {
$xml = New-Object Xml.XmlDocument;
$filename = $_.FullName
try {
$xml.Load($filename)
}
catch {
write ("File: " + $filename)
write ($_.Exception.Message)
}
}
}
I had this issue running VS 2017, on build I was getting the error that the 'root element was missing'. What solved it for me was going to Tools > Nuget Package Manager > Package Manager Settings > General > Clear all Nuget Caches. After doing that I ran the build again and it was fixed.
I got same error. showing error Microsoft.Data.Entity could not loaded root element missing. When i delete that file from C:\Windows\Microsoft.NET\Framework\v4.0.30319 and again open my solution my problem was solved. Everything woks fine
In my case, .csproj was changed to encoded format. I did undo changes to csproj in Git(Team explorer) and reloaded the project file. This solved the problem.
In my case, the file C:\Users\xxx\AppData\Local\PreEmptive Solutions\Dotfuscator Professional Edition\4.0\dfusrprf.xml was full of NULL.
I deleted it; it was recreated on the first launch of Dotfuscator, and after that, normality was restored.
This error can sometimes occur when you edit some Project Toolchain settings Atmel Studio 6.1.2730 SP2.
In my case I tried to edit Project Properties > Toolchain > Linker > General settings with 'All Configurations' selected in the Configuration. When I checked or unchecked a setting, a dialog with the error popped up. However, I found that I could make the same edits if I made them to only one build configuration at a time; i.e. with only 'Debug' or 'Release' selected instead of 'All Configurations'.
Interestingly, I later was able to edit the same Linker settings even with 'All Configurations' selected. I don't know what changed in my project that made this possible.
I had Blue Screen while running Visual Studio 2013, when I Restart I intended to run again my project, but I had always this headius Error.

Deleting The Folders with the Temp info Fix this problem.
in my case the Project was a Windows Server, and Basically it Creates a Folder with some Tem info.
the folder was
C:\Users\User_NAME\AppData\Local\NAme_OF_THeProject
inside Exist a Folder with the Name of the Project+ some Generated GUI
Service.ServerHostLoader_Url_u2jn0xkgjf1th0a3i2v03ft15vj4x52i
this is the Folder I deleted and now I can run again the Project.
In my case I upgraded to VS2017 and wanted to build all projects with MSBuild 4 with my build script (which had been using MSBuild 3.5 when we were using VS2015). That MSBuild upgrade appeared fine for the Windows desktop applications but the ones for Windows CE with compact framework would give me this confusing error. Reverting to MSBuild 3.5 for Windows CE projects fixed the issue for me.
I did have the BOM in .csproj files by the way and removed them for all projects in a solution that would not build but that did not help.
In xamarin form project. I deleted
.VS Project folder.
ProjectName.Android.csProj.User
ProjectName.Android.csProj.bak
In my case I received a message like this:
See this picture
I just commented the snipped code below in the project file (.csproj) and the problem was fixed.
<Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" />
In my case xxxx.pubxml.user was not loaded when tried to publish the application. I deleted the file and restart the Visual studio then created a new profile to publish it, problem is solved and published successfully.
Hey, I have the same issue on Mac working on a Cocoa C# solution.
(But I solved it !)
It always say that the root element is missing so it cannot load my C# project file.
I have the 2017 Visual Studio Mac Community Edition.
I finally managed to find a solution after several hours (painful!).
My solution is because the frameworks related to the Visual Studio are old or broken.
I found this because I tried to create a new Mac solution by Cocoa and it said "failed to save the solution". Then, I tried to create an Android Solution and it is working fine.
Go to your "Finder" and "Go" -> "Go to a Folder" then go to the "Library/Frameworks". I have deleted mono.framework and frameworks related to Xamarin because I believe these Xamarin frameworks are broken.
Then, uninstalled the Visual Studio and reinstalled it.
Now everything works fine!
In my case, I just renamed the .csproj.user and restart the visual studio and opened the project. It automatically created another .csproj.user file and the solution worked fine for me.
Ho i simply solved this issue by going to source control explorer and selected the issue project, right clicked and selected the option Get Specific Version under Advanced menu. And then selected Type as Latest Version and ticked following two check boxes and clicked Get button. Then i refreshed the solution and my project came back to live and problem gone. Please note that This may overwrite your local projects so your current changes may lose. So if you dont have any issues with your local copy then you can try this. Hope it helps
I got this issue on a Web API project. Finally figured out that it was in my "///" method comments. I have these comments set to auto-generate documentation for the API methods. Something in my comments made it go crazy. I deleted all the carriage returns, special characters, etc. Not really sure which thing it didn't like, but it worked.
In my case the RDLC files work with resource files (.resx), I had this error because I hadn't created the correspondent resx file for my rdlc report.
My solution was add the file .resx inside the App_LocalResources in this way:
\rep
\rep\myreport.rdlc
\rep\App_LocalResources\myreport.rdlc.resx
I had a few massive VS2015 Community crashes.
Delete all the .csproj.user files
which were full of null characters, and also these
C:\Users\UserName\AppData\Local\Temp\
.NETFramework,Version=v4.0.AssemblyAttributes.cs
.NETFramework,Version=v4.5.AssemblyAttributes.cs
.NETFramework,Version=v4.5.2.AssemblyAttributes.cs
In my case, I got this error because of an empty packages.config file.
This caused the NUGET package manager to fail and show the error Root element is missing.
The resolution was to copy over elements from another non-empty file and then change it according to the needs.
Example (packages.config):
<?xml version="1.0" encoding="utf-8"?>
<packages>
<package id="Microsoft.AspNet.Web.Optimization" version="1.1.3" targetFramework="net451"/>
<package id="Newtonsoft.Json" version="5.0.4" targetFramework="net451"/>
</packages>
In my case, i was using vs 2010 with crystal report. Innerexception revealed root element is missing error. Go to directory like C:\Users\sam\AppData\Local\dssms\dssms.vshost.exe_Url_uy5is55gioxym5avqidulehrfjbdsn13\1.0.0.0 which is given in the innermessage and make sure user.config is proper XML (mine was blank for some reason).
Deleting the .user file is exactly what fixed the problem for me. Lightning strike near the office shut my PC down and corrupted my .user file and project wouldn't load. I opened the file in Notepad++ and the "spaces" turned out to be [NULL] characters. Deleted the .user file and the file loaded!

I had the same problem in a Xamarin Forms project. iOS project was unavailable and I couldn't reload the project. I was looking for a solution that doesn't need uninstalling anything.
The answer I got from this blog:
https://dev.to/codeprototype/xamarin-form-application-failed-to-load-android-project-root-element-missing--27o0
So without uninstalling anything, you could delete the .csproj.user file (or rename it) so Visual Studio will create the file again. Worked for me twice.
In my case the problem occurred due to closing my PC while visual studio were remain open, so in result csproj.user file saved empty. Thankfully i have already backup, so i just copied all xml from csproj.user and paste in my affected project csproj.user file ,so it worked perfectly.
This file just contain building device info and some more.
No one of these solutions fixed my problem.
In my case, I finished my work and I shut down my computer. The day after I wasn't able to compile my project. I tried some of these solutions and I realized all my projects weren't work.
To Fix it, I reinstall .net core Framework.
Visual Studio 2017
I'm working on my first project in Visual Studio and I haven't used Windows much since '05, so please bear with me.
I've got my project open in Visual Studio 2008, and I'm trying to open a particular file for editing, but I get an error that says
"c:\path\to\file
Cannot open file.
I've verified that the file exists, and I can open it from Windows Explorer, but nothing from inside Visual Studio, any ideas?
I'm not familiar with Visual Studio, so my terminology might be incorrect.
The file appears in the tree in the Visual Studio Explorer pane, so I double clicked it, and got the error. The error said nothing more than the file path: Cannot open file.
How can I check permissions/ACLs in Windows? I assumed that since I could open it in Windows Explorer, I would be able to open it in Visual Studio.
And it's a .cpp file.
You may want to right-click on the file in the tree, and delete it from the project.
Then, add back an existing item.
Hopefully that will fix the problem.
Though I'm not familiar with this specifically, if you just want to move forward, I'd recommend creating a new project type and just adding all the existing files to it. Should be quicker and easier than diagnosing what could be many issues.
Other things to check: encoding type of the project file, permissions/ACLs (can you open that actual file from an unelevated VS prompt, for instance), etc.
Additionnaly to the other answers, I found out that this problem may arrise if the target .Net framework version specified in the project file isn't installed.
This seems to prevent visual studio from opening all the files contained in the project, and showing the "Unable to open file " message.
Correcting the version (in the csproj file or in the settings), saving and reloading the project fixes the problem.
I had same problem, my project were build on (.Net 4.5), which I uninstalled on my PC and replaced by (.Net 4.8), so just replacing project's target framework to the one which is installed "in my case (.Net 4.8)" should fix it.
I recently migrated a VSS database to TFS 2008. Using Source Control Explorer, I got the latest version of a solution with 12 projects.
When I opened the solution in VS 2005, two of the projects were not found. I am not sure why these two projects were not found, but thought it easiest to just delete and re-add them to the solution.
When I do this, VS gives me a "A project with that name is already open in the solution." The project doesn't appear in solution explorer, and is not listed in the .sln file.
Any ideas?
I had this problem and I was able to solve it using the following steps:
Remove the project from the solution.
restart visual studio.
add the project to the solution as an existing project.
I had the same message... Seems like it comes from (.csproj) project file. Under first propertygroup there is a section named
<ProjectTypeGuids>...</ProjectTypeGuids>
which generally tells Visual Studio to handle that project in some specific way. Some Guids can be found here.
First make a backup copy of that file. Then removing that section can help you open the project as usual project. As it seems that the Visual Studio thinks that the project is not the type that is specified in the ProjectTypeGuids.
This did it for me:
remove the section <ProjectTypeGuids>...</ProjectTypeGuids> in each project
reopen each project, then save to overwrite the existing project file, finally exit
reopen the solution file
pray (optional)
If anyone uses AnkhSVN instead of TFS, it's also possible, that the .sln-file need the following lines:
GlobalSection(SubversionScc) = preSolution
Svn-Managed = True
Manager = AnkhSVN - Subversion Support for Visual Studio
EndGlobalSection
in the "Global" section.
Before anyone tries tempering with their solution- and project files, figure if you may have project dependencies outside the solution, such as IIS - and you forgot to start Visual Studio in Administrator-mode
For me, the project not loaded was because it was configured to use IIS on the local machine and I needed to start Visual Studio as an Administrator.
I have to say that removing the section <ProjectTypeGuids>...</ProjectTypeGuids> could create some problems.
In fact, such a section defines the type of the project and, if removed, could disable some features.
For example, if your project was originally defined as Smart Device (C#), after removing the aforementioned section the on-device debug may not working properly.
Delete .suo file. Build solution. Add Projects.
Unfortunately I don't know the why behind the obtuse error message, I can merely provide what steps I took to get it to go away.
In my case, I had reconfigured my local IIS (<UseIIS> not <UseIISExpress>) and it was no longer hosting the URL that was in the csproj <IISUrl> field.
Editing the .csproj file in another editor and changing that field to the new URL, followed by closing and opening the solution in VS resolved the issue.
I would try hand editing the project/solution files, they are text and pretty easy to read. You can edit the file in notepad. To open up the file as text in visual studio you need to first close the solution. Then do file->open and select the sln file, but instead of hitting the open button, press on the right side where there is an arrow and select open with.. from there you can select source code editor (text).
Somehow VS 2022 doesn't create a virtual directory anymore. I had to manually create the website in IIS
I had the same problem when i migrated a website to a web app project.
Unload the web app.
Add the existing website.
Reload the web app.
The following worked for me when I moved a project running vs2010 to another laptop.
I removed exactly the following and it worked:
<ProjecctType>Guid of sorts</ProjectType>
<SccProjectName>Svn</SccProjectName>
<SccLocalPath>Svn</SccLocalPath>
<SccAuxPath>Svn</SccAuxPath>
<SccProvider>SubversionScc</SccProvider>
For those looking for this while dealing with VSTO projects...
Be sure to have the Office Tools for Visual Studio installed in your machine before opening the project.
I solved it by changing Windows' regional settings. Instead of "English (Europe)", I used "English (United States)". Others have reported similar behaviors with changing for example from "Russian (Ukraine)" to "Russian (Russia)", etc.

In my case it was corrupted vbproj file. First line was missing:
<?xml version="1.0" encoding="utf-8"?>
After adding this line I had to close the solution, delete .vs folder and open again.
I got it in Visual Studio 2022 version 17.4.4.
You may also see:
Error HRESULT E_FAIL has been returned from a call to a COM
component.
when you try to reload your project.
One way to load the project (and deal with IIS directories later) is to edit the .csproj file and set UseIISExpress to true.
Replace:
<UseIISExpress>false</UseIISExpress>
with
<UseIISExpress>true</UseIISExpress>
Then you need to close your solution and open it again and the project should load.
I encountered this issue with web application projects.
When I tried to reload the projects, the VS2022 output said something like :
"The project is configured to use IIS. Unable to find the server
'{site_url}' on the local computer. Ensure that the local IIS is
configured to handle secure communications."
Which is pretty clear. Indeed, in my case, this was caused by my website https binding that just vanished for no reason (it happened to me several times, looks like a bug with Windows 11 & IIS 10). Things got fixed when I got my https binding back (projects could load norammly).
In VS 2022 to open a legacy web project I had to:
Remove from Solution
Change framework version from 4.6.x to <TargetFrameworkVersion>v4.7.2</TargetFrameworkVersion> in from csproj
Remove <OutputType>Library</OutputType> from csproj
Close Solution and open it again (!!!)
Add project to the sln again.
