I have been working on this little mobile app for android using Xamarin in Visual Studio 2017.
When opening the solution with the laptop that I used to develop the app works like a charm. Then I zip the entire folder over the solution.
../myFolder/
app1/ //here is all the code
app1.sln //solution file
myFolder.zip
Transfer the zip file to other laptop/PC through usb, email and online repository, even extensions like rar, 7zp and tar. I simply can not load the solution from other Visual Studio but the one where I created/developed the application originally.
Hours passing with this screen then VS is not responding and after that, it simply crashes/closes with no error message.
In the other hand, I can open any solution created from any other PC in my laptop without issues. After saving, I haven't found the pattern yet, but some solutions can't be opened from the original PC which creates them nor others.
You may be using an older version of Visual Studio on the PC you've facing the issue. I've faced that too.
It was a known bug (reported here and here) already fixed on newer versions.
The workaround is to close VS, delete the folder vs created in the same directory of your solution and try to reopen it.
To avoid other problems on compiling or running your app after that, I recommend you also to delete all bin and obj folders from your project's folders, clean and rebuild the solution.
It's safer keep all your development environments updated in software wise to avoid this kind of trouble.
I hope it helps.
I created an Asp.Net Core 2.0 WebApi application using Visual Studio 2017 version 15.3.3. Whenever I add, edit or delete files from the Solution Explorer, VS freezes for an indeterminate time (2 - 120 seconds), before becoming responsive again.
I have followed all the suggestions from https://developercommunity.visualstudio.com/content/problem/30723/visual-studio-2017-too-slow-for-use.html, but with no success.
I was hoping someone had a solution to this problem, so that I do not have to send a trace to the Visual Studio Team.
It should be noted that I have ReSharper Ultimate and Web Essentials installed, but the problem persisted after disabling them both.
I had the same issue as you today and it was driving me crazy.
Eventually I did a dotnet restore in a command prompt in the web application directory. This solved the long freezes for me. Before the 'restore' adding/removing files took one minute or more, now it only takes 1 second. It could still be better but it is workable now.
Update: the web project I work on has two node_modules folders: one in the project root and one in a subdirectory. When I delete the one in the subfolder the IDE becomes even more responsive. So it looks seems that a Visual Studio 2017 ASP.NET Core web project gets a performance hit when there are a lot of files/subdirectories in the project files. And 'node_modules' is - alas - a directory that grows very fast in size...
Update 2: You can exclude extra folders by adding the <DefaultItemExcludes> property to the .csproj file, like <DefaultItemExcludes>$(DefaultItemExcludes);ClientLib\node_modules\**</DefaultItemExcludes>. This solved it for me.
I took the advice of David Urting and ran dotnet restore to no avail.
My solution also has a client folder containing an angular 4 application, with another node_modules folder.
I removed the client application from WebApApi solution and moving it into the same folder as the .sln file, which is where my git repository is.
When I run ng build --prod (angular cli), I move the distribution files into the www folder of the web application.
The freezing/not responding has ceased.
It should be noted that I removed the node_module folders from the solution also, but this did not help either.
So I have a handful of Visual Studio projects that I need to move to another computer. Is it as simple as a copy and paste or will that mess something up? Both machines will have the same version of Visual Studio installed, so that shouldn't be an issue.
Is there an export function that I've overlooked?
If the Visual Studio version is the same, you can just copy the project folder.
Till the time you are moving your solution file and associated files you should be good.
In case you are using any source control update your solution from there.
Hope you have the same VS version and any addon frameworks you have
You can directly copy the project to the projects folder. This worked perfectly for Visual C++ projects for me (and also some other projects). But when I copied my Cordova App from one PC to the other (Both had Visual Studio 2015), I wasn't able to open the project. Whenever I tried to open the project, trying both the ways - directly from the Project file and the open option in Visual Studio, it at first opened but when I tried to open a file, it just got hung and didn't respond.
This problem may occur because Cordova apps have some configuration files that might be different for different PCs. I am not sure that this is the reason for the problem.
A solution that I used was that I created a new Project and copied the files to the project folders (excluding the configuration files).
Can you save the file to cloud? if so then you could potentially upload the file to cloud and download the file to the new
My visual studio 2005 solution sometimes does not open the entire projects. To clarify what I mean by the “Entire projects”, my application is consisting of different layers such as DAO, Domain, Service, Utility and finally Web.App that contains all of my .aspx, .asxc and code behind files. Each layer consists of large amount of .CS and .VB classes. So, when I open the solution file (.sln), it only opens the Web.App project without opening the others.
Has anybody encountered this kind of issue in VS2005 and if you have had what you did to fix it, please let me know. So, basically when I open the project .sln, it only shows the Web.App project not the other projects. This does not happen all the time, but happens once in a while.
Is it because Visual Studio 2005 was not installed correctly or missing some updates? Any ideas or suggestions are highly appreciated. Thank you so much
Have you tried creating a new solution and adding all the relevant projects to see if perhaps your current .sln is corrupt?
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.
