so i was in the middle of making a program, when i decided to try upgrading to vs2015 just because i like the newer UI.
so i opened the .sln in vs2015 test run the program again, and re arrange the ui of my program, but i didnt add or remove anything, or even touched the code.
saved the file, and tried opening it again on my laptop that still on vs2010.
i can open the solution,i can access and edit the code, but i can't open the designer at all, or run the program that i made.
although i can also upgrade the one on my laptop to the newer one, im doing this project with a friend that is also still on vs2010, is there any way to make it compatible again?
Whenever you try to open the project in visual studio 2015 which was basically developed in visual studio 2010 will prompt the window for the make some changes in the .sln file also it shows all changes in the browser.
If you try to open that file which is changed by the VS2015 will not be able to open in VS 2010 but available to open in VS 2012 and on word
We have a really big solution with more than 200 projects and thousands of files. Despite of that the solution used to load pretty quickly in Visual Studio 2010 as well as 2012. However, after copying the whole SVN repository to another location, loading and closing the solution suddenly took extreeeemly long. (I am talking about 30-60 minutes here!)
I found a solution myself and I wanted to share it here, hoping that it might save someone quite a few hours of research and staring at the "Preparing solution..." dialog.
When inspecting the devenv.exe process with Process Monitor, I found out that it is pretty busy with accessing the .svn directory. Here is what I did (and this somehow solved the problem):
Kill Visual Studio
Open Visual Studio without loading a solution
Disable AnkhSvn as Source Control plugin (Tools->Options->Source Control->Plug-in Selection->None)
Disable "Document Well 2010 Plus" (VS2010) or "Custom Document Well" (VS2012) in Productivity Power Tools (Tools->Options->Productivity Power Tools) - I read that somewhere and it might have helped as well...
Close Visual Studio
Delete the solution's *.suo file. This is located in the same folder as the solution itself. NOTE: You will lose several settings for your solution, like currently opened files, breakpoints, bookmarks, current solution configuration & platform (e.g. Debug x86) etc.
Restart Visual Studio
Load the solution - it was much faster now!
Close Visual Studio
Open Visual Studio without loading a solution
Re-enable AnkhSvn and the "Document Well"
Restart Visual Studio
Open the solution - it was still loaded in seconds!
I do not know which of these steps actually solved the problem. Probably, not all these steps are required, but I did not want to reproduce the problem to find out which steps may be omitted. :)
None of those helped me, what I did... I watch with ProcMon of sysinternals, filtering for devenv, and I saw a lot of entries of fussionlog. I had enabled fussionlog for debugging purposes some weeks before and didn't think in disabling it. I just had to disable fussionlog and the solution opened faster.
You can open the Visual Studio in the Safe Mode, and then check your plugin and source control settings after opening the project.
Safe Mode means "Starts Visual Studio, loading only the default environment and services."
How :
devenv /SafeMode
Or according to your path
"C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\devenv.exe" /SafeMode
source : https://msdn.microsoft.com/en-us/library/ms241278.aspx
In my case, the following worked without any of the intervening steps suggested:
Kill Visual Studio.
Start Visual Studio directly (i.e., not from the .sln file).
Then, from within Visual Studio, open the solution.
In my case this was all it took to make the problem solution load quite quickly, without the need for me to change any settings or delete any files.
fwiw, I realize this is a late entry, but I found that simply removing (deleting) my large number of breakpoints resolved the excessive load time and compile time.
This action reduced the size of the .suo file from 214MB to 977KB. Let VS handle the .suo file itself.
Compiling and loading now takes < 1 minute instead of 5-10 minutes for a solution with 35 projects. Visual Studio 2012 Pro, update 4.
None of the other answers worked for me. CI compile times were fine, but loading my solution in Visual Studio was taking almost two minutes. VS would then operate just fine until I closed and opened the solution the next time. Different versions of VS all showed the same problem and both safe mode and deleting the suo didn't help.
I ended up following the advice in http://geekswithblogs.net/akraus1/archive/2014/04/30/156156.aspx to use Windows Performance Recorder to instrument VS and find the problem. By looking in Windows Performance Analyzer under the "CPU Usage (Sampled)" section and adding the "Stack (Frame Tags)" column, I was able to dig into the usage of devenv.exe.
Turns out the hot path by count had Microsoft.VisualStudio.Platform.WindowManagement.ni.dll 23 calls down, and below that eventually Microsoft.VisualStudio.ServerExplorer.dll and Microsoft.VisualStudio.Data.Package.dll. That pointed me to look in Server Explorer in the UI and open the Data Connections tab. There I found hundreds of mistakenly added connections that came from the debug web.config's ConnectionString section. Removing those from web.config reduced the load of that individual project from 90+ seconds to almost instant.
I have a different cause for the slow loading of the projects.
My situation is utilizing Git and found that even switching branches was slower than it should be with project load.
Solution: Run Visual Studio as Administrator
Reason: Something with the Corporate laptop is not providing the needed Git tool access (it doesn't recognize that a git repository is in use).
I have not seen any issues with Git or my personal access to any of the project files or Git objects.
I tried the above, but it didn't solve my problem.
Here's how I got around this problem, hopefully it will work for some of you as well:
Open Visual Studio 2013 with no solution.
Create a new C# Console application and save it.
Close Visual Studio.
Reopen the Console solution created in step 2.
Close Visual Studio.
Reopen the solution that was previously hanging on the Preparing Solution dialogue. Mine opened right away, no more hanging.
Using Visual Studio 2015, I ended up creating a new solution, adding the existing projects.
Deleting the *.suo from gehho's answer helped in the past, but didn't help me in this case. There's also another .suo file in a hidden .vs folder at the root of the solution.
There are other answers here for Visual Studio 2015 Visual Studio 2015 is extremely slow
For my case it was due to TFS issue. It thinks that there are more than 5000 pending changes.
The fix is to force TFS to recheck. Go to Team Explorer -> Source Control Explorer and do "Get Latest" on the projects that have pending changes. For things that are already matching TFS, Visual Studio will actually not download anything to your PC. For things that are different with TFS, Visual Studio will let you know and ask you to reconcile the difference.
This is VS 2019 Professional.
In my case there were <import ...> entries in the project files that pointed to
paths no longer available making the loading of the solution hang indefinitely without any form of information give (Shame on Microsoft!).
I encountered this problem only recently (Mar 2021), using VS 2019. It literarily takes 30+ seconds to load the file (each).
It only effects the Layout files. I believe it could be to do with the links within the files. I have not had time to investigate them.
However, I am writing this to suggest that regardless of the cause of the problem, a simple solution is to right click on the file and open it with Notepad to get your work done.
Here is the situation:
I checkout a new project to directory. I open a solution and it stucks at loading project XYZ.
What I see is loading window and "Loading XYZ..." on the statusbar.
The solution we made up is the following:
Open the solution (let's say its name is Solution.sln) in a notepad
Remove the problematic XYZ project
for example:
Project("{FAE04EC0-301F-11A3-BF4B-00C04F79EFBC}") = "HelloWorld.Tool.XYZ", "HelloWorld.Tool.XYZ\HelloWorld.Tool.XYZ.csproj", "{F614BEF7-B429-487D-9055-01BC9FD543EC}"
EndProject
Reopen the solution
But when there are more such problematic projects in a solution
Visual Studio stucks at the other projects. Sometimes it happens that there are a few projects to remove at once then Visual Studio starts. Then I add projects via notepad one by one repeating the proccess of reopening solution.
As you see this proccess is often very tedious and time-consuming.
Why it happens? How to solve it in a simpler manner?
I am using Visual Studio 2010 with Resharper
EDIT: Suspending Resharper didn't help
My visual studio 2010 crashed when some carelessness [bit of madness] mistakenly pressed start button and my Acer timeline got unstable. Two projects where open at the time, one in visual studio 2005 [I have both 2005 and 2010 installed]. Unfortunately I lost all the codes I had done at the time along with those coded even weeks before. Now the project files in both the solutions are those weeks older. Amazingly, the .aspx pages are intact and .cs files are gone.
What can be done to get the lost data? Help please.
Thanks.
Guys TAKE CARE if your Visual Studio crashes, you need to check the backup BEFORE you restart Visual Studio and check if your files are ok! Many people complain that they lost work after a crash, and then they restart Visual Studio, and upon discovering that their code cannot be found in Visual Studio they then check the backup at the location
%USERPROFILE%\Documents\Visual Studio 2010\Backup Files\\
The order is important. Check the backup FIRST, before restarting Visual Studio. If you start Visual Studio and then open your old project it's probable that Visual Studio will overwrite the backup files for that project.
Securing the backup is your FIRST concern. Then start Visual Studio and open your project to see how much damage there is.
You can check:
C:\Users\<username>\Documents\Visual Studio 2010\Backup Files\<ProjectName>\
C:\Users\<username>\Documents\Visual Studio 2005\Backup Files\<ProjectName>\

I just had the same experience -- losing a source file during a BSOD. Very annoying!
No backup file could be found, and I searched the hard drive for a file containing the class name, but no backup was unturned.
However I was able to get back something resembling my code by decompiling a DLL from the bin/Debug folder using DotPeek. So if you had previously compiled your code successfully, you can get the code (without comments, and with some weird local variable names, etc) via decompilation.
I Had the same problem, I lost code due to BSOD.
the backup folder should store files not saved until they are saved whenever you save the files there are deleted.
I think that maybe they don't remain after a restart as it was empty in my case.
A very good file recovery tool is Recuva. It helped me once, didn't help me second time, though, because I noticed the data loss too late, and all recoverable data got overwritten.
So I used DotPeek, though you'll have to do a lot of work on the disassembled files, they are pretty weird.
Now I put my source tree in Google Drive, because it has file versions and keeps deleted files. Dropbox would do, too.
Git or any other VCS are not solution for this thing, because you cannot have crazy amount of meaningless commits.
We're using VS 2010 and GIT. Occasionally, after a git pull, all open files will close--seems like this happens when new files are added to the project. I can't seem to find a related file that shouldn't be in version control. Has anyone else had this issue?
I figured out a solution to this. It's a little annoying but it works around the tedious task of re-opening all of your tabs/files in VS.
When you get the VS warning that the Project has been modified outside of VS it asks if you want to reload the project. Choose "Ignore."
Next, save all your work, close VS and reopen your solution or project. All the files/tabs you had open previously will be open again and the updates to the project file, obviously, will also be loaded.
Another caveat to this is you lose all your "Undo" potential in your open files.
When a .vcproj file gets touched (not necessarily changed), all its opened files are closed and never reopened. Might this be what you are experiencing?

It's a visual studio add in that will keep your files open upon reloading. It's tremendously useful and will keep you from having to go through those ridiculous steps. Productivity++.
