We can't tell - we do not know what you did last time it worked to stop it working.
However, you can try adding it back in: Right click the solution in the Solution explorer, and select "Add...Existing Project". Follow the dialogs to put your project back in the solution.

The most common cause I've seen of this issue is failing to run Visual Studio in administrator mode. Many projects, such as websites, require admin mode to load.

The .vs folder was not created by any version of Visual Studio which was available when this already-solved question was posted. It was introduced by VS2015, whereas this question was posted in 2013.

Solution 4

In my case, run visual studio in admin mode solved it.
Apparently, I was earlier running VS in admin mode to allow "attach to process" while running local IIS

Thanks, you saved my day. i was facing same problem in asp.net in visual 2019 where im running my web on local IIS instead of IIS Express. Running visual studio as admin solved my problem.

Solution 2

you also open your project from the documents where the window application is saved ,i think if you run the application from the document then vs2010 and then the winform something u will be able to recover all the files!!!

Change the name of the folder back to what it was, and then it will work.

I got the same problem. Before the project become unloaded I had another error about file name. A word file it read had a very long name and the error was like "file name can not be longer than 260 characters." Because of this error I couldn't open my controller classes etc.
The word file was in temp folder and I deleted it then I had to do nothing but open the project again.

OP did not mention opening a Word document in their question and you would still have needed to add the project to the solution again - as already stated
