Answer 1

You can also try closing VS, deleting the bin directory then attempting to debug again – it has worked for me.

Answer 2

I found this SOF article and tried everything listed.

And I found a new caveat to this voodoo.

Mine falls under the "the dumbest reason ever" category.

My temp folder was "full". So I did a disk clean up, and that deleted the FILES. However, I had a large amount of subfolders in my temp folder and while they were empty, the folders themselves were causing GetTempFile functions to fail.

So when I ran

"C:\blah\blah\blah\IDE\devenv.exe" /log

the log entries in ActivityLog.xml were showing something like this:

System.IO.IOException: The file exists.

   at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
   at System.IO.__Error.WinIOError()
   at System.IO.Path.InternalGetTempFileName(Boolean checkHost)
   at System.Windows.Input.Cursor.LoadFromStream(Stream cursorStream)
   at Microsoft.VisualStudio.Text.Editor.Implementation.LeftSelectionMargin.get_RightArrowCursor()
   at Microsoft.VisualStudio.Text.Editor.Implementation.LeftSelectionMarginProvider.CreateMargin(IWpfTextViewHost textViewHost, IWpfTextViewMargin containerMargin)
   at Microsoft.VisualStudio.Text.Utilities.ContainerMargin.<AddMargins>b__2(IWpfTextViewMarginProvider mp)
   at Microsoft.VisualStudio.Text.Utilities.GuardedOperations.InstantiateExtension[TExtension,TMetadata,TExtensionInstance](Object errorSource, Lazy`2 provider, Func`2 getter)

In that log entry text, don't miss the text "System.IO.Path.InternalGetTempFileName"

So several places said "delete your temp files", which I did, but I still got the same issues. :(

Then I took a look at the temp directory, and I saw something weird. A large amount of (empty) subfolders.

So once I discovered I had a bunch of subfolders in my temp directory, I cleaned up these subfolders.

I found this question:

How to delete files/subfolders in a specific directory at command prompt in Windows

So I used this code:

I put this code in a .bat file

del /q "C:\Users\MYUSERNAME\AppData\Local\Temp\*"
FOR /D %%p IN ("C:\Users\MYUSERNAME\AppData\Local\Temp\*.*") DO rmdir "%%p" /s /q

And now my Visual Studio is running ok again.

Wow, go figure.
