The link doesn't try to decipher the cause of the problem and thus it works or not. Not it is in my case.

@Tomas Pajonk: The cause of the problem is most likely the fact stated by the error message; your target is being used by another process. To find out, which process, you can use Process Explorer from Sysinternal; press Ctrl+F and search for "Arrowgrass Reports.exe"

Just in case anyone is still interested in this, I've noticed that the problem only occurs when user defined controls are used. It looks like Visual Studio itself is the other process, as it is rendering the control. I found that as long as this control was not on the screen, I didn't get the error.

Answer 2

+4 A:

I have found this issue very easy to reproduce, and the fix for me is a variation on Richard Fors' answer. If I have a UserControl open in the designer, run the debugger, and then edit the UserControl, the subsequent rebuild will fail. If I close the UserControl before running the debugger I never get this error, so I just make sure to close the designer window before hitting F5.
