Answer 2

I have overcome this problem by renaming the locked file (using Windows Explorer). I was not allowed to delete the file, but renaming the locked file works!

I had the same issue on my Xamarin application in visual studio and it was resolved by unplugging my test mobile device.

It only stopped after i unplugged the device because i had to receive a call.

Answer 5

I had the same issue and could not rectify by using any of the methods mentioned in previous answers. I resolved the issue by killing all instances of "SSIS Debug Hist (32 bit)" in task manager and now working as normal.
