hi,
While running an application in expression Blend the following error poped up.
Unable to copy file "obj\Debug\forms.exe" to bin\Debug\forms.exe". The process cannot access the file 'bin\Debug\forums.exe' because it is being used by another process.
How to sort it out ?

Hi , I finally sorted out the problem and it was corrected by deleting the bin and obj folder of the project from the place where the project is saved. for ex. my proj name was Forms saved in my documents/blend so i deleted Documents/Blend/Forms--------> from here i delete bin and obj folder. as these folders are recreated by building the project.

The only time I get that error is when another instance of the program is still executing. Usually I have simply forgotten to exit from a previous test. Sometimes the problem is caused by a bug that causes the message loop (or let' call it the form) to close but the program continues to execute. It is likely that the problem is gone by now but in the future, the first thing to check for is a previous instance of the program. You might need to use the Task Manager to find it.

This kind of issues normally comes if the .exe or any other file which IDE is trying to use but doesn't have enough privilege to access the folder, sometimes this may also happen bcoz of the read only property of the specific file. If you can ensure about the privileges of the folder or read only of the files hopefully you can solve this issue.

make sure your if you have a UserControl or anything open in the designer/IDE, then close that and than try again.
