UnityEditor Compiling Error :: VisualStudio Crash

Hello guys, when i edit some scripts with VisualStudio and then get back to Unity it automatically compiles the scripts i edited but when it finishes VisualStudio crashes and i get the following error in the Unity-Console:

 error CS0016: Could not write to file `Temp/Assembly-CSharp.dll', cause: Sharing violation on path C:\Users\MyName\Desktop\Desk2\UnityProjects\Project Name\Temp\Assembly-CSharp.dll.mdb
 
 Compilation failed: 1 error(s), 0 warnings

Has anyone of you a solution for this problem ?
