I had the same problem. I changed my VS2015 settings and it seems the problem is gone:

• disabled Options\Debugging\Edit and continue
• -Options\Sourcecodemanagement from TFS to none-
• -disabled Options\Debugging\Diagnostictools while debugging-

Not sure wich one caused the locking, but i suspect the diagnostictools wich I did not have in VS2013. (The settings names I translated from German to english, don't know if it is exactly how they are called in english VS version.)

Edit: As researched by Shea it was the Edit-And-Continue feature that locked the DLL.
