I am having an annoying problem with a DLL.
Well, i needed to make a test with two different versions of a DLL on an application on IIS.
I renamed the original dll Primavera.ERPOnline.Bso.Proxy.dll to _Primavera.ERPOnline.Bso.Proxy.dll, and copy the new version to the folder.
After all the tests i removed the new dll and renamed the _Primavera.ERPOnline.Bso.Proxy.dll to the original name.
I made an iisreset, and try to initialize the application but for some reason i get an error, and i cannot start correctly the application:
Exception message: Could not load file or assembly '_Primavera.ERPOnline.Bso.Proxy' or one of its dependencies. The process can not access the file because it is being used by another process. (Exception from HRESULT: 0x80070020
What do i need to do to "delete" that referece to that dll?
