Whenever I tried to copy 4 files into my bin folder, after stopping the main service, I am getting an error with one file (TexteDll). The error is:
Cannot copy TexteDll: The requested operation cannot be performed on a file
with a user-mapped section open
It may be due to some system locking. Or perhaps another process is using this DLL. When I googled, I found that rebooting the system may resolve this.
Can anybody suggest a cause or solution for this? I inspected the properties of TexteDll (general, version, security, etc). Everything appears normal.

In my case it was the Explorer that was locking the DLL that was been compiled in the Debug folder... Strange, isn't it?
I found out using a tool called Unlocker.
Had to delete with Unlocker, even when it was saying that there was no lock over the file, and I couldn't delete the folder until I didn't delete that single file...
After that it compiled.
EDIT:
I found out why in my case this was happening. I had the DLL opened in a text editor inside Visual Studio...
