Debugging / unloading PowerShell Cmdlet

Question:

I am writing a PowerShell Cmdlet in C# using Visual Studio 2015. Debugging it works fine, but I cannot rebuild the DLL until I close the PowerShell window. The DLL seems to be in use and therefore cannot be deleted (not on the command line nor using explorer). I tried remove-module. This successfully removes my Cmdlet but I still cannot delete / overwrite it.

It is very unhandy to close PowerShell, rebuild the DLL and then reopen a new PowerShell, cd to the DLL path (usually deeply nested), re-import it again, start the command to debug, and so on for every single debugging session…

Is there no better solution to unload the DLL?

Answer:

I’m afraid there is not much you can do about this behavior as far as I know. One trick is to immediately start a new PowerShell session inside your existing session before loading the DLL. Then you can exit out of the second one and you have a brand new without the DLL loaded. Just remember to start a new “secondary” session before loading it again in case you need to unload it again.
