Releasing and reloading DLL in editor?

I use a custom native DLL in my game which is built for each platform I deploy to.

I'm using Unity 5 64bit Windows version. To run my game in the editor I build my native library as a Win64 DLL for the editor to use, this works great.

But..

Every time I update the library (which is often) if I have run the game in the Editor (and it's no longer playing) I am unable to overwrite the current DLL in use by the Editor.

Question:

Is there any way to have Unity release its lock on the DLL and then reload it next time I click play? As it is now I need to exit Unity, copy over the DLL and restart Unity - rather laborious and time consuming to do 50 times a day (ohhh, the first world problems... poor me.... )

 

Here's a great workaround:

Thanks Tomas1856 and JonathanBolten,

I'll give that workaround a shot.

 

It seems like the situation has not changed in Unity 2020.1?
You still have to restart the editor if you want to update a native DLL?
