[N3] RpcServer dll inside TokensTracker folder causes duplicated plugin loading

Open vncoelho opened this issue 3 months ago • 2 comments

Accidently, while investigating https://github.com/neo-project/neo-node/issues/928 I checked if some .dll from the published folder of TokensTracker might be missing.

It happened that it also copied RpcServer.dll (which is a dependency).

Then, it caused this error mentioned here https://github.com/neo-project/neo-node/issues/928#issuecomment-3587113188

I understand it is an error of the builder who created the neo-cli package and plugins. However, is this expected? If a folder have 2 dlls should the neo-node try to load both, even a RpcServer duplicated? ping @shargon @Jim8y

Did you read the issue, @shargon ? I know it is in use, the point is how it became in use, is this expected? Double load the same plugin?
