SignClient Plugin GRPC conflict Between Grpc dlls with Oracle

[vncoelho]

Even with ALL these *.dlls generated during build, I am having random behavior on SignClient Plugin according to the Plugins that the node is running.

However, I did not found which other Plugin has GRPC

maybe it is the RestServer that have internal GRPC

[vncoelho]

I solved this by not copying the GRPC library,

perhaps the library compiled caused problems when running in a different linux distribution

[vncoelho]

Reoppened, indeed I found that the problem is a conflict between OracleService and SignClient

Perhaps both needs GRPC, which one should load the library if my node will activate both plugins?

How to release the Plugins?

[vncoelho]

ping @shargon

[vncoelho]

Historically, if you go to https://github.com/neo-project/neo/releases/download/v3.8.2/OracleService.zip you will find the Grpc*.dlls there.
Correct, @superboyiii @superboyiii ?

It will conflict with SignClient from now on, both needs GRPC.
There is something we need to fix here before next release 3.9.0

Different GRPC version?

Different GRPC version?

No, the whole neocli and plugins are compiled in the same machine.
