Cannot run embedded client in version 20.6.0

Dear all,

First of all, thanks for the eventstore and all the hard work you put in it.

I have an issue running the embedded eventstore . When I try to build the EmbeddedVNodeBuilder, I always get the following error :

Unhandled exception. System.TypeLoadException: Method 'get_Name' in type 'EventStore.Core.Authentication.InternalAuthentication.InternalAuthenticationProvider' from assembly 'EventStore.Core, Version=, Culture=neutral, PublicKeyToken=null' does not have an implementation.

My implementation of the embedded ES follows the docs :

  let nodeBuilt =

I have reproduced the error in this basic project :
you just have to :

dotnet tool restore
dotnet paket install
dotnet run

What am I doing wrong ? I have tried my luck with different versions of EventStore.Plugins, even tried adding the eventstore.Client , but nothing worked so far.

Thanks for your help.
