Orleans 2, Preview 3 - Bug

Trying to create custom AuthenticationHandler is throwing an exception in Orleans.CodeGenerator.

I've created this sample so it will be easily testable.

Prerequisites

Git Clone
Build Solution

Replication Steps:

Launch Project (F5)

Extra Information:

I've created AuthHandler which inherits from : AuthenticationHandler<JwtBearerOptions> which is not being used.
This is throwing a Orleans.CodeGenerator.CodeGenerationException during runtime in OrleansConfig.cs at Line 41.

Exception Details:

Exc level 0: Orleans.CodeGenerator.CodeGenerationException: (1,3052): error CS0266: Cannot implicitly convert type 'object' to 'Microsoft.AspNetCore.Authentication.JwtBearer.JwtBearerEvents'. An explicit conversion exists (are you missing a cast?)
(1,8967): error CS0266: Cannot implicitly convert type 'object' to 'Microsoft.AspNetCore.Authentication.JwtBearer.JwtBearerEvents'. An explicit conversion exists (are you missing a cast?)

Other

If it will throw an exception at Line 43 that Orleans.Runtime.SiloUnavailableException: The target silo became unavailable for message: it means that the applications is working fine.
