Not compatible with graphql-dotnet 3.0

[withinboredom]

In the latest of graphql-dotnet UserContext is expected to be a Dictionary<string, object> and not an object.

This could probably be handled by adding a simple bit:

// var userContext = context.UserContext as IProvideClaimsPrincipal;
IProvideClaimsPrinciple userContext;
if(context.UserContext is Dictionary<string, object>) {
  userContext = (context.UserContext as Dictionary<string, object>)?["user"] as IProvideClaimsPrinciple;
} else {
  userContext = context.UserContext as IProvideClaimsPrinciple;
}

Can you explain the problem in more detail?

Sure, the ValidationContext implements IProvideUserContext which an IDictionary and not an Object (like it was in earlier versions). This means, in the very least, that either:

1. GraphQLUserContext needs to also implement IDictionary<string, object>
2. or, GraphQLUserContext needs to check a "well-known" key for the principle.

As it stands right now, it doesn't work at all unless (1) is implemented because ExecutionOptions only accepts an IDictionary<string, object>

the ValidationContext implements IProvideUserContext which an IDictionary and not an Object 

This is the expected behavior. https://github.com/graphql-dotnet/authorization/blob/master/src/Harness/GraphQL.cs#L8 , examples have been modified accordingly.

Do you have a runtime error?

Oh, nice I missed that! Closing this :)
