If I change anything on userContext from FieldsMiddleware or IValidationRule the change is not available in resolver.

Hi I am trying to experiment something for this i am trying to
change a value on the user context from within FieldMiddleware (tried ValidationRule as well).
But the changed value is not available inside the resolver.

I have prepared a small sample project to demonstrate the problem.
Startup class

public void ConfigureServices(IServiceCollection services)
        {           
            services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
            services.AddScoped<IFooService, FooService>();        
            services.AddSingleton<IDocumentExecuter, DocumentExecuter>();      
            services.AddSingleton<UserType>();
            services.AddSingleton<GraphQlQuery>();
            var sp = services.BuildServiceProvider();
            services.AddSingleton<ISchema>(new GraphQlSchema(new FuncDependencyResolver(type => sp.GetService(type))));
        }

GraphQlController - I am setting the _fooService on the userContext. From within the fieldmiddleware, I want to update the two properties of the fooService.

 var executionOptions = new ExecutionOptions
            {
                Schema = _schema,
                Query = param.Query,
                Inputs = inputs,
                UserContext = _fooService,           
            };

FieldsMiddlewareTest

public Task<object> Resolve(
            ResolveFieldContext context,
            FieldMiddlewareDelegate next)
        {
            var fooService = (IFooService)context.UserContext;
            if (fooService != null)
            {
                fooService.GivenName = "InstrumentFieldsMiddleware-GivenName";
                fooService.FamimlyName = "InstrumentFieldsMiddleware-FamilyName";
            }
            return next(context);
        }

GraphQlQuery - Inside my resolver. I am trying to use the values that I have updated in the fieldmiddleware. But the value FamimlyName and givenName remain null. For some reason the middleware changes are not available in the resolver.

 public class GraphQlQuery : ObjectGraphType
    {
        public GraphQlQuery(IFooService fooService)
        {
            Field<UserType>("users",
                resolve: context =>
                {                    
                    return new User() { FamilyName = fooService.FamimlyName??"QueryFamilyName", GivenName = fooService.GivenName??"QueryGivenName" };
                });
        }
    }
