Add Helper builder extension to use custom MethodProviders

[CSharpStudio]

I want to dynamic add methods to RpcRouteMetaData，but StaticRpcMethodDataAccessor is internal and I have to implemant IRpcMethodProvider myself. The problem is the RpcEndpointBuilder cannot be extented, and if I add a new UseJsonRpc method with MyRpcEndpointBuilder, I have to create another RpcHttpRouter because it is internal also.

This should be able to be done, just not with using any of the built in extension methods. Youll need to register a new IRpcMethodProvider in the servicecollection before calling AddJsonRpc(). Then if you call

var router = new RpcHttpRouter();
app.UseRouter(router);

for applicationbuilder, it should work for you. Try it out. if it doesnt work then i can fix it and/or add a helper method to the BuilderExtensions

Thanks, I fix it out with a RpcEndpointContainer like RpcEndpointBuilder and use a new UserJsonRpcRouter replace the UserJsonRpc method.
If the internal RpcRouteMetaData Resolve() changed to protected, it will be extended easier.

public static IApplicationBuilder UseJsonRpcRouter(this IApplicationBuilder app, Action<RpcEndpointContainer> configure = null)
{
     var container = app.ApplicationServices.GetService<RpcEndpointContainer>();
     if (container == null)
          throw new InvalidOperationException("AddJsonRpcRouter() needs to be called in the ConfigureServices method.");
     configure?.Invoke(container);
     return app.UseJsonRpc(options => { }); // the options of RpcEndpointBuilder is no use here
}
