The return type of an async method must

Answer 1

The rule is simple: if your "regular" synchronous method would return T, your async method must return Task:

private static async Task GoRequest(string url, Dictionary parameters, HttpMethod method,string body = "")
        where T : class

You don't need to change anything else: when your async code returns a T, the compiler makes sure that the result is actually a Task.

Note: Since your async method has no awaits in it, you might as well change it to a "regular", synchronous, method.
