No Async method working

My complete Kinvey and Xamarin Async-API is not working with await/async methods. I dont know where the problem is. I didn't find any error in my code, but the general methods I use should be ok, like 

User _User= await KinveyXamarin._Client.User().LoginAsync();

I searched on the Internet, but I didn't find any similar problems. It returns the Compile_time Error

Error CS4033: The 'await' operator can only be used within an async method. Consider marking this method with the 'async' modifier and changing its return type to 'Task'.

I really dont know whats causing this problem, these are nearly my first steps with asynchronous API and Kinvey. Any help would be greatly appreciated.

The method in which you write await should be an async method itself.

public async Task MyMethodAsync()
{
    User _User = await KinveyXamarin._Client.User().LoginAsync();
    // more code
}

If you want to return an object, use Task<T>:

public async Task<User> MyMethodAsync()
{
    User _User = await KinveyXamarin._Client.User().LoginAsync();
    // more code

    return _User;
}

Extra note: please try to avoid async void, it's evil.

Edit: it's a best practice to end your async methods on -Async to make this clear to anyone using your code.
