Starting with C# 7.1 features, a Main method (the entry point for an application) can be declared as async, and can return a Task. CC0068 incorrectly triggers stating that this method should be removed because it is unused. However, you cannot remove the Main method for an application otherwise it would not compile or run.

Coincidentally, if I change the Main method from async Task to just void Main, the rule does not get triggered as I would expect.

static async Task Main(string[] args)
{
    //Do something here
}
