How to call asynchronous method from synchronous method in C#?

Question

I have a public async void Foo() method that I want to call from synchronous method. So far all I have seen from MSDN documentation is calling async methods via

Answer 1

Here is the simplest solution. I saw it somewhere on the Internet, I didn't remember where, but I have been using it successfully. It will not deadlock the calling thread.

    void Synchronous Function()
    {
        Task.Run(Foo).Wait();
    }

    string SynchronousFunctionReturnsString()
    {
        return Task.Run(Foo).Result;
    }

    string SynchronousFunctionReturnsStringWithParam(int id)
    {
        return Task.Run(() => Foo(id)).Result;
    }
