Using Google API GoogleJsonWebSignature.ValidateAsync(…) in server call

Question

I am trying to implement Google SSO in my C# web application. It seemed to be pretty straightforward. Based on this tutorial, Google does its magic in the web browser

Paulo, Thank you!!

I was able to get this working with your advice on the last part about the test method. I had to change this:

//THIS TEST METHOD DOESN'T SHOW IN THE TEST EXPLORER

[TestMethod]
public async void AuthenticateGoogle()
{
    string lToken = "[JWT TOKEN HERE]";
    wfUser lUser = new wfUser(_wfContext);
    var lAuthenticateResult = await lUser.wfAuthenticateGoogle(lToken);

    Assert.IsTrue(lAuthenticateResult, "JWT Token Validated");
}

To this:

//THIS TEST METHOD SHOWS IN THE TEST EXPLORER

[TestMethod]
public async Task AuthenticateGoogle()
{
    string lToken = "[JWT TOKEN HERE]";
    wfUser lUser = new wfUser(_wfContext);
    var lAuthenticateResult = await lUser.wfAuthenticateGoogle(lToken);

    Assert.IsTrue(lAuthenticateResult, "JWT Token Validated");
}

NOW -- as an additional gotcha that was hanging me up, this will also cause a unit test to disappear from the test explorer, which I found out through lazy copy/pasting a non-test method's definition and mindlessly just adding a return when the build output told me I needed to return a value.

//THIS TEST METHOD DOESN'T SHOW IN THE TEST EXPLORER DUE TO RETURN VALUE

[TestMethod]
public async Task AuthenticateGoogle()
{
    string lToken = "[JWT TOKEN HERE]";
    wfUser lUser = new wfUser(_wfContext);
    var lAuthenticateResult = await lUser.wfAuthenticateGoogle(lToken);
    Assert.IsTrue(lAuthenticateResult, "JWT Token Validated");

    return true;
}

In addition to the excellent blog you shared, this article from MSDN Magazine entitled Async Programming : Unit Testing Asynchronous Code helped me get my brain around it too.

What was hanging me up with all of this was mixing synchronous and async methods which, to your point, was not working well. The code seemed to skip the debug points I had set after the await calls as if it never ran them or, if it did run them, ran them somewhere I could not see and couldn't log to the debugger.

It was one of those terrible moments late on a Friday night where a developer starts to question both competence and sanity! :)

Thanks again for the help!

p.s. I incorrectly typed Angular JS in my question and meant Angular 4...and I am using TypeScript there. Some day I'll stop incorrectly referring the newer versions of Angular as AngularJS.
