### Hi!

Today I was forced to use .NET Framework MVC 5 (not core!!) as a small sample/test project. And I felt into a trap…

… as I generated boilerplate MVC app and move on to proper implementation.

I was supposed to fetch data from the external API and show them on the web. As simple as it looks like.
With additional class, it was 7 lines of code. Approx. 4 mins of writing. And done.

But wait…

Debugger attached, code executed, API called but no result returned. It took me an additional 5 or 10 mins to figure out the problem.

.Net Framework MVC boilerplate is by default SYNC.

public ActionResult Index()

.Net Framework Core MVC boilerplate is by default ASYNC.

public async Task<IActionResult> Index()

I’m so used to .Net core, that it took me so much time to figure out, that I forgot to await my code and change the action signature to async one.

As the only symptom of such a situation was debugger never going into the code that was after first await keyword. It was the only clue that I forgot about async signature…

Shame on me
