Async exception not being caught or being swallowed

Question

Update from the future: TL;DR to catch expressions in async methods you have to await, Task.WaitAll, or .Result.

Answer 1

I'm going to add an answer to my own question because there's a useful piece of information that I found out. The intermediary method LoadMSpecAsync is swalloing the exception. For this not to happen it needs a little teak. You need to add the async keyword before the return type and the "await" keyword after "return".
