I help clients go faster for less using serverless technologies.
With the official release of .Net 4.5 and Visual Studio 2012, I suspect many .Net developers will be rushing to rewrite their data access or network layers (amongst many many other things!) to take advantage of the new async-await (see the excellent 101 examples here) language feature in C#, which means you’ll likely be working with the Task and Task<T> type an awful lot.
If you have F# code that needs to interop with C# that returns or awaits some task types then you’ve probably already come across the Async.StartAsTask<T> and Async.AwaitTask<T> methods for converting between F#’s Async<T> and Task<T> types. Curiously, there are no equivalent methods on the Async class for converting between Async<unit> and Task types.
So, to fill in the gaps ourselves, here are two simple functions to do just that:
Enjoy!
Whenever you’re ready, here are 3 ways I can help you:
- Production-Ready Serverless: Join 20+ AWS Heroes & Community Builders and 1000+ other students in levelling up your serverless game. This is your one-stop shop to level up your serverless skills quickly.
- Do you want to know how to test serverless architectures with a fast dev & test loop? Check out my latest course, Testing Serverless Architectures and learn the smart way to test serverless.
- I help clients launch product ideas, improve their development processes and upskill their teams. If you’d like to work together, then let’s get in touch.
As a Task is also a Task (https://msdn.microsoft.com/en-us/library/dd321424(v=vs.110).aspx), you can also just do:
`let StartAsPlainTask x = Async.StartAsTask x :> Task`
