Xamarin Forms Best Practices Enable the XAML compiler

XAML can be optionally compiled directly into intermediate language (IL) with the XAML compiler (XAMLC). XAMLC offers a number of benefits:

• It performs compile-time checking of XAML, notifying the user of any errors.
• It removes some of the load and instantiation time for XAML elements.
• It helps to reduce the file size of the final assembly by no longer including .xaml files.

TPL Task Parallel Library mapping to Async Await

What is async/await?

The async and await keywords were introduced in .NET 4.5 to make calling async methods easier and to make your async code more easily readable. 

The async/await API is syntactic sugar that uses the TPL (Task Parallel Library) behind the scenes. If you wanted to start a new task and have code run on the UI thread after the task completes prior .NET 4.5, your code would have looked something like this:

Using async/await, the above code becomes just two lines of it.In the nutshell it does exactly the same thing.
The above code gets compiled behind the scenes to the same TPL code as it does in the first example, so as noted, this is just syntactic sugar, and how sweet it is!
