Converting Strings to .NET Objects – IParsable and ISpanParsable

A new feature of C# 11 allows abstract static members with interfaces. This makes it possible to define class methods to be used as a contract with a generic class implementation, e.g. using + and – operators. With .NET 7, numeric types implement many new interfaces. This C# 11 feature is not only about math! The new IParsable and ISpanParsable interfaces allow creating objects from strings. As these interfaces can be used with constraints in generic types, parsing strings to create objects is now an easy task with generic implementations. This article shows implementing both the string and the Span version of the parse interfaces and using them with generic types.

Creating Windows applications, UI controls are bound to the UI thread. .NET made it to different iterations with different patterns dealing with asynchronous programming. .NET 4.0 introduced the Task Parallel Library (TPL) and C# 5 added the async and await keywords. Together with these enhancements of .NET, and the synchronization context, invoking methods that make use of different threads has becoming a lot easier.
