Whoa! .NET 5 is out and C# 9 is out! This means you are ready to use records, new pattern matching, and more! But wait a second... your apps haven't been upgraded to .NET 5 yet or are a project type that don't support .NET so you don't have access to the new C# 9 features :( Or do you!?!?!?! Yes, of course you do! Most new features in C# are compiler based and not necessarily runtime based. When you create a new …

C# 8 was officially released in September at .NET Conf along side .NET Core 3 & Visual Studio 16.3 (8.3 on Mac). It is packed with tons of amazing new features that truly everyone should be using. However, there is a lot of confusing as to if you can actually use C# 8 if you aren't using .NET Core 3 or .NET Standard 2.1.

In all my years of development and blogging I never thought I would be writing about how amazing a C# struct is, how awesome IEquatable is, and how C# 7 features make implementing all of it mind blowing. In Xamarin.Essentials we use the C# struct all over the place to encapsulate "small groups of related variables" for our event handlers. They are groups of data that don't need to be created by the …

Watch Now, Questions Later Want to see it in action? Checkout my short video overview:

I love async/await Task based programming! I talk about it in all my demos, it is in all my libraries, and Frank and I did a whole Merge Conflict podcast episode on it. The problem is that I keep getting bug reports and seeing samples where it is being abused and used completely wrong. I am never a fan of calling a lot of async code in a constructor or in the OnCreate/AppDelegate, but the real issue is when I see …

I can’t help myself, I love Expression-Bodied Members from C# 6! Combined with other powerful C# features it took this code: public void OnPropertyChanged(string name) { var changed = PropertyChanged; if(changed == null) return; changed(this, new PropertyChangedEventArgs(name)); } to this: public void OnPropertyChanged(string name)=> PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(name)); This is …

In 2006, after years of writing C++ and Java code, while attending UAT an instructor named Phil Miller introduced me to this amazing language called C# and changed my life. It was love at first “Hello World” and I have never looked back. C# is an extremely powerful, mature, and extremely cross-platform programming language that I have been using for decades. The beauty of C# of course is that you get this amazing …

So you are probably using GridViews and ListViews all over the place. In some instances you will most likely even have a situation where you you have a DataSource with a few DataGroups. Each DataGroup might actually be all different or it might even have different items in its list. If you have a nice base class such as StandardDataItem then this will work just fine. So here is where the fun comes in because usually …
