What our readers say about the newsletter?

I've actually used a few of these at my job. I hope to use some of these in the near future with .NET 6.
This week was very informative, thank you! I haven't heard about standard feature flags before, and the post about LINQ was surprising. DiagnosticListener might also come in handy some day.
Great concept coverage on articles!
Loved the article about The Operation Result Pattern, which I recommended to friends and colleagues, and made me migrate my Azure Function to .NET 6.

By Reference in C#

I became aware recently that there were many C# compiler errors that do not have a corresponding documentation page. That documentation is open-source and I chose to spend some time contributing some pages for the community. Looking at a language feature from the perspective of its compile-time errors is rather enlightening, so I'd though I'd write a bit about these features in hopes of offering a better understanding for my readers.

Introducing C#11: Auto Default structs

C# 11 improves Structs compared to C# 10 (and earlier). Before C# 11, every Struct properties in the constructor had to be initialized or risk a compilation error. C# 11 fixes that and we will see how in this post.

Use .NET from any JavaScript app in .NET 7

.NET 7 provides improved support for running .NET on WebAssembly in JavaScript-based apps, including a rich JavaScript interop mechanism. The WebAssembly support in .NET 7 is the basis for Blazor WebAssembly apps but can be used independently of Blazor too.

Clean Code Tip: throw exceptions instead of returning null when there is no fallback

When you don't have any fallback operation to manage null values (eg: retry pattern), you should throw an exception instead of returning null.
