𝗘𝘅𝗽𝗹𝗼𝗿𝗶𝗻𝗴 𝗖# 𝟭𝟮 𝗳𝗲𝗮𝘁𝘂𝗿𝗲𝘀 blog series 💡 Really enjoyed this four part series from David Pine on the main MS devblogs site which looks at how we might apply some of the new features of C# 12 such as primary constructors and collection expressions to our codebases.

.NET 8 new static code analyzers 💡I'm a big fan of using tooling where possible to help us improve our code and these new analyzers added in .NET 8 should help. Note ... CA1864 is not shown below but was also added in .NET 8 and catches occurrences of a Dictionary.Add call guarded by Dictionary.ContainsKey.Which ones will you turn on?

𝗥𝗲𝗮𝗱𝗢𝗻𝗹𝘆𝗦𝗲𝘁<𝗧> coming in .NET 9 💡We already have ReadOnlyCollection<T> and ReadOnlyDictionary<TKey, TValue> but no ReadOnlySet<T>. A PR has been merged for this and I'd expect it to be released with .NET 9 Preview 6 in the 2nd or 3rd week of July.

𝗚𝗲𝗻𝗲𝗿𝗶𝗰 𝗢𝗿𝗱𝗲𝗿𝗲𝗱𝗗𝗶𝗰𝘁𝗶𝗼𝗻𝗮𝗿𝘆 coming in .NET 9 🔥.NET does not currently have a genericOrderedDictionaryclass which has meant many of us have rolled own our solutions. Thankfully a PR adding a generic OrderedDictionary was merged two days ago and should be released with preview 6. This is awesome and should allow many of us to remove custom code and get the best performance from the built in implementation.

.NET 9 optimized static web asset delivery with new middleware 💡In .NET 9 (Preview 5+) 𝗠𝗮𝗽𝗦𝘁𝗮𝘁𝗶𝗰𝗔𝘀𝘀𝗲𝘁𝘀 is a new middleware that helps optimize the delivery of static assets in an app. It works with all UI frameworks, including Blazor, Razor Pages, and MVC. MapStaticAssetsoperates by combining build and publish-time processes to collect information about all the static resources in an app. This information is then utilized by the runtime library to efficiently serve these files to the browser by utilizing techniques such as 𝗯𝘂𝗶𝗹𝗱 𝘁𝗶𝗺𝗲 𝗴𝘇𝗶𝗽 𝗮𝗻𝗱 𝗯𝗿𝗼𝘁𝗹𝗶 𝗰𝗼𝗺𝗽𝗿𝗲𝘀𝘀𝗶𝗼𝗻.The image below (from MS) shows the original and compressed sizes of the CSS and JS files in the default Razor Pages template.What do you think?

The simple example below makes multipleHttpClientcalls and is able to operate on their results as they complete. What do you think?

Vertical Slice Architecture example 💡In this simple example everything (except .cshtml) is in one file, it's very developer friendly. No hopping between multiple projects, no repository pattern, no specification pattern, no MediatR, no indirection, no abstraction fetish that we typically see in our apps, no bloat ... just enough code to meet the requirements of the use case. Of course it's not going to work for all apps and use cases but try and at least consider if this approach will work for you.
