WebAssembly & ASP.NET Blazor: .NET auf dem Weg, den Browser zu erobern?

.NET 8 brings Native AOT to ASP.NET Core, but many frameworks and libraries rely on unbound reflection internally and thus cannot support this scenario yet. This is true for ORMs, too: EF Core and Dapper will only bring full support for Native AOT in later releases. In this post, we will implement a database access layer with Sessions using the Humble Object pattern to get a similar developer experience. We will use Npgsql as a plain ADO.NET provider targeting PostgreSQL.

Originally introduced in .NET 7, Native AOT can be used with ASP.NET Core in the upcoming .NET 8 release. In this post, we look at the benefits and drawbacks from a general perspective and perform measurements to quantify the improvements on different platforms.

.NET 8 introduces a new Garbage Collector feature called DATAS for Server GC mode - let's make some benchmarks and check how it fits into the big picture.

With the version 4.3.1 of Microsoft.CodeAnalysis.* Roslyn provides a new high-level API - the method "ForAttributeWithMetadataName". Although it is just 1 method, still, it addresses one of the biggest performance issue with Source Generators.

There is this popular quote by Jamie Zawinski: Some people, when confronted with a problem, think "I know, I'll use regular expressions." Now they have two problems."

In this second article of our short performance series, we want to look at the latter one of those problems.

Wie in allen anderen browserbasierten Single-Page-Application (SPA) Frameworks, ist Blazor WebAssembly JSON-over-HTTP (über Web- oder REST-APIs) die bei weitem häufigste Methode, um Daten auszutauschen und serverseitige Vorgänge auszulösen. Der Client sendet eine HTTP-Anfrage mit JSON-Daten an eine URL, mitunter über unterschiedliche HTTP-Verben. Anschließend führt der Server eine Operation aus und antwortet mit einem HTTP-Statuscode und den resultierenden JSON-Daten. Warum sollte man das ändern? Nun, es gibt Gründe - vor allem wenn man in einem geschlossenen System ist und .NET sowohl im Frontend als auch im Backend einsetzt.
