Microsoft .NET JSON serialiser could get faster start-up Improved throughput and reduced application size are also on the drawing board for the System.Text.Json serialiser Credit: Dreamstime System.Text.Json, a JSON serialisation library in Microsoft’s .NET development platform, could add C# source code generation in an upcoming iteration. The change is designed to improve performance. Plans call for utilisation of new C# source generator capabilities to help the built-in serialiser in the following ways: Improve start-up and runtime throughput Reduce private bytes usage Improve IL (Intermediate Language) Linker friendliness by avoiding runtime reflection Efforts to utilise C# source generation in System.Text.Json were in a prototype stage as of mid-December. Microsoft envisions their coming to fruition in .NET 6.0, due in November of this year.
