JSON source-generation API refactoring
The APIs that the output of the JSON source generator calls have been refactored. The refactoring makes them easier to extend with new features in the future. Projects that explicitly use the JSON source generator and were compiled with .NET 6 RC 1 or earlier will fail with run-time exceptions when run on the .NET 6 RC 2 runtime.
Previous behavior
Projects that were compiled using the .NET 6 RC 1 or earlier version of the System.Text.Json source generator and library run as expected.
New behavior
Projects that were compiled using the .NET 6 RC 1 version of the System.Text.Json source generator and library fail when run against the .NET 6 RC 2 runtime. Projects that are recompiled with the RC 2 SDK work as expected.
Version introduced
6.0 RC 2
Type of breaking change
This change can affect binary compatibility.
Reason for change
This change was introduced to make it easier to extend the source-generator implementation with features in the future. For more information, see dotnet/runtime#59243.
Recommended action
Recompile your app using the RC 2 SDK.
