System.Text.Json — .NET 11
Three APIs were added to System.Text.Json in .NET 11. This skill tells you exactly
when to reach for each one, what to write, what not to write, and how to prove the
result runs. Do not describe these APIs to the user — apply them, then run the code and
show the output.
| API | Replaces the pre-.NET-11 workaround of... |
|---|---|
JsonNamingPolicy.PascalCase (static property) |
writing a custom JsonNamingPolicy subclass or hand-annotating every member with [JsonPropertyName] |

calling non-generic GetTypeInfo(typeof(T)) and casting to JsonTypeInfo<T> |
JsonSerializerOptions.TryGetTypeInfo<T>(out JsonTypeInfo<T>? info) |
wrapping GetTypeInfo in try/catch to probe availability |
Step 0 — Make the requested net11.0 validation possible
These APIs only exist in the .NET 11 base class library. Before writing code:
