OpenAPI: Enums with JsonStringEnumMemberName are not handled. You have to specifically set [JsonConverter(typeof(StringEnumConverter))]

[niemyjski]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

Enums with JsonStringEnumMemberName are not handled. You have to specifically set [JsonConverter(typeof(StringEnumConverter))]. See StackStatusWithJsonStringEnumMemberName Maybe #59980 ? Either way this should be handled out of the box without needing a converter?

Expected Behavior

These should just work out of the box.

Steps To Reproduce

Clone https://github.com/exceptionless/aspnet-core-net10-issues# and run it, hit the open api json endpoint.

Exceptions (if any)

No response

.NET Version

10 preview 6

I believe this is the default behaviour for System.Text.Json, which Microsoft.AspNetCore.OpenApi is built on top of.

@martincostello Yep, I believe your correct. I couldn't find any code in the JsonSchemaExporter for processing JsonStringEnumMemberNames on their own.

However, I believe this is intentionally behavior of the part of the schema generator, STJ requires that you use [JsonConverter(typeof(StringEnumConverter))] alongisde JsonStringEnumMemberName and the schema exporter is picking up on the TypeInfo generated by the serializer here.
