Other 2xx codes
All HTTP status codes in ASP.NET Core

StatusCode(StatusCodes.Status202Accepted)
Problem(statusCode: StatusCodes.Status202Accepted, detail: "...")Checked on Kestrel: Results.Accepted(uri) returns 202.
The ProblemDetails body
What Results.Problem(statusCode: 202) sends (with AddProblemDetails()), as application/problem+json:
{
"title": "Accepted",
"status": 202,
"traceId": "0HNA1B2C3D4E5:00000001"
}A controller's Problem(statusCode: 202) sends a different body, because MVC only fills type and title for codes in ApiBehaviorOptions.ClientErrorMapping:
{
"status": 202,
"traceId": "0HNA1B2C3D4E5:00000001"
