.NET 9 / Carter / MemoryPack / IResponseNegotiator example
Open app.http and run the examples.
GET / returns a regular Carter negotiated result but will throw an exception.
GET /result will convert the Carter negotiated result to an IResult and avoid the exception.
Cause of the exception https://github.com/dotnet/aspnetcore/blob/1770dcf4e81872395cc4d3b3b3efbaef91f8020a/src/Shared/RouteHandlers/ExecuteHandlerHelper.cs#L27
