Description

It seems that setting this property to null or an empty string removes the content type header, instead of throwing the documented exceptions.

Exceptions
ArgumentNullException

The value specified for a set operation is null.
ArgumentException

The value specified for a set operation is an empty string ("").

As the implementation actually provides useful behavior, I'm in favor of updating the documentation.

See the original source: https://github.com/dotnet/runtime/blob/main/src/libraries/System.Net.HttpListener/src/System/Net/HttpListenerResponse.cs#L36

      public string? ContentType
       {
           get => Headers[HttpKnownHeaderNames.ContentType];
           set
           {
               CheckDisposed();
               if (string.IsNullOrEmpty(value))
               {
                   Headers.Remove(HttpKnownHeaderNames.ContentType);
               }
               else
               {
                   Headers.Set(HttpKnownHeaderNames.ContentType, value);
               }
           }
       }
