Hi Trevor, Thanks for explaining your scenario. It seems that this issue is more on the .NET client library as you mentioned that the C# object has adServingOptimizationStatusSpecified field which is set to true automatically, and this makes your request fail since if you are updating a field in your campaign, you are not supposed to include the adServingOptimizationStatus field. You can post this concern here <https://github.com/googleads/googleads-dotnet-lib/issues> as the library owners can provide further assistance in regards to this.
Also, if your main goal is to update different fields in your campaign, I recommend that you only include the fields that you wish to update so the request won't fail. You can refer to this example <https://developers.google.com/adwords/api/docs/samples/csharp/basic-operations#update-a-campaign> which includes the fields that can be updated.
