Hi Sadik,
Thank you for raising this concern to the Google Ads API Forum
With regard to your concern, could you confirm if you are using the latest .NET
library version >= 12.1.0 according to this document? If yes and the issue
still persists, you may reach out to the .NET client library owner
Same code is working with version 10.0 but yesterday i updated to version
11.0 after that i'm getting below error
"Method not found: 'Void
Google.Api.Gax.Grpc.ClientHelper..ctor(Google.Api.Gax.Grpc.ServiceSettingsBase)'."
GoogleAdsClient client = new GoogleAdsClient();
