google-api-dotnet-client - Google APIs Client Library for .NET
If you're working with Google Cloud Platform APIs such as Datastore or Pub/Sub, consider using the Cloud Client Libraries for .NET instead. These are the new and idiomatic .NET libraries targeted specifically at Google Cloud Platform Services. This client library is supported but in maintenance mode only. We are fixing necessary bugs and adding essential features to ensure this library continues to meet your needs for accessing Google APIs. Non-critical issues will be closed. Any issue may be reopened if it is causing ongoing problems.
