Removing support for .NET 5.0 in the Google Ads API client library for .NET

Starting with version 19.0.0, the Google Ads API client library for .NET requires .NET version 6.0 or higher. Support for .NET Framework remains unchanged and the minimum required version remains 4.7.2.

Version 18.1.0 of the Google Ads API client library for .NET, which adds support for the Google Ads API v16, will be the last version that supports .NET version 5.0. We will still fix security issues for this client library version until the Google Ads API v16 is sunset in January 2025, but no new features will be added.

.NET version 5.0 reached its end of life in May 2022. Microsoft no longer provides security fixes for this version, so we strongly recommend migrating to newer versions as soon as possible.

The Google Ads API client library for .NET already supports newer LTS versions like .NET 6.0 and 8.0, and we plan to support forthcoming LTS versions as well.

Here are some useful resources to help with the .NET upgrade:
