performance and load testing deprecation
Visual Studio 2019 will be the last version of Visual Studio with load test features.
via Visual Studio 2019 Preview Release Notes
As of right now, we have no plans to drop support for Visual Studio multi-step tests, and (although this is not a guarantee), we do not intend to drop support for them without a 1 year lead time, a sufficient replacement, and migration guidance. Visual Studio 2019 will still have the ability to write multi-step tests, and the support lifecycle for a Visual Studio product is 5 years. My recommendation is to continue using Visual Studio multi-step web tests.
