For SpecFlow 3 you have to use the MSBuild generation.

To this, follow these two steps:

1. Add the NuGet package SpecFlow.Tools.MsBuild.Generation with the same version as SpecFlow to your project
2. Remove all SpecFlowSingleFileGenerator custom tool entries from your feature files.

Background what is happening:

The VS Extension has sometimes problems to find the used SpecFlow version. In that case, it falls back to the SpecFlow version shipped with the extension (which is really old). This version is generating code with now not existing NUnit attributes.
