When I make changes in Specflow feature file, its not updating feature.cs file automatically and getting an error [Specflow] System.Unauthorized.Access.Exception
I am using Specflow version 3.1.97 in Visual studio 2019 and below is the configuration of Specflow extension
Since SpecFlow 3, you can't anymore use the SpecFlowSingleFileGenerator.
You have to use the MSBuild integration to generate the code-behind files.
But this is easy. You have simply to add the SpecFlow.Tools.MSBuild.Generation
NuGet package to your project.
If you still have configured a custom tool for your feature files, you have to remove this.
You can find more information here: https://docs.specflow.org/projects/specflow/en/latest/Tools/Generate-Tests-From-MsBuild.html
