Issue Description

When I edit the feature file the cs file generated behind contains:

#error Could not find a reference to SpecFlow in project ''. #error Please add the 'TechTalk.SpecFlow' package to the project and use MSBuild generation instead of using SpecFlowSingleFileGenerator. #error For more information see https://specflow.org/documentation/Generate-Tests-from-MsBuild/

I have to build the project manually to generate proper test file. Do know this issue?

Did you follow the link?

[Planche95]

Yes, I have SpecFlow.Tools.MsBuild.Generation nuget package installed and SpecFlowSingleFileGenerator removed from properties

@Planche95 are you sure you removed all of them and did a build? In the build the code-behind files are regenerated and the #error messages should go away.

[Planche95]

@SabotageAndi if I run the build the files are regenerated properly. My issue is that if I made changes to a features (without build), i get this error's instead of properly generated tests, and because of that my specflow test's dissapear from my Test Explorer and I lost all information about my previous test run
