SpecFlow Visual Studio extension attempted to use

Question

I am getting the following error while trying to build my automation solution. Due to which i am unable to change anything in my feature file at the moment.

error Version conflict - SpecFlow Visual Studio extension attempted to use SpecFlow code-behind generator 1.9, but project 'POC.Specs' references SpecFlow 2.0.

error We recommend migrating to MSBuild code-behind generation to resolve this issue.

error For more information see https://specflow.org/documentation/Generate-Tests-from-MsBuild/

.net version 4.6.2 Specflow 2.0.0 TestStack White Visual Studio 2015

I have tried reinstalling specflow 2.0.0 but still the same issue persists

Any help would be really appreciated.

Answer 1

This issue did my head in. Basically the fix was simple. My specflow extention was modified to specflow 3.0 changes and this issue that I was getting was for a project on specflow 2.4.1 The steps that I did to fix was simple.

1. Reverted back the changes done to specflow extension. Eg: Tools->options->specflow and reverted back Enable Specflowsinglefilegenrator to True
2. Cleared Nuget cache.
3. Deleted the package folder.
4. Upgraded/Freshly installed Nunit latest.
5. Upgraded/Freshly installed Nunit3TestAdapter. Spet 4 was the most important step.

The following steps resolved the issue for me:-

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.(go to the file properties and delete the value for custom tool)
3. Select Tools | Options | SpecFlow from the menu in Visual Studio, and set Enable SpecFlowSingleFileGenerator CustomTool to "false".

Try Step 3 first to resolve the problem. If that doesnt do the trick, go from Step 1 onwards.

Clear the error message in .cs file under the feature file and then rebuild the code
