We also have the same problem with NUnit

I thought I saw a PR for this issue. But now I can't seem to find it any more. Did I hallucinate, or is the PR removed?

Experiencing the same issues sadly

Nope, I saw it too. Would be cool to have a fix, manually searching the bindings is a pain.

Using SpecFlow's VisualStudio extension version 2022.1.91.26832, which pulls in SpecFlow.NUnit version 3.9.40, I cannot duplicate this problem.
Is there a repro project you can post? I'll take a look to at least try to debug the source of the problem. (Can't promise any solutions until the SpecFlow projects gets back up and running).

Hi, I tried these versions without success. But when right clicking on a step and then "Define Steps..." I saw this error:

I will try to setup a mini project that I can share. Maybe I can reproduce the error there.

Browsing through the code I found that this issue is not specflow in general but the VS integration and the issue is tracked here:
SpecFlowOSS/SpecFlow.VS#145

There is also the missing PR ;) SpecFlowOSS/SpecFlow.VS#146

[gasparnagy]

Until it will be published to the marketplace, you can install this version from the VSIX file attached to the release: https://github.com/SpecFlowOSS/SpecFlow.VS/releases/tag/v2022.1.93-net8

[bneumann]

Did that and it works like a charme. I think we can close this here?

[dcdraper]

The new VSIX file works for me too. Thanks @gasparnagy!
