The project bindings (e.g. step definitions) could not be discovered.

Used Visual Studio

Visual Studio 2022

Are the latest Visual Studio updates installed?

Yes

SpecFlow Section in app.config or content of specflow.json

Issue Description

I have created an Unit Test Project in visual studio the required references also added to the project level (NUnit, SpecFlow, BaseClass.Contrib.SpecFlow.Selenium.Nunit, SpecRun.Runner,Autofac, Autofac Configuration, SpecFlow.Assist.Dynamic etc.,). after creating a feature file when i try to create step definition by right clicking, it is showing the popup saying all steps are define already Note: it is only happening with the Unit test Project structure.

Steps to Reproduce

1. Create a Unit Test Project
2. Create a feature folder and add the specflow feature file
3. Write the gherkin scenario for the created feature file
4. Install following packages (NUnit, SpecFlow, BaseClass.Contrib.SpecFlow.Selenium.Nunit, SpecRun.Runner,Autofac, Autofac Configuration, SpecFlow.Assist.Dynamic etc.,).
5. Create a step definition file and move it to the step definition folder.
6. save all and build the project.
7. right click on scenario, select Define steps.
8. and issue will arise (all steps are define already)

I have the same situation. This is my log with some personal stuff scrubbed:

I get the same log for each project in the solution. I am not able to navigate to step definitions.

Hi, I have this same issue. Same error. For me - I get this when my specflow project is targeting .net 8.0, but when I switch it back to 7.0 or 6.0 it's fine. Unsure how to get my specflow to work properly with .NET 8. Unless I am missing something?

There is a pre-release version of the extension that is available: https://github.com/SpecFlowOSS/SpecFlow.VS/releases/tag/v2022.1.93-net8

I downloaded and installed it and it is working.

Hi jrbye, thanks so much for responding so quickly. I too can confirm that the pre-release you mention above works for me as well.
