I've created a .NET Core project and I'm using VSCode on Linux. I installed SpecFlow with dotnet add package SpecFlow but I don't think there is IDE integration yet. Can I use the SpecFlow nuget package from the command line to create a test?
SpecFlow 3.0 will have .NET Core support. A preview is currently available.
See blog post: https://specflow.org/2018/specflow-3-public-preview-now-available/
To generate the code-behind files we are using the MSBuild generation always for .NET Core. https://specflow.org/2019/generating-code-behind-files-using-msbuild/
