specflow.exe – ‘libhostpolicy.so’ not found

I’m trying to run the specflow.exe that comes with the nuget package on Linux, but I am getting the below error:

sashoalm@HP:~/.nuget/packages/specflow/2.4.1/tools$ dotnet specflow.exe
A fatal error was encountered. The library 'libhostpolicy.so' required to execute the application was not found in '/home/sashoalm/.nuget/packages/specflow/2.4.1/tools/'.
Failed to run as a self-contained app. If this should be a framework-dependent app, add the /home/sashoalm/.nuget/packages/specflow/2.4.1/tools/specflow.runtimeconfig.json file specifying the appropriate framework.

I found the file:

sashoalm@HP:~$ locate libhostpolicy.so
/usr/share/dotnet/shared/Microsoft.NETCore.App/2.1.7/libhostpolicy.so

How can I make specflow.exe use it?

Answer

SpecFlow <= 2.4 has no .NET Core support, so you can’t execute the specflow.exe with dotnet specflow.exe.
You can try to use Mono to execute it. So it’s mono specflow.exe
