after updating SpecflowRunner to 3.5.8 and re-installing the Specflow Package 2017.2.1 my tests cannot be executed and are skipped instead. When I open the log file I find this Error message:
Error while unpacking executor: System.TypeLoadException: The method "Initialize" in type "TechTalk.SpecRun.Framework.TestAssemblyExecutor" of the assembly "TechTalk.SpecRun.Framework.Executor, Version=1.8.0.0, Culture=neutral, PublicKeyToken=null" is not implemented.
(Sorry, I had to translate the message)
A friend of mine has the same versions, but everything runs smoothly. We both use Visual Studio 2017. Did I miss something, a cache that has to be cleared or anything else?
You have probably some old leftover files from before the update in your obj and bin folder.
After that, you should be able to execute your tests again.
