Test Impact Analysis (TIA) does not work for WCF app when hosted in IIS
You are trying to use Test Impact Analysis on your current project.
The application is an ASP.NET frontend, a presentation layer and a WCF service layer.
You have enabled Test Impact Analysis. But when you change some code in your WCF service layer there are no tests showing in the Test Impact View Window.
Currently this functionally is not implemented for WCF Service hosted in IIS process.
