Debug a Windows Service with WCF library

hop of those help? So I guess it's time to admit my stupidity.... :P
It turns out this was not a python issue, py2exe issue, nor a WMI issue. :(

this will help There are a couple ways you could do this.
One way would be that I would create a console application project, and reference the exe of the service project(same way you would reference a DLL). Create a mock JobExecutionContext and call Execute from the Console application. Configure Visual Studio to startup both the WCF service and the mock Console Application: In Solution Explorer, right-click the solution name. Click Set Startup Projects. In the Solution Properties dialog box, select Multiple Startup Projects.

around this issue Okay the error was way away from where I thought it was the error was it was running on my user interface thread so needed to add.

I wish this help you OK, here is what I found.
Creating a new solution with one Windows service project with a Wcf service class and one Asp.Net folder. Running the Windows service. Trying to add a Service reference to the Asp.Net project.

Any of those help After long-long-long investigation my colleague found the root cause and how to fix it (to work it around if to be more precise).
It appeared that in such condition Bug1400637 happens and to work it around in Firefox v57.0 it requires to set security.sandbox.content.level to 4 in about:config.
