I am using Visual Studio 2010 running on Windows 7 X64 I was trying to create a simple implementation of WCF bidirectional communication. Sorry, I got stuck really fast.
I have 3 projects: - Service library with a simple service contract and implementation - ServiceHost: Hosting a service library through SelfHosting - Client: using a method from the WCF service
Something I immediately noticed that the Service library had any processor as a platform. The other two had x86 as a platform. At the moment, I had no idea that I would get this error, so it really didn't bother me.
Then I launched the services library using the built-in wcfsvchost.exe. The service was hosted without problems. Then I wanted to host my service through my own host. Here I got my first experience with System.BadImageFormatException. I had no idea what it was at that moment. So I got stuck and made some kind of search engine. If I understand correctly, the platform of all DLLs, etc. Must be the same. if someone can explain me a little better. Please do.
In any case, that’s why I would change the service library platform because it had any processor instead of x86. So I tried to do this using Project settings and configuration manager. But the problem is that I did not have the opportunity to change it. Then I unloaded the project, looked at what another .csproj looked like, and changed the values there. Rebooted it, and everything was in order. Now he had the right platform, x86. So let the test run the service library. BOOM System.BadImageFormatException
