Question

I have a WCF service that is hosted on a c# console application. Is there a way to restart this service, preferably by calling an endpoint in the service itself (ex. myService.Restart()).

Thanks

Answer 1

To answer my question, I have solved the problem by doing the following:

• Separating the code that loads the DLL files from the WCF service code into another class library project
• Create an interface with the same method signatures as the ones that load DLL files in the new project (this interface is used by both projects now)
• In the web service, load the other project in a new application domain. This way the DLL files are locked by the new application domain not the default.

If I want to update my nunit DLL files now, all I have to do is unload the application domain from the web service, update the files and finally create a new application domain.

AppDomain remoteDomain = AppDomain.CreateDomain("New Domain");
IClass1 class1 = (IClass1)remoteDomain.CreateInstanceFromAndUnwrap(
                           "Test1.dll", "Test1.Class1");

Note: IClass1 is the common interface between the projects.
