A service interface is a component of a Visual Studio project. For these tutorials, you'll create one Visual Studio Solution to contain your IMTK projects – one for each tutorial.
Visual Studio opens the Solution Explorer for the IMTKTutorials solution, showing the IMTKTutorials project. Because each service interface created in a tutorial uses a different enterprise server, and enterprise servers are associated at the project level, each service interface must be in its own project. Therefore, we will not use the default IMTKTutorials project but instead will create a separate project within the IMTKTutorials Solution for each tutorial.
