C# Класс T4Scaffolding.Core.ProjectTypeLocators.EnvDTETypeLocator

Gets the type only if typeName is its fully-qualified name and it's local to the specified project

Recursively scan to extract all CodeType elements. But since the CodeModel contains *all* referenced types (including the whole of System.*), it would be too slow to consider them all. We're only interested in types defined in the project itself, so we disregard namespaces that contain one or more type with InfoLocation != vsCMInfoLocation.vsCMInfoLocationProject

Picks out the referenced projects that are defined in your solution (i.e., are not external assemblies) by discarding references without a SourceProject

Out of a set of CodeType instances, some of them may be different partials of the same class. This method filters down such a set so that you get only one partial per class.
