#59
Add a virtual BuildClassDeclaration method to CSharpCodeBuilder.

This extensibility point needs to be an override and not a pure visitor due to how the class declaration is created (only 1 right way to write the class).

#76
Fixed build break due to adding configurations
Renamed configurations to frameworks in project.json
Reacting to System.Collections version change
Updating release Nuget.config
