Support generic types

[michaelaird]

Rosetta should support generic types. Generic types can be used for fields, properties, variables, class types and base class types.

I spent a while poking at implementing this and going in circles.

Here are some issues/thoughts:

• GenericNameSyntax inherits from SimpleNameSyntax so it should be straightforward to differentiate between them and handle them separately
• The list of type arguments are also TypeSyntax nodes so they need to be walked recursively
• TypeReference is a likely candidate for handling generics
  • There are 2 TypeReference helpers, one specifically for BaseTypes of classes. They both need to handle generics properly
• Currently, type name mapping from C# to TypeScript is taking place outside of TypeReference ( in TypeMappings.MapType which only accepts a string)
  • Many type checks are being done using String.Contains. This could lead odd errors. (eg. a user defined type named UnavoidableIncident would be treated as void )

@andry-tino I'm not sure where to go with this right now so let me know what you think.

Hello and sorry for the long wait. I am pretty busy at the moment, I will get back to you soon! Let me also go through your code and points...

[michaelaird]

No worries. We're continuing to crank through implementing some more things. On our radar:

• Switch statements
• Try/catch blocks
• CastExpression
• ArrayCreationExpression
• ElementAccessExpression
• LogicalAndExpression
• LessThanExpression
• GreaterThanExpression
• ConditionalExpression
• LogicalOrExpression
• AsExpression

Very cool. I have some work I need to prioritize at the moment on the ScriptSharp definition generator. Once done, I will start integrating those changes.

Here's my initial crack at handling generic types(and nullable types, and arrays and some other bits).

Over the weekend, I'm going to try to also put in calling generic methods.

Yes seems a good start. I am finalizing my changes for supporting ScriptSharp TS definition file generation via assembly only. After that I will have more times for integrating your changes.
