AlliedModders - SharpSource

SharpSource

Short description:
SharpSource is a SourceMod extension which enables the developer to create extensions in C#. Like adding new native functions while using C#.

Status report:
This extension is currently in an early development stage, while the code is already available in order to encourage other people to participate in the development, binaries will be shipped when the extension will provide more functionality.

Currently the plugin loads managed (C#) code and loads managed assemblies, note how the arguments are all marshalled.

TODO:

Adjust and compliment (with helper functions) the exposed C++ interfaces for easy access
Create a safe subplugin system
Add IronRuby support
Add IronPython support

DONE:

Access C++ interfaces from within C#
Generate C++ wrapper classes with gccxml/a C# generator
Support native function creation

Credits:
The CXXI Project - an awesome C++ bindings generator for C#
Bailoplan for such a great project

Code is available at github

Some of the interfaces available in the C++ world are now available in the C# world.
I am continuing to add more and more, but I have to adjust them to make the look as native as possible.
A lot of the code is autogenerated, but the generated code needs a lot of adjustments.

Adding native functions from the C# world looks already quite awesome and easy to do:
