Visual studio extension (VSIX) for automatic code generation using Roslyn

Hi I need a plugin for visual studio extension that will automatically generate template source code based on the current object model as reported by Roslyn. Basically the plugin will sit in the background and monitor the current object model as reported by Roslyn. If it finds any classes derived from class MyClass. It will will generate a new c# file and template class based on the properties defined in MyClass. It will add this template class to the project automatically. It will monitor the save-all button and regenerate the automatically generated source file if there are any changes. Basic specification: Monitor open solution for any classes derived from MyClass If found create a new c# file with .[login to view URL] prefix and add file to project. Create a template class (I can send you a template) and place it in file The template will contain some auto-generated properties based on the typeinfo of the class derived from MyClass
