• Visual Studio Extension which converts C# SYNTAX to Typescript SYNTAX, you just need to Copy C# code, and paste into Typescript.ts source code.

• There is option which will convert class/struct to Typescript interface. (In VS 2015 goto Tool->Option->Typescript Paste-> Convert to interface:true)

HOW TO DEBUG/RUN.

Need Visual Studio 2015 + install VS 2015 SDK to compile and run this extension.
Then you need to configure project to allow you debug with VS 2015: go to project Property, Debug tab ->

• Select Start External Program, and fill your VS2015 path (example: C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\devenv.exe)

BRIEF CODE INFORMATION

Almost all converting classes are in folder Translation, which for each file containing the convert method to convert one kind of syntax (C#) to Typescript. For example ClassDeclarationSyntax in Roslyn will be ClassDeclarationTranslation in this project.

Let say you want convert :
in C#: class A {}
typescript: class myA{}

you just need to navigate to class ClassDeclarationTranslation in project, then change this line:

 return $@"{GetAttributeList()}export class {Syntax.Identifier}{TypeParameterList?.Translate()} {baseTranslation}
           {{
           {Members.Translate()} 
           }}";

to:

 return $@"{GetAttributeList()}export class my{Syntax.Identifier}{TypeParameterList?.Translate()} {baseTranslation}
           {{
           {Members.Translate()} 
           }}";

For more information about Syntax Tree in Roslyn, you can use Syntax Visualizer which is included in VS 2015 (View -> Other Windows-> Syntax Visualizer).
