Compile typescript file from t4 template

Question

I have created a t4 template which creates typescript dto files based on my c# dtos. During the generation I also want to compile the produced ts files into js files and add them to the solution, just like web essentials does for me when I save a ts file.

My initial thought was to somehow trigger the save event;

EnvDTE.DTE dte = (EnvDTE.DTE) ((IServiceProvider) this.Host).GetService(typeof(EnvDTE.DTE));
dte.OpenFile(EnvDTE.Constants.vsViewKindAny, outputFilePath);

Save the file (to trigger the compile) and then close it again. But I can not get this to work.

Does anyone have an idea for me?

I ended up doing as proposed by Ryan Cavanaugh and just invoking the compiler. I used Olegs tips for creating more than one output for a template to add the generated files to the project and tt template.

I kicked off the compiler by the following code:

<#+ 
void CompileTypeScriptFile(string fullFileName)
{
    var process = new System.Diagnostics.Process
    {
        StartInfo = new ProcessStartInfo
        {
            FileName = "tsc.exe",
            Arguments = "--target ES5 \"" + fullFileName + "\""

        }
    };
    process.Start();
    process.WaitForExit();
}
