Will there be problems with using EnvDTE.DTE inside tt?

[silentnightwalk]

Is it possible to do the same when tt contains

var visualStudio = (this.Host as IServiceProvider).GetService(typeof(EnvDTE.DTE)) as EnvDTE.DTE;

?

I'm afraid to get null reference exception. Your method looks like running TextTransform.exe by self. However, I also tried to run TextTransform.exe from batch file and got this exception.
