Question

在使用<#@ assembly #>指令的T4模板引用的程序集中，我执行代码var dte = (EnvDTE.DTE)serviceProvider.GetService(typeof(EnvDTE.DTE));，这会导致以下异常和堆栈跟踪。

Error   1   Running transformation: System.IO.FileNotFoundException: Could not load file or assembly 'MyProjectName.TextTemplating, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.

在引用的程序集中，通过项目的程序集属性或直接在使用属性[assembly: ComVisible(..)]的AssemblyInfo代码文件中切换ComVisible程序集属性似乎可以解决异常。

如何在T4模板引用的程序集中获取EnvDte.DTE
