如何在由T4模板引用的程序集中獲取EnvDte.DTE

在使用<#@ assembly #>指令由T4模板引用的程序集中，我執行代碼var dte = (EnvDTE.DTE)serviceProvider.GetService(typeof(EnvDTE.DTE));，這會導致以下異常和堆棧跟蹤。如何在由T4模板引用的程序集中獲取EnvDte.DTE

在所涉及的組件切換的標記有ComVisible特性組件既可以通過項目的組件屬性或直接使用屬性[assembly: ComVisible(..)]中的AssemblyInfo代碼文件屬性似乎解決異常。

我認爲EnvDTE不是GAC的一部分，所以我寧願檢查它是否被部署到正確的位置（無論您在哪裏運行應用程序），而不是用ComVisible來擺弄。 –

@CsabaToth，切換的屬性是由T4模板引用的程序集，而不是用於Visual Studio一部分的EnvDTE。這是一個奇怪的行爲，因爲問題只是通過切換這個屬性而消失。 –

感謝您的信息，有趣。 –
