當T4使用DTE打開生成的文件時，Visual Studio序列化錯誤

我們有一個名爲GenerateProxies.tt的C＃T4文件，它調用幾個命令行codegen實用程序。使用System.Diagnostics Process類，我們將標準輸出重定向到T4輸出文本文件（GenerateProxies.txt），以便我們可以查看命令行輸出的錯誤。當T4使用DTE打開生成的文件時，Visual Studio序列化錯誤

我將以下簡單代碼添加到T4的末尾，以便Visual Studio將打開生成的文本文件作爲該流程中的最後一步（workingDirectory變量已在模板中更早的聲明和填充）。這確實有效，但會引發序列化錯誤。這個錯誤可以避免嗎？

<#@ assembly name="EnvDTE" #> 
<#@ import namespace="EnvDTE" #> 
<# 
    IServiceProvider vssp = (IServiceProvider)this.Host; 
    DTE dte = vssp.GetService(typeof(DTE)) as DTE; 
    dte.ItemOperations.OpenFile(
     string.Format(@"{0}\GenerateProxies.txt", workingDirectory), 
     Constants.vsViewKindTextView 
    ); 
#>

同樣，這確實工作，它會打開文本文件，但它會產生這個錯誤：

Running transformation: System.Runtime.Serialization.SerializationException: 
Type 'Microsoft.VisualStudio.Platform.WindowManagement.DTE.WindowBase' in 
Assembly 'Microsoft.VisualStudio.Platform.WindowManagement' 
is not marked as serializable.

調用堆棧可能幫助。 – Will

是的，但不幸的是它來自開發虛擬機，根本沒有外部訪問（這就是爲什麼我不打算重新鍵入所有程序集信息，關鍵GUID等）。調用堆棧很大，但它看起來像某種PInvoke編組問題。顯然DTE是COM。我隱約懷疑這是一個線程問題。 – McGuireV10

像我這樣的氣味偶然被跨AppDomain邊界拉過來。調用堆棧可以識別源，並且您可以在堆棧中的代碼底部調查誰擁有對該類型實例的引用。 – Will

這不是一個答案然而由於要求的OP不能提供堆棧跟蹤在評論中。

我有一個類似的異常被拋出時，我嘗試在我的TT文件來執行的功能寫入輸出窗口（ST是評論太長）

private void WriteToOutput(string output) 
{ 
     if (_host == null) 
     throw new Exception("Host property returned unexpected value (null)"); 

     EnvDTE.DTE dte = (EnvDTE.DTE)_host.GetService(typeof(EnvDTE.DTE)); 

     if (dte == null) 
     throw new Exception("Unable to retrieve DTE"); 

     Window window = dte.Windows.Item(EnvDTE.Constants.vsWindowKindOutput); 
     window.Activate(); 

     var outputWindow = (EnvDTE.OutputWindow) window.Object; 
     outputWindow.ActivePane.Activate(); 

     outputWindow.ActivePane.OutputString(output); 
     outputWindow.ActivePane.OutputString("\n"); 
    }
