TF215097: 为构建定义初始化构建时出错

Question

我在 TFS 中构建工作流时遇到如下错误

TF215097: An error occurred while initializing a build for build definition  
Exception Message: Cannot create unknown type '{clr-namespace:Test.Activity;assembly=Test.Activity}GenerateAssemblyVersion'. (type  XamlObjectWriterException)

我已经尝试了http://blog.ehn.nu/2011/12/tfs-2010-build-troubleshooting-the-tf215097-error/ 中指定的所有方法。但我仍然在犯同样的错误

当我在我的自定义任务中使用以下代码时，我也能够找出问题正在发生

public sealed class Myclass: BaseCodeActivity
{
    protected override void InternalExecute()
    {
    }
  }

如果我使用下面的代码能够成功构建。

public sealed class Myclass: CodeActivity
{
    protected override void Execute(CodeActivityContext context)
    {
    }
}

我能够在本地机器上成功构建上述两个代码。

BuildCodeActivity 类派生自命名空间 TfsBuildExtensions.Activities。所以我将所有依赖于此类的 dll 添加到我的 dll 所在的根文件夹中，包括 TfsBuildExtensions.Activities

我不知道为什么 BuildCodeActivity 类会抛出这个错误

1. 请提供有关您的环境以及您所做的工作的更多信息。
2. 创建一个新的构建定义并将构建排队，看看您是否可以重现此问题。
3. 创建一个轻量级项目并排队构建，看看您是否会重现此问题。
4. 创建一个新的构建代理，看看您是否会重现此问题。
