在TFS 2010上，当我启动包含自定义活动的构建定义时，我遇到了这个错误：
TF215097: An error occurred while initializing a build for build definition \BCA3\BuildProcessSourcet8: Cannot create unknown type '{clr-namespace:BuildProcessSourcet8.Activities;assembly=Sourcet8}CopyActivity'.
XAML文件的一部分：

我通过在构建计算机中安装相同版本的VisualStudio和TFS客户端解决了该问题。例如，安装VS 2013和TFS 2013，并确保您也使用VS 2013构建自定义dll。
