TFS 不加载自定义程序集

Question

我在尝试让构建控制器/代理从构建过程模板中使用的参考中获取自定义程序集时遇到问题。

我已经在多个博客中广泛阅读过这个问题，但很遗憾我无法解决这个问题：

我可以确认以下几点：

1. 没有更新的 TFS 2012 Visual Studio 2013，更新 1（创建 活动并升级构建过程模板）

2. 一个带有多个代理的构建控制器

3. TFS 程序集签入并在源代码控制中

在构建控制器中设置正确的路径并重新启动服务：

按照这些博客中使用的指南，自定义活动在模板中正确解析：

我可以查看构建过程模板的 XAML 中的引用，它看起来很好，没有验证错误，而且我的代码活动似乎已正确实现。

代码如下：

Answer 1

您是否重新启动了机器？尝试清除构建机器上的缓存

C:\Users\ BUILDACCOUNT\AppData\Local\Temp\BuildController\2.0\Assemblies

C:\Users\ BUILDACCOUNT\AppData\Local\Temp\BuildAgent\ BUILDAGENTNO\Assemblies

任何一种方式都应该强制构建控制器下载最新的程序集

Answer 2

最后，通过使用 TFS 2013 和最新的服务包解决了这个问题。现在加载自定义程序集没有问题。
