我有一个 Dynamics365 DevVM 并将其从 10PU26 更新到 10PU28，以便我在与我正在开发的系统相同的平台版本上进行开发。应用 10pu28 后，我启动了我的 VisualStudio，更改了一些内容并尝试保存和编译，但注意到 BP 已损坏，因此我无法进一步开发。Visual Studio 记录以下内容，但我不确定我能做些什么来解决这个问题。

Build step: Best practice check completed (9 ms).
Build completed (716 ms).

作为临时解决方法，我尝试在构建时禁用正在运行的 BP，但这也不起作用。当 BP 被禁用时，我仍然无法编译。以下是日志：

如果更新未成功更新所有组件，则可能会导致此问题。如果使用默认拓扑文件进行更新，则可能会导致此问题。Microsoft的文档在更新过程的这一部分有点混乱（请参阅问题 1137）。确保根据文档中的收集拓扑配置数据部分更改拓扑文件。

我还建议查看d365fo.tools，其中包括函数Invoke-D365SDPInstall，它在升级过程中为您完成了大量工作（包括拓扑文件的更新）。
