Visual Studio 2015 Update 2 Professional 在架构上崩溃比较

Question

我在解决方案中有一个 SQL Server 项目。我直接在 SQL Server Management Studio 中对数据库进行了一些更新，我想在 Visual Studio 中更新 SQL Server 项目以匹配数据库的架构。在 Visual Studio 中，当我选择“比较架构”并选择数据库作为源和项目目录作为目标，然后单击“比较”时，比较的结果显示在屏幕上，但随后 Visual Studio 立即崩溃。我正在运行安装了 Update 2 的 Visual Studio 2015 Professional，并且我有 Microsoft SQL Server Data Tools 2015。以下详细信息显示在事件查看器中：

Answer 1

尝试清除Visual Studio的缓存：

C:\Users\[user]\AppData\Local\Microsoft\VisualStudio\14.0\ComponentModelCache

删除此目录中的所有内容，然后重新启动 Visual Studio。
