DNX 构建失败 - 从 msbuild.exe 收到意外退出代码：1
DNX Build Failed - Unexpected exit code received from msbuild.exe: 1
我不明白为什么下面的构建失败了。
项目构建成功。
“##[error]从 msbuild.exe 接收到意外退出代码：1”会导致以下输出结果吗？

我删除了项目依赖项，现在可以使用了。我不知道例外意味着什么。发布了关于 .
的问题
我也遇到了这个问题。如果有人遇到类似问题，我将发布此答案，然后尝试此解决方案。我的 visual studio 解决方案具有针对不同版本的 .NET Framework 的项目（一个项目 .NET 4.5.1 和其他项目 .NET 4.5.2）。它还有一个目标平台设置为 Sql Server 2016 的数据库项目。
我必须确保我的解决方案中的所有项目都以 .NET 4.5.2 为目标，并且数据库项目的目标平台设置为 Sql Server 2012。这是因为我们的构建服务器具有不同版本的 Visual studio安装。因此，检查目标框架是否适用于您的项目，以及您是否有数据库项目，然后确保它们针对 Sql 服务器的正确版本。
我不明白为什么下面的构建失败了。
项目构建成功。
