简单Hello web应用程序错误MSB4019的构建失败:未找到导入的项目

Question

我有一个简单的asp.net web应用程序，它打印Hello。我不是开发人员，我想做的就是在Azure web应用服务上部署一个web应用程序。源代码在github上，当它试图通过github操作进行构建(用dotnet构建)时，我会得到以下错误。

我已经做了一些研究，很多用户建议修改csproj文件，这是我没有的核心技术是使用visual。

我找到了链接https://alastaircrabtree.com/microsoft-webapplication-targets-was-not-found-again/，它应该是一个解决问题的黑客，但是在对下面的行做任何更改之前，我想在这里检查是否有人知道这里发生了什么。

我更改了以下几行

<!-- <VSToolsPath Condition="'$(VSToolsPath)' == ''">$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)</VSToolsPath> -->
<VSToolsPath Condition="'$(VSToolsPath)' == ''">$(MSBuildProgramFiles32)\MSBuild\Microsoft\VisualStudio\v14.0</VSToolsPath>

本质上，您的csproj中的Microsoft.WebApplication.targets路径无法在磁盘上找到。你的解决办法看上去很管用。

或者您可以尝试添加：

<Import Project="$(VSToolsPath)\WebApplications\Microsoft.WebApplication.targets" Condition="'$(VSToolsPath)' != '' And Exists('$(VSToolsPath)\WebApplications\Microsoft.WebApplication.targets')" />
