SharePoint 应用程序部署错误：“无法安装 SharePoint 应用程序”

当我尝试添加 SharePoint mvc 应用程序时，出现以下错误：

Error occurred in deployment step 'Install app for SharePoint': 
Failed to install app for SharePoint. Please see the output window for details.

有人可以解释一下这个问题吗？ :)

这是因为 SharePoint 试图将您的应用程序激活为标准 SharePoint 功能，而实际上它实际上是一个应用程序。

在SharePoint项目的features文件夹中，会有一个名为Feature1的Feature。

打开功能 1 并确保它包含在“解决方案中的项目”列表中，而不是包含在“功能中的项目”列表中。

之后您应该能够部署。
