错误:找不到此项目类型所基于的应用程序 [英] Error: The application which this project type is based on was not found

问题描述

我安装了VS2012，并试图打开另一个开发人员也使用VS2012开发的项目.但是我收到如下错误消息.我搜索了错误消息，发现大多数MVC项目都存在相同的问题，并找到了解决方案.但是我的不是MVC项目.最初的开发人员说，这是一个Light Switch和Entity Framework项目.我该如何开始排除故障以找出计算机上缺少的内容并解决此问题?

解决方案

错误消息表明您的项目扩展名是 .ls3proj ，这是Visual Studio Lightswitch使用的扩展名.

请确保在安装Visual Studio 2012(或更改/修复)时已选择此产品.

I installed VS2012 and tried to open a project that was developed using VS2012 as well by another developer. But I am getting an error message as below. I googled the error message and found most of MVC projects have same problem and found solutions to those. But mine isn't a MVC project. The original developer said it is a Light Switch and Entity Framework project. How can I start trouble shooting to find out what I am missing on my computer and to solve this problem?

解决方案

The error message indicates that the extension of your project is .ls3proj, which is the extension that Visual Studio Lightswitch uses.

Make sure that when you install Visual Studio 2012 (or when you change/repair), that this product is selected.
