未安装项目应用程序 [英] the application for project is not installed

问题描述

我正在打开一个显然基于Visual Studio 2003构建的解决方案(不确定，我对此一无所知)，然后尝试迁移到2010.尝试迁移时，我收到消息:

I'm opening a solution that was apparently built on Visual Studio 2003 (not sure, I don't know anything about it) and trying to migrate to 2010. When trying to migrate I get the message:

未安装项目"的应用程序，请确保已安装项目类型(.csproj)的应用程序.

the application for project '' is not installed make sure the application for the project type (.csproj) is installed.

如果我打开解决方案的单个项目中的每个项目，它们都可以正常迁移，但不能迁移解决方案本身.

If I open each one of the single projects of the solution they migrate fine but not the solution itself.

推荐答案

如果您的项目可以正常迁移，则创建一个新的空白Visual Studio 2010解决方案，然后单独添加新项目(右键单击solution-> add-> existing项目)

If your projects individually migrate fine, then create a new blank visual studio 2010 solution, and add new projects individually (right click on solution->add->existing project)

但是我不确定您的项目是否可以单独加载.有些项目类型需要安装一些其他软件才能获得支持.我遇到的最常见的问题是使用旧版本的asp.net mvc(1或2)构建的旧项目，并且我安装了asp.net mvc 3 ...或者实际上是使用asp.net ajax构建的旧项目...在这种情况下，您必须安装该附加软件，然后导入项目，或找到一种工具将该项目类型升级到较新版本.

But I'm not sure that your projects will load fine individually. There are project types that require some additional software to be installed in order to be supported. The most frequent problems I face are old projects built with old versions of asp.net mvc (1 or 2) and I have asp.net mvc 3 installed...or really old projects built with asp.net ajax...In those cases, you have to install that additional software and then import project, or find a tool to upgrade that project type to a newer version.
