Question

在打开VS 2010之后，我创建了一个空的MVC 4 Web应用程序'UmbracoTest'以及一个新的解决方案。 View引擎是Razor和.Net 4.在Package Manager控制台中，我输入了PM＆gt; install-package umbracocms并提示：

Answer 1

如错误所示：You are trying to install this package into a project that targets '.NETFramework,Version=v4.0'。 Umbraco依赖于ASP.NET MVC 5，它不适用于.NET 4.0。实际上，VS2010不支持.NET 4.5。相反，您将需要Visual Studio 2012或更高版本。

如果您是学生，开源开发人员或个人开发人员，则可以使用免费社区版download of Visual Studio。

无法通过Visual Studio 2010中的Nuget / Package Manager安装umbraco 7.5.4
