不受支持的上下文键入mvc [英] UnSupported Context Type in mvc

问题描述

大家好，



我在我的系统中安装了mvc。使用Model First和Entity Framework 4.1。当我创建控制器时，它显示错误消息不支持的上下文类型。我在谷歌搜索但我没有找到实际的解决方案。是我的安装问题还是问题..



我认为有关实体框架版本的问题。我的操作系统是xp.so我们添加了额外的powershellpackage来运行mvc

当我尝试安装mvcscaffolding时显示如下信息..

安装-Package MvcScaffolding 
试图解决依赖'T4Scaffolding'。 
尝试解析依赖关系'EntityFramework（≥4.1.10311.0）'。 
您正在从Microsoft下载EntityFramework，其许可协议可从http://go.microsoft.com/fwlink/?LinkId=224682获取。检查软件包是否有其他依赖关系，这可能与他们自己的许可协议一起提供。您对软件包和依赖项的使用即表示您接受其许可协议。如果您不接受许可协议，请从设备中删除相关组件。 
已成功安装'EntityFramework 4.1.10715.0'。 
成功安装'T4Scaffolding 1.0.5'。 
成功安装'MvcScaffolding 1.0.6'。 
从MvcApplication2成功删除了'EntityFramework 4.1.10331.0'。 
成功将'EntityFramework 4.1.10715.0'添加到MvcApplication2。 
成功将T4Scaffolding 1.0.5添加到MvcApplication2。 
成功将MvcScaffolding 1.0.6添加到MvcApplication2。 
成功卸载'EntityFramework 4.1.10331.0'。

并且当试图添加控制器时，错误不支持的上下文类型是显示。





期待您的回复..





谢谢，
