新的ASP.NET MVC 3项目错误

Question

我创建了一个全新的ASP.NET MVC 3项目，并且在不做任何更改的情况下运行它以观察项目模板行为，并且我收到“Method not found error”下面是完整的堆栈跟踪。

当我在对象浏览器中查看WebPageContext对象时，我发现确实没有匹配调用构造函数的方法签名。 System.Web.WebPages参考解析为C：\ Program Files（x86）\ Microsoft ASP.NET \ ASP.NET Web Pages \ v1.0 \ Assemblies \ System.Web.WebPages.dll。

我试图重新安装ASP.NET MVC 3 RTM以及VS 2010 SP1，但没有运气。请帮忙。

Answer 1

问题出在Visual Studio异步CTP安装。显然SP1不喜欢Async CTP。

我卸载了Visual Studio 2010 Beta1以及ASP.NET MVC 3以及Visual Studio Async CTP，然后重新安装了Visual Studio 2010 SP1，现在一切正常。

这花了太多时间，可惜这个问题花了整整一天的时间才解决，微软真的应该一起行动起来。

Answer 2

你提到试图重新安装MVC 3 RC。请注意，RC不再受支持。请安装RTM版本并重试。这应该可以解决您的问题。
