新的ASP.NET MVC 3項目錯誤

Question

我創建了一個全新的ASP.NET MVC 3項目，並且在不做任何更改的情況下運行它以觀察項目模板行爲，並且我收到「Method not found error」下面是完整的堆棧跟蹤。

當我在對象瀏覽器中查看WebPageContext對象時，我發現確實沒有匹配調用構造函數的方法簽名。 System.Web.WebPages參考解析爲C：\ Program Files（x86）\ Microsoft ASP.NET \ ASP.NET Web Pages \ v1.0 \ Assemblies \ System.Web.WebPages.dll。

我試圖重新安裝ASP.NET MVC 3 RTM以及VS 2010 SP1，但沒有運氣。請幫忙。

Answer 1

問題出在Visual Studio異步CTP安裝。顯然SP1不喜歡Async CTP。

我卸載了Visual Studio 2010 Beta1以及ASP.NET MVC 3以及Visual Studio Async CTP，然後重新安裝了Visual Studio 2010 SP1，現在一切正常。

這花了太多時間，可惜這個問題花了整整一天的時間才解決，微軟真的應該一起行動起來。

你提到試圖重新安裝MVC 3 RC。請注意，RC不再受支持。請安裝RTM版本並重試。這應該可以解決您的問題。
