我最近通過在MVC4中創建新的Web應用程序並將所有文件複製過來,最後合併web.config中。所有這些都適用於現有的Web應用程序,但是我今天剛剛注意到一個非常奇怪的錯誤 - 如果我嘗試使用默認的虛擬實現創建一個新的API控制器,然後瀏覽到該API(例如/ api/events),我收到一個Could not load type
錯誤。奇怪的是,如果我重建應用程序,並再次命中URL,它似乎是一個不同的組件,它的抱怨,主要是它交替這兩個之間:手動將MVC Web應用程序從3升級到4,無法添加API控制器
Could not load type 'System.Web.Razor.Parser.SyntaxTree.CodeSpan' from assembly 'System.Web.Razor, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.
和
Could not load file or assembly 'Microsoft.Scripting, Version=1.1.0.20, Culture=neutral, PublicKeyToken=7f709c5b713576e1' or one of its dependencies. The system cannot find the file specified.
我web.config中包含以下組件綁定信息:
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" />
<bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="2.0.0.0" />
</dependentAssembly>

<bindingRedirect oldVersion="0.0.0.0-2.0.0.0" newVersion="2.0.0.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>
而且我packages.config看起來像它擁有所有的權利位是:
<package id="AspNetMvc" version="4.0.20126.16343" />
<package id="AspNetRazor.Core" version="2.0.20126.16343" />
<package id="AspNetWebApi" version="4.0.20126.16343" />
<package id="AspNetWebApi.Core" version="4.0.20126.16343" />

<package id="Microsoft.Web.Optimization" version="1.0.0-beta" />

<package id="System.Web.Providers" version="1.1" />
<package id="System.Web.Providers.Core" version="1.0" />
我甚至從一個新的mvc4 Web應用程序,它仍然給了我同樣的錯誤(無法加載文件或程序集Microsoft.Scripting)
試圖複製了我的web.config以「香草」一個
你有一個名爲Microsoft.Scripting組件,不是嗎?你是否在命名空間System.Web.Razor.Parser.SyntaxTree中有一個CodeSpan類? – 2012-04-20 16:20:47
