EmbeddedResourceVirtualPathProvider和@ Html.TextBoxFor（LINQ表達式）

Question

在我的.cshtml文件，我得到一個錯誤的地方我用@ Html.TextBoxFor

這裏是一個示例代碼：

@model WebComposite.Models.CompositeModel 

<label for="name">Name</label> 
@Html.TextBoxFor(m => m.name) 

錯誤：

Error #1: 
'System.Web.Mvc.Html.InputExtensions.TextBoxFor<TModel,TProperty>(System.Web.Mvc.HtmlHelper<TModel>, System.Linq.Expressions.Expression<System.Func<TModel,TProperty>>)' cannot be inferred from the usage. Try specifying the type arguments explicitly. 

Error #2: 
One or more types required to compile a dynamic expression cannot be found. Are you missing a reference? 

有什麼想法嗎？

Answer 1

想知道，這裏是我如何解決它：

1. right click on the project -> select properties 
2. select Application 
3. change "target framework" (I was at 4.5, so I changed it to 4) 
4. change "target framework" to whatever it was before step 3 

web.config中被清理，適當引用添加，做一個構建，一切都應該恢復正常
