CS0103: The name `Viewbag' does not exist in the current context

When I try to run the website after creating the Index view the following error occurs

System.Web.Compilation.CompilationException CS0103: The name `Viewbag' does not exist in the current context

Description: Error compiling a resource required to service this request. Review your source file and modify it to fix this error.

Full code for index.cshtml is below:

@model ComicBookGallery.Models.ComicBook[]

@{ Viewbag.Title = "Comic Books"; }

<h2>@ViewBag.Title</h2>

<div class="row"> @foreach (var comicBook in Model) { <div class="col-md-3"> <h4>@comicBook.DisplayText</h4> <img src="/Images/@comicBook.CoverImageFileName" alt="@comicBook.DisplayText" class="img-responsive" /> </div> } </div>

I don't understand why Viewbag does not exist in the current context. Any help would be appreciated

Davis,

The name of the property is actually "ViewBag" not "Viewbag". Remember, C# is case-sensitive!

Thanks ~James

Hello James, I actually have the same issue and I am using the proper case. Any suggestions?
