I’m getting an BC30203: Identifier expected error in my ASP.NET MVC 4 project. I have zero idea why this is happening and I’m getting extremely frustrated. I have no idea where the error is (besides the class).

I hadn’t even touched the page for days (last time it was working) and now I get the error. Clearing temp files, .NET Framework temp files don’t help either, restarting, reinstalling VS. I even switched from 2010 to 2012RC with no luck. I’m at a complete loss.

I’ve removed more and more code and it seems to happen whenever I declare a variable. It is not my models or anything else as they work 100%, just not in this one page.

Here is the code from the partial view:

@ModelType Frontend.Models.Collection 

@Code
    ViewData("Title") = "GetFilters"
End Code

@AddSeparator("Options")
@Options

@Helper Options()   

    Dim less As String=String.Empty
    @<div class="ui-splitbutton filter">
        <a class="@less" href="#" title="Show only basic filters" rel="nofollow">Show less</a>
        <a class="" href="#" title="Show all available filters" rel="nofollow">Show more</a> 
    </div>

    @<div>
        <a class="button clear_filters filter" href="#" title="Remove all applied filters" rel="nofollow">Clear filters</a>
     </div>

End Helper

@Helper AddSeparator(text As String)                                               
    @<div class="separator">
        <span>@text</span>
    </div>
End Helper

Here is how I render the page:

@Code
    Html.RenderPartial("_PartialFilters", Model)
End code

And here is the exception:

System.Web.HttpCompileException was unhandled by user code
  ErrorCode=-2147467259

For anyone else who this happens to and cannot fix…

For me, inside the partial page I was creating a lot of dropdowns and other controls. I made a helper for this and moved the bulk of the code to a @Function helper and use the TagBuilder.

I don’t think it is a cheap workaround – too much. I still don’t have any idea of the root cause.
