I'm trying something new (to me) in using an abstract base class for my layout viewmodel.
The problem is that when I run the site as is, it throws a very cryptic (to me) exception. What does this exception mean, and what might I do to resolve it?
Layout
@model MyApp.Core.ViewModels.LayoutViewModel
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>@Model.Title</title>
</head>
<body>
<div>
@RenderBody()
</div>
</body>
</html>
Index
@model MyApp.Core.ViewModels.Home.IndexViewModel;
@{
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h1>@Model.Body</h1>
LayoutViewModel
namespace MyApp.Core.ViewModels
{
public abstract class LayoutViewModel
{
public string Title { get; set; }
}
}
IndexViewModel
namespace MyApp.Core.ViewModels.Home
{
public class IndexViewModel : LayoutViewModel
{
public string Body { get; set; }
}
}
Controller
[HttpGet]
public ActionResult Index()
{
var model = new IndexViewModel
{
Title = "Hello World",
Body = "Hello World"
};
return View(model);
}
And the Exception
Compilation Error Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.
Compiler Error Message: CS1003: Syntax error, '>' expected
Source Error:

Compare and contrast:
Layout
@model MyApp.Core.ViewModels.LayoutViewModel
Index
@model MyApp.Core.ViewModels.Home.IndexViewModel;
Got it yet? Here's the answer:
one of them has a
;
which shouldn't be there
I just add the line twice, and deleted... problem solved!
@model MyApp.Core.ViewModels.LayoutViewModel
@model MyApp.Core.ViewModels.Layout_OrOther_Model
Try to compile, you get an error (only one model blah, blah..) Delete one of them.
@model MyApp.Core.ViewModels.LayoutViewModel
Compile.
That works for me!
