           Summary: IEnumerable does not support '.where' LINQ

I'm attempting to use MVC 2's editor templates, which commonly use the
following line:

<% foreach (var prop in ViewData.ModelMetadata.Properties.Where(pm =>
pm.ShowForEdit && !ViewData.TemplateInfo.Visited(pm))) { %>

But on Mono 2.10.2 (and 2.10.1, not sure about any other versions), I receive
the following error:

CS1061: Type
`System.Collections.Generic.IEnumerable<System.Web.Mvc.ModelMetadata>' does not
contain a definition for `Where' and no extension method `Where' of type
`System.Collections.Generic.IEnumerable<System.Web.Mvc.ModelMetadata>' could be
found (are you missing a using directive or an assembly reference?)

suggesting that perhaps that attribute is not properly supported in Mono?

Reproducible: Always

Steps to Reproduce:
1. Use the line above in a MVC 2 editor template.

Actual Results:  
Compilation error:
