Entity Framework - Cannot convert lambda expression to type 'string' because it is not a delegate type

Question

I am using Entity Framework in my C# based code. I am running into an unexpected weirdness and am looking for suggestions.

Case 1, 2, 3, 4... Projects:
RivWorks

Answer 1

My issue involved the format:

.Columns(columns => {
    columns.Bound(p => p.Id).Filterable(false);
    columns.Bound(p => p.Name).Width(250);
    ...

Every p.Whatever had this error on it.

This was a project using MVC, and I found my issue was having "public static int" or "public static string" on these variables (Id, Name, etc.) in my model. When I removed "static" on all my model variables, I no longer got the error. Was driving me nuts for about a day...
