Is there a way to use `dynamic` in lambda expression tree?

Question

First, spec. We use MVC5, .NET 4.5.1, and Entity framework 6.1.

In our MVC5 business application we have a lot of repetitive CRUD code. My job is to \"automate\" mos

Take a look at this answer. It uses reflection to get the ID Property. I think it solves your problem:

public static object GetPropValue(object src, string propName)
{
    return src.GetType().GetProperty(propName).GetValue(src, null);
}

Then you replace your lambda expression by

return entity => GetPropValue(entity, "ID");

I've not tested, since I have no code fully working to test it. If it works please let us know.
