Answer 1

TryGetValue() is not a member of System.Web.Mvc.IValueProvider. I suspect he has a custom extension which looks something like:

public static bool TryGetValue(this IValueProvider valueProvider, string key, out ValueProviderResult result) {
    try {
        result = valueProvider.GetValue(key);
        return true;
    }
    catch {
        result = null;
        return false;
    }
}

Update

TryGetValue() is not an extension method, but rather it is a method on the type IDictionary. The type of bindingContext.ValueProvider has changed since MVC1 as @mootinator indicated. It's possible you can just ignore the call to TryGetValue() and instead call GetValue() and check the result for null. I'm not sure if it will throw an exception as I haven't tested it, so try that first.
