I'm having an issue with the Where clause in a search, in my original version EF4 I could add a Where clause with 2 parameters, the where clause (string predicate) and a ObjectParameter list such as

var query = context.entities.Where(WhereClause.ToString(), Params.ToArray());

since my upgrade to EF5 I don't seem to have that option am I missing something?

This was originally used to build dynamic where clause such as "it.entity_id = @entity_id" then holding the variable value in the ObjectParameter.

I'm hoping I don't have to rewrite all the searches that have been built out this way, so any assistance would be greatly appreciated.

Cheers
