Try:

var query = from a in db.Table1
            where a.Letter == "y" && !(from b in db.Table2
                                       where b.fk_Planid == "30"
                                       select o.CustomerID).Contains(a.Product_ProductServiceName)
            select new
            {
                ProductServiceName = Product_ProductServiceName,
                ProductClass = ProductClass
            };

I'm using vb.net sorry.  I tried to do the conversion but I have a question where did the o .customerid come from?  Also when I get beyond the select new statment I get several other errors.  Thank you so much for your help.

My fault--I forgot to change that piece. Try this VB version:

Dim query = From a In db.Table1 _
            Where a.Letter = "y" AndAlso Not (From b in db.Table2 _
                                              Where b.fk_Planid = "30" _
                                              Select b.ProductServiceName).Contains(a.Product_ProductServiceName) _
            Select New With _
            { _
                a.ProductServiceName = Product_ProductServiceName, _
                a.ProductClass = ProductClass _
            }
