Question

I am running a linq query against CRM 2011 and I keep getting this error:

Invalid ‘where’ condition. An entity member is invoking an invalid property or method.

My code looks like this:

        try
        {

            string rsmName = "Bob Harrison";
            var linqQuery = (from r in gServiceContext.CreateQuery("opportunity")
                             join c in gServiceContext.CreateQuery("account") on ((EntityReference) r["accountid"]).Id equals c["accountid"] into opp
                             from o in opp.DefaultIfEmpty()
                             where ((EntityReference)r["ownerid"]).Name.Equals(rsmName)
                             select new
                                        {
                                            AccountId = !r.Contains("accountid") ? string.Empty : r["accountid"],
                                            Account = !o.Contains("name") ? string.Empty : o["name"]
                                        });

            ddlCustomer.DataSource = linqQuery;
            ddlCustomer.DataValueField = "AccountId";
            ddlCustomer.DataTextField = "Account";
            ddlCustomer.DataBind();
        }
        catch (Exception ex)
        {
        }

Any idea how to fix this?

Thanks!

It looks CRM Linq provider has a limited capabilities and the query is too complex. Try to use FetchXml.
