OrderAlloc Adapter - cannot be used with Type arguments

Hello! Hoping this will be quick and lay the groundwork for others. Trying to use OrderAlloc adapter. Old code doesn’t work anymore:

Erp.Proxy.BO.OrderAllocImpl oaAdapter = WCFServiceSupport.CreateImpl<Erp.Proxy.BO.OrderAllocImpl>(((Ice.Core.Session)oTrans.Session), Epicor.ServiceModel.Channels.ImplBase<Erp.Contracts.OrderAllocSvcContract>.UriPath);

Results in “Cannot be used with type arguments” compile error.

I tried

Erp.Proxy.BO.OrderAllocImpl OAa = new Erp.Proxy.BO.OrderAllocImpl(oTrans);

But that’s not getting me anywhere either. Thank you for any input.

Erp.Adapters.OrderAllocAdapter OAa = new Erp.Adapters.OrderAllocAdapter(oTrans);

forehead-slap it’s been a long day.
