Exposing DCOM service through CF service.

Hello,

My company has plans to make the existing DCOM service available to new
..NET clients and java clients using WCF. This DCOM server has almost
40K+ lines of code and has all the interactions with different driver
components.

We want to expose this DCOM server to new clients(.NET and java) using WCF.
Company wanted to keep their existing investments rather than rewritting the
DCOM server.

I searched MSDN and found some links about COM+ and WCF integeration. Looks
like this does'nt work for DCOM service.

I have the following question, i hope somebody from microsoft or anybody
else can give me the good advice how to move forward.

1. Looks like nothing comes from out of the box for supporting COM with WCF.
Can i write an .NET assembly inside the WCF which talks to the DCOM server
using a .NET CLI/.NET CSharp assembly which does the interops in talking to
the DCOM.

So when clients call a contracted interface exposed using WCF, i can use
this interop assembly to talk to the DCOM server and get the data back.

We also have ATL connection point call backs in DCOM, can i have .NET sink
object created in the WCF service, which receives the callbacks from DCOM and
pass backs these callbacks to the .NET clients through WCF.

Any help from anybody will be greatly appreciated.
