  ??? System.EnterpriseServices allows you to access COM+ using managed (.NET code). The idea behind Serviced Components is that the COM+ runtime provides you will a set of services. You would need it if you want: -Distributed transactions -Scalability -Role based security

  Hi dfoderick I always thought these are the strengths of .NET because of .NET Remoting and WebServices. So what are the differences to COM+? bye graka

  As dfoderick posted in his above message you can get advantage of transactions and the rolebase security in COM+!! [Actually now in .Net you will get those from Enterprise services]

  But the .NET Framework supports security without COM+ (System.Security), codesecurity and role based security. And ADO.NET also supports transaction. So why COM+? bye graka

  Yes ADO.Net supports Transactions and also all COM+ features now available in .Net. It's going to be lengthy discussion. But below link can help you understand more. If you have time then please see below link, it might help you! http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndotnet/html/entserv.asp

  DISTRIBUTED transactions. 2pc = two phase commit. You need a transaction coordinator to monitor the transaction if it spans more than one machine. ado.net DOES NOT do this!!! I agree with role based security, you don't need com+, but if you are using it, it does support it. The other reason for com+ is scalability with clustering and component load balancing.
