1. Difference between Proxy and Channel Factory in WCF
S.No Proxy Channel Factory
1 What is the prerequisite for

When we share a common service
contract dll between the client and
the server, we will be using the
ChannelFactory class.

If we know that our entities will
change much and the client
code is more, then we need to
go for Proxy.

gets and sets
2. Constructors cannot be
exposed
3. Methods other than the
service contract cannot
be exposed
