Ingo Rammer's "Advanced .NET Remoting" is pretty much the authority on
Remoting. In my opinion, you won't find a better reference.

However, if you're just starting a project, you may want to consider using
WCF instead. WCF is designed to replace Remoting's proprietary technology
with something that can interoperate with non-.NET applications. In virtually
all cases, WCF will be faster than Remoting and yet it offers more flexible
options for security and communications transports.

Unfortunately, I haven't found the WCF equivalent to Rammer's Remoting book.
