Richard Blewett writes about a custom channel sink to solve the problem where you get strange remoting error messages from a SerializationException about formatter version mismatches:

An unhandled exception of type 'System.Runtime.Serialization. SerializationException' occurred in mscorlib.dll

Additional information: BinaryFormatter Version incompatibility. Expected Version 1.0. Received Version 1008738336.1684104552.

I have to admit to being pretty mystified when I first came across this a few months ago having managed to steer clear of .NET remoting for the most part. This bit of code looks like a real boon for those moments when you run into this issue, which happen periodically as you maintain and update your remoting code.
