winforms

I couldn't find any close answers to this, so I'm consulting the experience of SO users:

Scenario:

I have two small C# winforms applications where one behaves as a server or host, the other as a client. They share data via SQL Server, in terms of configuration settings.

I am currently launching the client application (which only needs to run periodically) from the server application via Process.Start() and terminating it via Process.CloseMainWindow() (after finding it in the process list).

While it seems clean enough, I wondered if there's a better way.

Question:

Which way would be best to instruct the client application to shut down:

Continue using Process.CloseMainWindow()?
Implement WCF between the applications? (I would need help on how to do this.)
Set a variable in SQL that the client application checks for?
Some other way?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
