Design Smell?

Dude, this :
OperationContext.Current
is a design smell....
How do you test / mock it ?

You guys need to look at inversion of control :

http://www.martinfowler.com/articles/injection.html

class ServiceImpl : IServiceSide
{
public property OperationContext ctx{
set{ ctx = value; }
}

public void Rotate(string s)
{

IClientSide client = ctx.GetCallbackChannel<IClientSide>();

etc....

simple and testable.

you can use annotations instead of signature if you prefer :

[RequiresContext]
public void thisIsWhereWeGetTheContext(OperationContext ctx)

Zohar, I believe that you assume that the context and the CLR object instance are the same across calls - this may not be true in all cases. I guess this calls for a blog entry about instancing :-)
