c# wcf .net-3.5 channel servicehost
I’m running across this very strange behavior when using the IChannel interface. Basically what the code does is it spawns a process that loads CLR 4 (our application natively loads CLR 2 / .NET 3.5) and hosts a “ServiceContract” which will do some work and return a “DataContract” (serialize it, return it, deserialize it). Here is the code that spawns the IChannel:static Binding CreateBinding(){NetNamedPipeBinding binding = new NetNamedPipeBinding(NetNamedPipeSecurityMode.None);binding.Security.

These icons may or may not exist on disk – for example, we wanted to make our own custom file browser and want to display the system-associated icon with the file.Is there a native C# way to get the icons for various file types (and if so, how) or must it be done through PInvoke with shell API?And as a follow up, if th

Examples involving duck typing are welcome as well, so do not shy away from mentioning these languages.Update: I figured out that Smalltalk has changeClassTo and become. CLOS can do change-class.

The expando allows creating and removing members at runtime, much like a hash (similar to JavaScript).Why the ExpandoObject goodness was implemented in a separate class rather than just being, let’s say, implemented as a feature of anonymous types?Maybe that wouldn’t be a good move because the lacking of t
