I read a bit about the overall idea of this technology but it reminds me of a few decades ago when we were told "in the future you won't write code, you'll connect boxes in some graphical tool". Is it a technology which has become central in .NET development (like WCF and WPF have) or has it failed to catch on? ...

Hi all, We are trying to use the .NET LicenseManger/Provider for our own custom component. However, it seems that this can't really be used if the licensed control will be wrapped in a 3rd party user control itself, since the saved license is always embedded in the control assembly in that case, which would force the consumer of that co...
If I have a method or a property that returns an IEnumerable<SomeType> that leads to no data, is it more efficient to return an empty array new SomeType[0] or is it better to return an empty list new List<SomeType>() or is there an even better solution (IMO building an own type with generics could be such a solution but it seems to me a ...

I've got a server app that offers data to a number of clients over network. You can imagine the data as a huge list of strings. The data on the server may change and need to be synchronized on all clients.

I'm trying to print a WPF canvas over multiple pages. I'm perfectly happy with scaling it to fit on the page width, then clipping and translating the canvas for each page; all pretty simple maths. What I don't understand is how I get the dimensions of the printable area, and how to tell the printer where to print to. Whatever I try it ...
