My group is developing a service-based (.NET WCF) application and we're trying to decide how to handle exceptions in our internal services. Should we throw exceptions? Return exceptions serialized as XML? Just return an error code? Keep in mind that the user will never see these exceptions, it's only for other parts of the applicatio...
Linux has libnotify and OS X has growl. Is there some kind of Notification API for Windows too? It should be accessible via .Net languages. Clarification: Yes I'm looking for an way to send notification to the user, but it won't harm if one can subscribe to certain events with programs too. The linux libnotify uses a system wide D-Bu...

Let's say I'm building a data access layer for an application. Typically I have a class definition for a each kind of object that is stored in the database.

I find it hard to come up with a good 'default architecture' from ...
Are all of these equal? Under what circumstances should I choose each over the others? var.ToString() CStr(var) CType(var, String) DirectCast(var, String) EDIT: Suggestion from NotMyself TryCast(var, String) ...
Has anyone had a chance to dig into how F# Units of Measure work? Is it just type-based chicanery, or are there CLR types hiding underneath that could (potentially) be used from other .net languages? Will it work for any numerical unit, or is it limited to floating point values (which is what all the examples use)? ...
Here's a quick question I've been banging my head against today. I'm trying to convert a .Net dataset into an XML stream, transform it with an xsl file in memory, then output the result to a new XML file. Here's the current solution: string transformXML = @"pathToXslDocument"; XmlDocument originalXml = new XmlDocumen...
I'm trying to use the OpenNETCF RAPI class to interact with a windows mobile device using the RAPI.Invoke() method.

The .NET System.Security.Cryptography namespace has a rather bewildering collection of algorithms that I could use for encryption of credit card details. Which is the best? It clearly needs to be secure for a relatively short string. EDIT: I'm in the UK, where I understand we're OK storing encrypted credit card details so long as the ...

What's the "best" (taking both speed and readability into account) way to determine if a list is empty? Even if the list is of type IEnumerable<T> and doesn't have a Count property. Right now I'm tossing up between this: if (myList.Count() == 0) { ... } and this: if (!myList.Any()) { ... } My guess is that the second option is fas...
