How should you implement Serialization? (interface/convention wise)

I implement an xml serialization based on Marc's answer. Should this be part of the class itself, ie Apple.Serialize/Deserialize? Although Deserialize would be static in that case, as you might not have an instance to call it on. Or should I have another class for Serialize/Deserialize? If so, these seem to be generic enough? What sho...

How to programmatically configure IIS7? (without using the Metabase)

Consider a .NET application that performs lots of configuration changes in IIS such as changing Virtual Directories or enabling compression. With IIS6 everything could be accomplished using the metabase through DirectoryServices.

I would like to have the checkboxes A...

Running an Open Source project in .NET C#

We have developed an application in C# .NET WPF Office which we are about to Open Source. I'd be interested in the objective factors that we can address to increase the likelihood of success. It's a domain application on top of the MS stack, so we would be particularly interested in any experience of groups doing this (as opposed to writ...

Ignore field order in DataContractSerializer

When deserializing, DataContractSerializer requires not only that an element name matches, but also that it is in a certain order with respect to the other elements. My application is such that every field can be uniquely identified by its name. I would therefore like it to be possible for the XML file to contain the elements in any ord...

Simple data file versioning with DataContractSerializer

Having read Data Contract Versioning we concluded that it's not really the whole story. For example, what happens if you used to have ValueA, and in the new version it's now called ValueB and is of a different type, and you need to convert ValueA to ValueB? There are some callbacks I could use to help with this, but it doesn't look like...

Is Linq to SQL still a viable choice for developing applications?

I'm reading up on .NET things again after a brief (and occasionally ongoing) stint with Ruby on Rails. I'm wondering if LINQ is still a choice when choosing an ORM for new applications, or if I should learn something like NHibernate instead which seems to still be going strong. I know that Linq has basically been subsumed by the Entity...
