Is it possible to create a library that can be consumed from .Net 2.0 and also allows .Net 3.0+ consumers to benefit from DataContracts if they wish? I don't see any technical obstacle for this other than the library that contains the different DataContract related attributes is a .Net 3.0 library. Can these attributes be implemented ma...
I have a situation in which I am attempting to keep my model and implementation as loosely coupled as possible, however I am faced with a situation where the coupling could potentially get a lot closer than I want. I have a selection of 'Model' classes, all implementing interfaces. Additionally I have 'Data Access' classes, which provid...

Ended up with this awful data structure: List<KeyValuePair<string, KeyValuePair<string, string>>> It's not likely to get huge (<1K I estimate) and I am gonna iterate this list over and over. Anyone can think of some better alternative with built-in types? ...
I'm trying to troubleshoot an application built against version 9.1 of a vendor's libraries on a machine that has their 9.3 version installed. The vendor provided a publisher policy file that redirects all versions from 9.0 onwards to their 9.3 dlls, and it is installed in the GAC. With a newer version of our application, built against ...
I asked this question yesterday and got a great response/code example. The only problem is that I forgot to mention that I am forced to work with the .Net Framework 2.0 and can't use the List.Select ( I assume the linq namespace). Does anyone have a good work around for List.Select seen below: class Program { struct ProcessStartTi...
So, I've been playing with asp:PasswordRecovery and discovered I really don't like it, for several reasons: 1) Alice's password can be reset even without having access to Alice's email. A security question for password resets mitigates this, but does not really satisfy me. 2) Alice's new password is sent back to her in cleartext. I w...

Instead, I'd like to have it only open when the user explicitly clicks on the drop down button. When the user clicks on the rest of the combo box, I'd like to just assign it the...

I notice that when I try to create DataClass to be passed in the web service that each DataContract attribute now has...

I have a set of .NET components that were developed long ago (1.1). I would like to continue to provide them for 1.1 for any clients that need that version, but also offer versions - in some cases the same code, in some cases with enhancements - for .NET 2 and for .NET 3(.5). In each later case, I might want to take advantages of newer f...
Here's my problem. I'm currently trying to develop a .Net Compact Framework 2.0 application (in C#) to a Windows CE 5.0 device. Firstly: How do I debug/emulate the application in Visual Studio 2008 ?

Perhaps my eyes are fooling me, but how is it that in .NET 2.0, XmlReader implements Dispose but does not have a Dispose() method? I see it has Dispose(bool), but not a parameterless overload. ...
