I think the System.Transaction classes in Framework 2.0 are a great tool, well designed, aimed to simplify code when working with transactions. But, (big but), it's impossible to use those classes with multiple connections to the same database (same connection string) without promoting to distributed transactions. http://social.msdn.m...

Hi, we are curring analyzing whether to implement a solution for a software application by using either WPF or WinForms. Apart from that decision, I just wanted to ask whether someone of you has good resources in terms of UI design (i.e. layout) (papers, case studies, links, books...), preferably targeted to WPF. I do not necessarily ...
In VS2005 I have a few C# projects that depend on each other. If project A depends on B (e.g. references it), then I want B to build whenever I build A, assuming B has changed in some way since last built. That's the way it is with VC projects, but for some reason it doesn't seem to work with C# projects. If I clean B and then build A i...

I've been thinking that it would be useful to be able to do such a thing, for example, to check the parameters for null references and eventually throw an exception. This would save some typing and also would make it impossible to forget to add a check if a new parameter is added. ...
Env.: .NET / VS2008 Hi All, My app uses a 3rd party DLL assembly separately installed on some systems (clearly identified) but not all of them. Which means that on some systems, the DLL is not there hence must not be called. To solve this, I have 2 versions of the app (using 2 configurations) for the 2 use cases. In one of them, all ...
We have inherited a legacy system for reading to and from meter guns. This system was originally build on XP with .Net 1.1 (VS2003?). Having recompiled it on VS2008 with .net 3.5 we get an access violation when calling the dll (dll not touched). The original program (using basically the same code) is running fine on our production machin...

As far as I can see, the .NET api has support for this through the System.Security.Cryptography.Pkcs namespace. However it seems that the implementation can only work on byte arrays. So what do I do when I have a large encrypted file that does not f...
