Does the .NET Compact Framework have built-in controls or API's that will do this? Or would I need to start looking for a third-party library? I'm a little co...

Hello: I've been thinking about nested try/catch statements and started to think about under which conditions, if any, the JIT can perform an optimization or simplification of the compiled IL. To illustrate, consider the following functionally-equivalent representations of an exception handler. // Nested try/catch try { try { ...

I find that writing web apps and WinForm apps generally come out a lot cleaner than when I write a console application. What do I mean by cleaner? Well the fact that the fact the UI (i.e. readline/writeline) is so intertwined with the logic code becomes horrible and the fact it is not event driven means that it is harder to get good ab...

I had a heated discussion with a colleague on the usage of stored procedures (SP) in a .NET application (on an SQL server 2005 database). [He has a Microsoft background and I Java - which may or may not be relevant]. I have to insert data captured in the UI. For this I would write a SP and use that in the .NET code?

What is the best way to unit test heavily database dependant .NET middleware? E.g. a process which reads data from multiple databases, manipulates it, and then combines and writes it to other databases? Should the databases be filled with static data which is somehow reset on each unit test run? Should the whole SQL Server access be som...
