I am performing a code review (VS2008/.NET 3.5). The development team has created several data access components in a DAC assembly. I encountered a business proces assembly where every DAC is wrapped with a business component with no additional value or code. Is this a right premature architectual step ?

Hi, I have a standard Visual Studio (2008) application setup project, which generates an msi containing a few files. I noticed however that: 1) When the msi installs and some of the files already exist, it simply silently ignores these files. This is the behaviour that I don't want, because of obvious reasons. 2) When I uninstall the ms...
I've written some code that is supposed to write a file to the temp directory, then copy it to a permanent location, but find that doing so creates a permission-related error on the copy command. The code looks like this: string tempPath = Path.GetTempFileName(); Stream theStream = new FileStream(tempPath, FileMode.Create); // Do s...

Which one is a better practice in programming? I am not talking about complete exclusivity. It's more for things like: list<T>.Find, where you get default(T) or your value, instead of ValueNotFound exception (example). or list<T>.IndexOf, where you get -1 or the correct index. ...

My program starts a process and I need to make sure it is killed before I can run the program again. To do this, I'd like to store the start time of the Process in something like a mutex that I could later retrieve and check to see if any process has a matching name and start time. How could I do this? I don't really want to stick anyth...
