I am creating a report of a user's activit...

I'm looking for a tool that can collect quality metrics for C#/.NET code. I'm aware of NDepend - are there any other tools that I should look into? Ideally, I'd like to find something that could be integrated with an automated build process - something that could export a text-based report (I'd like to be able to easily email and archive...
A lot of the code base methods my peers have written perform their own error handling, usually by catching, notifying, and logging. In these cases the methods return a boolean, indicating success or failure. Sometimes though, if a method fails, I want the calling code to know why, and returning a boolean is not enough.

Hi, I have some SerialPort code that constantly needs to read data from a serial interface (for example COM1). But this seems to be very CPU intensive and if the user moves the window or a lot of data is being displayed to the window (such as the bytes that are received over the serial line) then communication gets messed up. Consideri...
Hi, From past few months I am working on projects in latest dot net frameworks. I feel that in latest dot net versions "services" are encouraged over components. Is that correct? I have seen in silver light (I am a beginner in silver light) all the DB layer operations are exposed as services. I don't know right now component program...
