Frequently Asked Questions (FAQ)

Get answers to frequently asked questions about the Base Class Library (BCL).

We love to hear about any ideas, issues, or requests you have. You could be wanting to know why something was designed a particular way, how best to solve a problem, or why your code isn't working the way you expect. In addition, feel free to send the BCL team any suggestions for future releases of the Framework, such as additional classes to include (it always helps to outline a scenario you need to support), or new APIs for existing classes.

To submit your question, simply send an email to The BCL Team (bclpub@microsoft.com)
