• Automatically inserting new fields in a web.config file

  - by MarceloRamires

  I have an ASP.NET project which has already some custom fields in it's web.config file. I've added in it three more fields and used them in my changes, and it's working great. But where it needs to be used, there aren't these thre fields in the web.config (this was expected, I've just added by hand for tests and developing). How do I check the existance of fields in web.config, and in case of not finding it, how do I add it permanently to the web.config ? Thank you

• Is there a downside to adding an anonymous empty delegate on event declaration?

  - by serg10

  I have seen a few mentions of this idiom (including on SO): // Deliberately empty subscriber public event EventHandler AskQuestion = delegate {}; The upside is clear - it avoids the need to check for null before raising the event. However, I am keen to understand if there are any downsides. For example, is it something that is in widespread use and is transparent enough that it won't cause a maintenance headache? Is there any appreciable performance hit of the empty event subscriber call?
