System.Timers.Timer still broken
· 2010-02-23 20:17 by Thijs Kroesbergen for Brokenwire.NET

About one year ago I wrote about System.Timer.Timer and it’s exception silencing capabilities. Now the .NET framework version 4 is almost done I thought it would be nice to do the same test again on the brand new framework. And guess what? It’s still broken!

Just to be clear what’s happening here: when an exception is thrown in the .Elapsed event of a System.Timers.Timer object then the exception gets silenced by an empty catch block within the framework code surrounding this event. You can see the sample code for reproducing this in my previous post.

Now there are many discussions about the usage of empty catch blocks but the general opinion seems to be that empty catch blocks are usually a bad idea. So why is this not fixed yet?

There is even a Microsoft Connect bug for this issue, in which we are promised that this will be fixed in “a next version of the framework”. That bug was opened in 2007…

So, if you want .Net framework 4 to suck a little bit less: go HERE and vote for this bug. And remember: You ARE the framework ;)
