turn on assert in asp.net

My ASP.NET asserts aren't firing. Build configuration is debug. what gives?

EDIT: They are firing and silently hanging my website (exiting the thread).

I believe you probably lack this:

   <assert assertuienabled="true" />

in your web.config.

is there a way to make them more intrusive (not just log to output, like actually get in my face)

Are you using a separate server for your development ? Because an Assert will trigger a modal message box on your server which will hang your website until the message box is closed.

VS is running on the same host as the server. But I see no box.
