In VB.NET type this on a new line:
DateAdd(
Shouldn't a dropdown picklist of enum values appear?
It used to! I miss it!
Of course, this is just one example where an enum pick list does not appear where it did before.
Can anyone defend this or is it a bug?
I tried this repro on my Visual Studio 2010 install and the enum drop down list popped up as expected. One possibility on your machine is that it's prefering the string overload of the method as opposed to the enum version. Can you confirm by telling us which tooltip is showing up when you type the ( ?
Check to make sure that all of your Intellisense options are turned on. I've installed 2010 a few times over the past few months, and the option is turned off by default seemingly at random. It drives me just a little bit crazy.
Tools->Options->Text Editor->All Languages->General
Ensure "Auto List Members" and "Parameter information" are checked.
If you only want this on for VB you could go into "Basic" instead of "All Languages".
