Missing reference to Castle.ActiveRecord when compiling in Release

Question

In debug, everything builds normally. When I try to compile in release mode, I get:

"The type or namespace name 'Castle' could not be found (are you missing a using directive or an assembly reference?)"

I obviously have the reference, or the project would not compile in debug either. So, what am I doing wrong?

Answer 1

I had a similar problem recently (with some other assemblies). Restarting VS helped.

Answer 2

I had to restart my computer in order to fix this.
