In my case, I found that installing mono-complete did not allow my application (CloudBerry Explorer) to function, as it was looking for configuration files that running via Mono did not properly find.
I'm running on a x64 system, which .NET 2.0 won't install on (see http://appdb.winehq.org/objectManager.php?sClass=version&iId=3754), so I found that I had to remove my wine directory and do:
export WINEARCH="win32"
winetricks dotnet20
(Alternatively, you could set a different WINEPREFIX for the application with a win32 architecture, but I had no need for that kind of separation of environments, and nuking my previous setup was perfectly acceptable.)
At this point I wanted to run winetricks mono28 but winetricks has not yet been updated to account for Novell removing the file from their mirror (see http://code.google.com/p/winetricks/issues/detail?id=221). I used the proposed solution in the ticket:
wget http://download.mono-project.com/archive/2.8/windows-installer/9/mono-2.8-gtksharp-2.12.10-win32-9.exe
wine mono-2.8-gtksharp-2.12.10-win32-9.exe
(This took about 30 minutes to download as the mono-project.com servers do not have the same kind of juice that Novell had, sadly...) It allowed the application I wanted to use to run (it has some issues but I think that's more about Wine support than it is the .NET support).
