I am running two 4.7.0 sites where i've just "half upgraded" (by replacing the binaries) the site to 4.7.1 to test razor features.A few things are probably broken as the aspx/ascx/asmx/css/js etc files should also be updated.I don't recommend this for a production site,This build is current as of 2011-07-22 and I will periodically update ithttp://dl.dropbox.com/u/2923715/LatestRazorMacroEngine.zip
FYI, I use "ContainsAny" in Razor C# and I think it is really nice to have this feature working.
Thus, thank you Gareth Evans for your help fixing/patching the "ContainsAny", I will test your patch. Much appreciated. :)
