ASP.NET Podcast Show #149 - MonoDroid Development on the Apple Macintosh OSX

admin — Thu, 27 Jan 2011 11:59:00 GMT

Given that I have a cast on my arm, I installed the MonoDroid Development Framework for Apple Macs today. I walked through it and found that things are pretty much the same as with the MonoDroid plugin for Visual Studio 2010. This post shows the video displaying this. This video is based on MonoDroid Preview 11.1.

----- Code Sample Notes -----

Four (4) assembly references are needed for a cache project:
CacheBaseLibrary.dll
CASBase.dll
ClientLibrary.dll
FabricCommon.dll
Import System.Data.Caching for code using Velocity
You must start with a CacheFactory. No parameters in the construct means to read from a configuration file.
From there, cache is accessed via a CacheName. You can use Cache.DefaultCache for the default (returns null) For CTP2, you cannot easily seek out if a region is created.
Cache.DefaultRegion is null as well.
There is quite a bit of log messages that are exposed by default in Velocity. Especially for a Cache Miss.
