Silverlight Managed Wrapper for Virtual Earth

I have been doing a lot of work with this wrapper (called VIEWS, and available here: http://codeplex.com/views) - it really makes life a lot easier for working with VE in Silverlight, and will no doubt point the way towards how the final Silverlight VE control will work. I recommend checking it out, and watching this intro video from Jared Bienz is a good start Virtual Earth Mapping in Silverlight with VIEWS   Cheers Ian Technorati Tags: Silverlight,Virtual Earth

Silverlight Wcf: The remote server returned an unexpected response: (404) Not Found.

EDIT:  See http://www.bbits.co.uk/blog/archive/2008/09/12/debugging-wcf-services-in-silverlight-2.aspx for further help on this.  Keep getting this error on a Silverlight 2 B2 project that is referencing a WCF service in a Web Site (not web project). There doesn't seem to be any reason for it, and it happens intermittently, however the workaround I have for it currently is to simple open up the cs class for the service and make any edit (e.g. just add a comment line) and then build.  This seems to fix it for a while. Hope there is a better solution long term, or a fix for this somewhere... Ian   Technorati Tags: Wcf,Silverlight

The Amazing Album Cover Atlas

http://theamazingalbumcoveratlas.org/ The excellent Word Magazine recently created an album cover atlas which shows locations of famous album covers.  Cool idea, but I didn't like the basic google maps interface.  So as an exercise and to also help spike out some work we are doing on www.lovecleanstreets.org I created a quick Virtual Earth and Silverlight version that make use of the VIEWS VE managed wrapper for Silverlight. Luckily the original developer, Ian Reeves used a REST service to get the data, so I was able to work with the same live data for my project.  There was no...

Being enticed by Live Mesh

Live Mesh is in early days yet, but having had it installed for a while, I am starting to see the possibilities.  The mobile web client is now available (though the full mobile client is still "coming soon") at http://m.mesh.com and using this to upload an image and then see it appear almost instantly on your other devices is compelling. The real power of Mesh will come with the api - then we can start to really create apps that live on and offline easily.  I am eagerly anticipating when that will be available (my guess: the PDC).  In...

Linq Performance with Generic Lists

** UPDATE * - this is messed up!  read the comments for more details... A question came up today on MsWebDev as follows: I have two lists of integers, each with approximately 300,000 integers in them. I need to work out which integers are in List A but not in List B. Their first thought was to "literate through List A and ask if List B contains the current integer. If it doesn’t then I add it to a third list and return that at the end", but this was giving poor performance (10 minutes!) The use of a Hashtable was suggested, and...
