On 2 Feb at 1000 PST, I will be doing a Webinar on the SilverlightShow site on using WCF RIA Services to query and update data. If you have been following my series on WCF RIA Services, this will parallel the content there closely, so acts as a nice visual complement to the written version. This session will attempt to cover everything in the first couple articles in a single hour(ish) session. I will be doing subsequent Webinars there about every month to cover the other aspects shown in the series and will probably show more than is covered in the written series.
So check it out.
