ScottGu's Blog — Sat, 02 Jan 2010 21:05:17 GMT

[ In addition to blogging, I’m also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu ] Hope you all had a great holiday – welcome to 2010! Last month I did a blog post about some of the presentations I did in Europe and posted the slides+demo files from them. High-quality videos of the talks I did in Sweden were posted two weeks ago on the Channel9 site, so you can also now watch videos of the talks online as well. The videos use a nice format where you can watch me talking as well as the screen at the same time. The code is readable when running in full-screen mode. Below are links to the different talks along with the slides+sample files: ASP.NET 4 and VS 2010 Web Development This...(read more)

ScottGu's Blog — Thu, 17 Dec 2009 05:56:57 GMT

[ In addition to blogging, I’m also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu ] Last month I gave a Silverlight 4 keynote at the PDC conference. You can watch my keynote online here (my part of the keynote starts at the 53:30 mark in the video). I showed off a number of fun demos during the keynote that highlighted some of new features coming in Silverlight 4. Today we posted the samples online (with code) so that you can download and run them locally on your own machines. You can download the keynote demos here (source code + VS project file included with each sample).

Visual Studio Project Sample Loading Error: Assembly could not be loaded and will be ignored. Could not load file or assembly or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)

Brad Abrams — Sat, 12 Dec 2009 04:21:34 GMT

Some folks have mentioned to me that they are having trouble getting some of my samples to work. And in fact, just the other day, I ran into a problem getting my own samples to work. It turns out to be a problem with the way windows treats the sample that you down load. Specifically, because you downloaded the sample from the internet, windows treats the sample as “untrusted” content. When you unzip untrusted content you get a directory full of untrusted content. Visual Studio is not so good and running untrusted content. Unfortunately, you get some really bad error messages like the one above. Here is the error message from VB Warning 1 Assembly 'C:\Users...(read more)

ViewModel Pattern for Silverlight - Options for Hooking a View to its Model

Nikhil Kothari's Weblog — Fri, 11 Dec 2009 17:42:13 GMT

In the ViewModel, aka the MVVM pattern, a view such as a UserControl is bound to its associated view model. The view model manages state exposed as observable properties, operations exposed as methods and raises notifications via events. An interesting question is how a View should specify its view model, and how a view model instance should be created. Like everything else in the ViewModel pattern, this topic is no different. There are different strategies, with pros and cons, and different people have different opinions. In this post, I'll describe a couple of options, and hope to collect some feedback as well as ideas on alternatives. Part of my goal here is to improve what is supported in Silverlight.FX out-of-the-box. The other goal...(read more)

Field Level Access with RIA Services

Brad Abrams — Tue, 08 Dec 2009 18:56:38 GMT

There are lots of reason you may need to customize the access to given fields within an entity. For example, HIPPA compliance requires that some data not be exposed to only employees with a need to know. It is often not sufficient to just NOT show the data in the Silverlight client, you need to not even send it over the wire. This example works with Silverlight 4\RIA Services Beta and Visual Studio 2010 Beta2 I built a very simple RIA Services + Silverlight 4 example to show how this could be done. First, let’s run the app, then we can look at how we built it. The first thing to notice is when we run it, no users are logged in, so we get no access to the data at all. First, let’s log in as a Rocky, who...(read more)

My Presentations in Europe (December 2009)

ScottGu's Blog — Mon, 07 Dec 2009 02:04:10 GMT

This past week I’ve been traveling around Europe giving a bunch of presentations (approximately 5 hours in each country) – Norway on Tuesday, Sweden on Wednesday, Denmark on Thursday, and Belgium on Friday. I’ll then be presenting at the BizSpark Camp in France this coming Tuesday. Things went well with the talks, and I had fun meeting lots of new people (more than 3,000 attended the talks!). Below is a picture of my talk in Belgium – where everyone showed up in a red shirt :-) Download Talks My talks were filmed in a few locations – and I’ll update this post with pointers to the videos once they are online to watch.

Silverlight and RIA Services: Implementing Search

Brad Abrams — Wed, 25 Nov 2009 19:11:51 GMT

Some of you likely noticed that my PDC09 demo included a stubbed out Search function that I didn’t really get to walkthrough during the talk. I thought I’d do a blog post showing how it is done. To get started you need: Visual Studio 2010 Beta 2 Silverlight 4 Beta (which includes RIA Services) You can download the completed solution as well. and be sure to check out the full talk . First let’s write a new method on the DomainService to return the search results. In this case I want to return any Plates who’s name matches (grouped by Restaurant) and any Restaurant who’s name matches. public IQueryable < Restaurant > SearchRestaurants( string term) { //Find all plates that match, grouped...(read more)

RIA Services: Jumpstarting RIA Development

Nikhil Kothari's Weblog — Thu, 19 Nov 2009 09:03:31 GMT

In my post on RIA Services: From Vision to Architecture , a while back (right after MIX09), I mentioned that I like to think of RIA Services as RAD for RIA. At that point we had a very early preview of framework bits with little tools support. A large part of jumpstarting your development actually centers around good tooling. VS2010 brings tooling for RIA Services (now: WCF RIA Services). Scott Hanselman demonstrated some key features used in building a Contacts application (as shown on the right) during the keynote at PDC09 . The latest version of RIA Services is now available for download. It works on .NET 4 and VS2010 as well. You can also check out a video tutorial on using RIA Services and Visual Studio 2010. In this post, I want to highlight...(read more)

Welcome to WCF RIA Services Beta!

Brad Abrams — Wed, 18 Nov 2009 16:57:43 GMT

Today at PDC09 , Scott Guthrie Announced the beta of WCF RIA Services . As you may know RIA Services is a set of end-to-end experiences that makes it as easy to build Silverlight based n-tier applications as it is to build traditional 2 tier apps. I am very excited about this release as it represents a lot of great feedback we have heard from many of you. A few goodies in this release based on your feedback You told us you wanted to get up and running with the UI quicker, so we enabled the “DataSources” window that allows you to drag and drop “tables” exposed by your Domain Service onto the form and get meaningful UI to start with. No more guessing about the Xaml syntax for databinding, or incantation...(read more)
