Using locks to implement a thread-safe collection is rather like using a sledgehammer - unsubtle, easy to understand, and tends to make any other tool redundant. Unlike the previous two collections I looked at, ConcurrentStack and ConcurrentQueue, ConcurrentDictionary uses locks quite heavily. However, it is careful to wield locks only where necessary to ensure that concurrency is maximised. This will, by necessity, be a higher-level look than my other posts in this series, as there is quite a lot of code and logic in ConcurrentDictionary. Therefore, I do recommend that you have ConcurrentDictionary open in a decompiler to have a look

at all the details that I skip over. The problem with locks There's several things to bear in mind when using locks, as encapsulated by the lock keyword in C# and the System.Threading.Monitor class in .NET (if you're unsure as to what lock does in C#, I briefly covered it in my first post in the series): Locks block threads
The most obvious problem is that threads waiting on a lock can't do any work at all. No preparatory work, no 'optimistic' work like in ConcurrentQueue and ConcurrentStack, nothing. It sits there, waiting to be unblocked. This is bad if you're trying to...(Read whole news on source site)

Introduction Almost a year and a half ago (as you can probably tell from my bio in the screenshot), I sat down and starting reviewing the Silverlight 5: Building Rich Enterprise Dashboards book. Fast forward to last month, this book became available for sale. It was a pleasure being part of the technical review for this book and I learned a lot of things throughout the review. I wanted to take a brief moment and tell you what the book has to offer.
But first, the Giveaway I’ve got 3

copies of the eBook to give away – sorry no physical books. I know that a majority of people would rather have the electronic version where they can take it with them everywhere. All you have to do is leave a comment below where I can track you down. I’d also appreciate you leaving your twitter handle where I can send you a tweet. I will randomly select 3 winners on 2/29, so act fast.   Book Overview Microsoft Silverlight is a powerful development platform for creating rich media applications and line of business applications for...(Read whole news on source site)

Join us on Thursday, February 23 at 9:00 AM PST | 12:00 PM EST | 5:00 PM GMT for the next PostSharp Live Webinar when our guest will be Ward Bell. Ward is V. P. of Technology at IdeaBlade and, with over 25 years of application development experience, he champions the company's customer-focused product direction. Due to the popular demand of last week's live webinar, we've asked Ward to join us again to show how IdeaBlade's DevForce product uses PostSharp to infuse “Code First” entity model classes - entities like Customer and Order –

with rich behaviors that go way beyond property change notification. During the webinar you will learn: How IdeaBlade uses PostSharp to achieve important product goals Which alternatives to PostSharp the company considered, and rejected What initially worried IdeaBlade about using AOP and PostSharp Where IdeaBlade is planning to go next with PostSharp If you've ever wondered what difference AOP and PostSharp can make in real products, and want to gain insight into how it can help with your own project,...(Read whole news on source site)

source: blog.chevonchristie.com One of my biggest frustrations with Windows Phone has been getting an image to zoom somewhat smoothly in an app, as well as behave the way a user would expect it to. Attempts have been made to remedy this problem, most notably the MultiTouchBehavior, which is available on codeplex. However, none of the attempts proved, based on my judgement, satisfactory (until now of course). In my rampant search to find a "good" image zooming implementation, akin to what is experienced in the Windows Phone web browser and other native apps, I stumbled upon the

IndexOutRange blog, where another dev has taken what I consider a successful stab at the problem. How I missed it before? I don't know. But once I saw it, I used it as a jumping off point and made zooming even easier to work with. ...Read more ...(Read whole news on source site)

The goal of this blog entry is to describe the Promise class in the WinJS library. You can use promises whenever you need to perform an asynchronous operation such as retrieving data from a remote website or a file from the file system. Promises are used extensively in the WinJS library. Asynchronous Programming Some code [...]

  Introduction:

              Recently while working on an application I ran into an client side validation issue. The issue was that ASP.NET MVC 3 application ignoring the cancel class(which is used to disable the validation of a particular submit button), when you use unobtrusive ajax(for example, Ajax.BeginForm helper). This issue is also present in ASP.NET MVC 4 Beta at two places. Ben Reich raised this issue at http://aspnet.codeplex.com/workitem/7964. In this article, I will show you the issue and a quick solution.   Description:                To understand this issue just add s Ajax.BeginForm helper with a submit button in your ASP.NET MVC 3(or

ASP.NET MVC 4) application. Set the submit button class to 'cancel'. Run this application. You will find that the application is ignoring 'cancel' class(which is used to disable validation). Similarly, add a submit button with 'cancel' class inside new Login popup of ASP.NET MVC 4 Beta application, you will get the same issue. To resolve this issue just open AjaxLogin.js file(for only ASP.NET MVC 4 Beta) and replace this,   .submit(formSubmitHandler)            with,   .submit(formSubmitHandler) .end() ...(Read whole news on source site)
