JayData–The cross-platform HTML5 data-management library for JavaScript

Last week, I wanted to call an oData service from my HTML5 metro app. First I was planning to use datajs until I discovered JayData which offers similar functionality to datajs and much more! What’s JayData? JayData is a standards-based, cross-platform Javascript library and a set of practices to access and manipulate data from various online and offline sources. JayData provides JavaScript Language Query (JSLQ) as a tool to query local (in-browser and mobile) and remote data sources with a simple, unified query syntax: JavaScript itself. Much like Microsoft .NET developers can utilize LINQ to perform operations on data from different databases. The aim of JayData library is to give a similar level of abstraction with the help of the $data.Expressions API and the JavaScript language itself. JayData is cross-platform (runs on HTML5 desktop and mobile browsers, can be hosted in PhoneGap environment on iPhone , iPad and A ndroid ) and cross-layer as it works on client-side a

Free ebook: Building Hybrid Applications in the Cloud on Windows Azure

The Microsoft Patterns and Practices team released a new version of the ‘Building Hybrid Application in the Cloud on Windows Azure’ ebook. “This book is the third volume in a series on Windows Azure. Volume 1, Moving Applications to the Cloud on Windows Azure, provides an introduction to Windows Azure, discusses the cost model and application life cycle management for cloud-based applications, and describes how to migrate an existing ASP.NET application to the cloud. Volume 2, Developing Applications for the Cloud on Windows Azure, discusses the design considerations and implementation details of applications that are designed from the beginning to run in the cloud. It also extends many of the areas covered in Volume 1 to provide information about more advanced techniques that you can apply in Windows Azure applications. This third volume in the series demonstrates how you can use the powerful infrastructure services that are part of Windows Azure to simplify development; i

Minification and bundling in ASP.NET: WebGrease

When installing the latest version of the Microsoft.AspNet.Web.Optimization package(before the Microsoft.Web.Optimization package)  I noticed a dependency on an assembly called WebGrease. So I started to look around what it is and found the following 2 blog posts: WebGrease: As seen in Visual Studio 2012 How to use WebGrease configuration files What is WebGrease? WebGrease is a suite of tools focused on assisting web developers with optimizing the "static" asset files (JavaScript, CSS) of a web application. The features the initial version includes are: Minification of JavaScript & CSS files Validation of JavaScript files Creation of image sprites from images reference in CSS files. Bundling of CSS & JavaScript files. Auto-version naming of files. The Web Optimization library uses some of the features WebGrease offers(currently only the Minification features for CSS and JavaScript). In order to use all of the features in WebGr

MSTest: use subfolders for your deployment items

Out-of-the-box when you have deployment enabled inside your .testsettings file, all files are put directly under the TestResults/Out folder . But what if you want to put your test files in a subfolder? This is something that isn’t possible through the testsettings editor , however it can be accomplished by changing the .testsettings file directly. Right click on the .testsettings file in your solution explorer.  Select Open With and select XML editor . Add a deployment item, specifying the relative path as the file name and an outputdirectory value of the directory name. <Deployment> <DeploymentItem filename="BuildCustomizations\TestFiles\" outputDirectory="TestFiles\" /> </Deployment> Now when you execute your tests, MSTest will copy the content of the ‘TestFiles’ folder to 'TestResults/Out/TestFiles before your tests are executed. Remark: MSTest didn’t pick up this change immediately. I had to restart Visual Studio before i

TFS Build: using the built-in editors

By default when editing parameters inside a Team Foundation Build process template you get a very simple editor.(Except for some out-of-the-box available parameters).  But wouldn’t it be nice if you could give your users a much better experience by providing a custom editor? TFS allows you to this by changing the Editor Parameter in the Metadata argument. You could build  your own editor or you could start by using one of the built-in ones(available in the Microsoft.TeamFoundation.Build.Controls assembly). So just enter Microsoft.TeamFoundation.Build.Controls.{ControlName}, Microsoft.TeamFoundation.Build.Controls in the Editor parameter and everything is set. A list of the available designers Editor Description Screenshot BuildAgentSelectionEditor Select a build agent. BuildProjectListEditor Select a project (typically a .sln or .csproj) from source control.

TFS Build: output build results to separate folders

By default TFS Build will redirect the output of your projects to one location(specified by the BinariesDirectory parameter). This means that all DLL’s, executables and so on are available at one place. However the Sharepoint team asked me to change this so that TFS build put each project output into its own folder, instead of dropping all of the files into one flat structure. They wanted the same behavior as in Visual Studio so that the files are available under e.g. Bin\Release, Bin\Debug, etc… This makes it easier for them to run WSPBuilder and create deployment packages. So how can we do this? Open the Build Process template you are using. Drill down until you find the “Run MSBuild for Project” task used to execute the MSBuild process. Set the OutDir property to an empty string. The OutDir property over writes the default output path on each project. By clearing the OutDir property for the MsBuild Activity, Team build will use the Output Path defined in the proje

Could not find a base address that matches scheme net.tcp for the endpoint with binding NetTcpBinding.

Last week I finally got some good news from our server team, the new Windows Server 2008 R2 production server is ready. So I started by installing the first application, but no success. I ended up with the following error message: “Could not find a base address that matches scheme net.tcp for the endpoint with binding NetTcpBinding. Registered base address schemes are [http].” And the related yellow screen of death: The first thing I checked was if non-http activation was enabled. So I went to the Control Panel , clicked on Turn Windows features on or off. There I browsed to the  Microsoft .NET Framework 3.x part and validated if both Windows Communication Foundation HTTP Activation and Windows Communication Foundation Non-HTTP Activation were checked . This was the case so the investigation continued… On the MSDN website I saw that one extra step is required. To support net.tcp activation, the default Web site must first be bound to a net.tcp port. You can do this b

Web Deploy publish/package validating error: Missing or Invalid property value for $(MsDeployServiceUrl)

After installing the new Windows Azure SDK for Visual Studio 2010 , I wanted to try the new Web Deploy features . But when I tried to publish my web application it failed with the following error message: “Web Deploy publish/package validating error: Missing or Invalid property value for $(MsDeployServiceUrl)” On the IIS forums someone mentioned that uninstalling the "Microsoft Web Publishing for Visual Studio 2010" feature should fix the issue. So I went to Add/Remove Programs, selected the "Microsoft Web Publishing for Visual Studio 2010" feature and uninstalled it. After restarting Visual Studio I was finally able to publish using the new Web Deploy.

X-ray goggles

Last week I discovered this nice tool: X-ray goggles . “The X-Ray Goggles make it easy to see and mess around with the building blocks that make up the web. Activate the Goggles to inspect the code behind any web page, from the New York Times to your own blog. Then remix elements with a single click, swapping in your own text, images and more.”   The X-Ray Goggles are a bookmarklet —a special kind of tool that can augment any web page. How to use it? Open  a Firefox, Opera, Chrome or Safari web browser(IE isn’t supported yet). Go to https://webmaker.org/en-US/tools/x-ray-goggles/install/ and follow the instructions. After adding the tool to your bookmarks browse to any side you want. Click on the x-ray goggles button in your bookmarks. You can now hover over any element and see what’s it made off. Just click on it to see the markup and change it anyway you want.
