As the .Net developer community continues to evolve, more emphasis is being put on creating applications that are easily maintained and quick to modify. One of the easiest techniques for accomplishing this is to strive for highly decoupled code. As a result, more projects are looking to make use of the Dependency Inversion Principle (DIP) and Inversion of Control (IoC) containers. In this session we will look at the concepts behind DIP as well as a decoupled implementation of an IoC container using Castle Windsor.

Every web application starts out on a single web server. And while we've been told over and over again that you can always move to multiple web servers, it's not as simple as that! This session digs into the details of what it takes to make that leap - all the changes needed to let your application function properly with more than one server. You'll learn about replicating your web application between two servers and how to keep the content in sync. The techniques and challenges of load balancing are explored. And you'll explore the critical challenge of moving to multiple servers - getting rid of affinity. There's more affinity than just the session object, but that is a key starting point. Moving to multiple servers isn't easy, but this session will give you the check list of what to do to be successful.

Although there are many ways to deliver rich Internet applications, jQuery is a library that can be used to deliver the experience using only HTML, CSS and JavaScript. Being one of many web-based libraries, jQuery is one of the most popular and contains a number of plugins that can enhance your website with an amazing user experience. We'll cover cross-browser development as well as mobile development and we'll also compare jQuery to other JavaScript-based libraries out there.

Soap-shmope - CRM developers can use the latest development technologies such as LINQ, ADO.NET Data Services, AJAX, and Silverlight.

This session will demonstrate how multi-touch enabled applications can be used in multiple vertical industries to improve the communication, education, collaboration, and experience overall across the software continuum. The user experience demonstrations will highlight the use of these Microsoft technologies:

• Windows Presentation Foundation (WPF) can be used to visualize data. WPF is the next-generation presentation sub-system for Windows. It provides .NET developers and designers with a unified programming model for building rich Windows smart client user experiences that incorporate UI, media, and documents.
• Windows 7 Touch - Windows 7 offers more choice in how users interact with their PCs, such as through MultiTouch gestures. With WPF support for Windows 7 MultiTouch .NET programmers have a revolutionary new way to build interactive user experiences.
• Microsoft® Silverlight™ is a cross-browser, cross-platform, and cross-device plug-in for delivering the next generation of media experiences and rich interactive applications for the Web. And with its 3.0 version it is multi-touch capable.
• Microsoft Surface is a multi-touch product from Microsoft which is developed as a software and hardware combination technology that allows a user, or multiple users, to manipulate digital content by the use of natural motions, hand gestures, or physical objects by the use of natural motions, hand gestures, or physical objects.

WCF RIA Services provides a way to quickly construct n-tier solutions for Silverlight client applications, reducing the amount of manual service defintion and hookup and duplication of code that often results in building such a solution manually. This ses Silverlight 3 introduced Out-Of-Browser and Offline Support. Silverlight 4 goes way beyond "Out of the Browser" and into the realm of "On to the Desktop" with a littany of desktop application features: Webcam & Microphone support, Copy & Paste to the OS, Drag & Drop from the desktop, Mouse wheel and right click context menu support, Printing, html hosting, Toast Notifcations, and utilizing desktop assemblies without recompilation. Silverlight 4 also includes a trusted application model to escalate permissions to access local documents, execute desktop applications, COM automation and with the support of Group Policy to manage and control which applications can receive this trust. At the end of this session you'll be both inspired by the possibilities of Silverlight 4 and thoroughly confused at the blurred line between WPF and Silverlight.

This session will be heavily demo focused to accentuate how the power of the Windows Presentation Foundation (WPF) and Microsoft Silverlight can be used to visualize data to produce amazing software. WPF is the next-generation presentation sub-system for Windows. Silverlight is a broad reach sub-set of WPF that runs cross platform in the browser. These two XAML based developer technologies provide developers and designers with a unified programming model for building rich Windows client and RIA (Rich Internet Application) user experiences that incorporate UI, media, and documents. WPF & Silverlight use vector based graphics rendering, which results in better graphics and presentation for an application. WPF & Silverlight also has other consistent features such as layout, styling, and data binding, which, when you mix with interactivity, enables scenarios such as interactive data visualization. When you put all this together, you have a unified API for various presentation components, such as 2D and 3D documents and declarative programming through XAML, which is a powerful platform for data visualization that can be used to really “light-up” you enterprise and Internet applications. These XAML based developer technologies are manifested in 3 major application platforms (Windows Client (WPF), Silverlight & Microsoft Surface) and all will be covered in this session at some level.

Architecting and building a Software as a Service application requires solving a series of problems that are independent of a particular software platform. First, a SaaS architecture follows directly from the fundamental principles of the business model. Second, a series of difficult technical problems must be solved in addition to providing the business functionality. These include certificate security, low-IT-capable clients, business continuity when connectivity is lost, high availability, adjusting to elastic demand (both scaling up, or scaling down), provisioning of services, scalability as the number of clients increase, database design for clients, thin vs thick clients, how to use virtualization, and how to integrate and release service functionality over several different client applications. Third, you have to effectively use the platform technology such as WCF and ASP.NET, or Windows Azure. This talk discusses how to architect and design a SaaS application.

What is Command And Query Separation, why would we want to have that kind of architecture ? How do we build such a system, what do we have to think about ? What would it look like ? Is it expensive ? is it scalable ? is it efficient ? Come and hear what nVentive's Erik Renaud has to say on the subject, and how they are building next generation systems upon these principles.

The primary focus of CSLA .NET is to help in the creation of a rich object-oriented business layer that expresses the needs of the business domain model. CSLA objects provide rich databinding, validation and authorization making them a logical choice for today's business applications and services. This talk will provide an introduction to CSLA.

This presentation has been designed to give you a head start in modularity practice with a layered architecture. As has been said by Albert Einstein, "Everything should be made as simple as possible, but not simpler." Test-Driven Architecture (TDA) substantially reduces the intrinsic complexity of a layered architecture by adding explicit contracts between the layers. Using practical examples, this presentation demonstrates how to apply “test-driven” design techniques to define the visible interface of a layer. The goal of TDA is to provide an abstraction, the architecture tests, which make possible to create a new semantic level to be more precise with regard to the contract of a layer. This precision is important to effectively communicate to the programmers the detail architecture and also to adequately validate the implementation. One of the major benefits of TDA it is that since tests are executable, correctness with regard to architecture can be confirmed at any time. Overall, you will acquire fundamental knowledge about how to add a visible and testable interface to your layers.

The session will cover a few basic scenarios, and move to more full-feature line-of-business and social applications that leverage the best of these platforms.

The Visual Studio and Office teams have made significant investments in improving the developer experience for building and deploying Office and SharePoint applications. In this demo-heavy session, we will walk through an end-to-end business application built on Office and SharePoint and discuss architecture options to consider when building these systems. You'll learn how to use Visual Studio and it’s enhanced set of RAD tools that allows users to consume external line-of-business data within the familiar Office UI. See how new language enhancements will make developers more productive whether they write their code in VB or C#. Finally, you’ll learn how Visual Studio 2010 makes it possible to provide a more seamless end-user deployment experience for Office solutions.

MOSS 2007 Search is conventionally used for indexing and searching for documents and web pages in SharePoint, file shares, and web sites, but it is very rarely ever used for other entities like products, inventory, customers, employees, and other data that can be structured in XML. We will spend the first half of our session providing a technical overview of the Microsoft search stack – Microsoft Search Server Express vs. Microsoft Search Server vs. MOSS 2007 search vs. FAST search which we will only touch on briefly. The second half of the session will dive in to demonstrate end-to-end how you can get the most out of search by indexing and displaying XML content, independent of data source and free using Microsoft Search Server Express 2008. We will also discuss Search as a Service and the general pitfalls to watch out for.
