Excelente noticia!!! Microsoft esta comprometido con las inversiones en herramientas de desarrollo, esta vez, ya se liberó el Beta 1 del Service Pack 1 para Visual Studio 2008 y el .NET Framework 3.5 muchos de los cambios están basados en la información que enviaron los socios y clientes de Microsoft, principalmente veremos mejoras en la velocidad, estabilidad y nuevas caracterísicas (incluyendo el soporte para SQL 2008 de manera nativa!!!), aquí abajo pueden ver los detalles de las mejoras, para descargarlo pueden entrar a esta liga http://msdn.microsoft.com/es-mx/vstudio/products/cc533447(en-us).aspx
Visual Studio 2008 Service Pack 1 includes:
- Improved designers for building WPF applications
- Full support for SQL Server 2008
- The introduction of the ADO.NET Entity Designer
- Visual Basic and Visual C++ components and tools (including an MFC-based Office 2007 style 'Ribbon')
- Improvements to Team Foundation Server to respond to customer feedback on version control usability and performance, improved e-mail integration with work item tracking and full support for hosting on SQL Server 2008
The .NET Framework 3.5 Service Pack 1 includes:
- Performance increases between 20-45% for WPF-based applications - without having to change any code
- WCF improvements that give developers more control over the way they access data and services
- Streamlined installation experience for client applications
- Improvements in the area of data platform, such as the ADO.NET Entity Framework, ADO.NET Data Services and support for SQL Server 2008's new features.
Windows Presentation Foundation (WPF) and Visual Designer Changes
- Cold startup performance improvement ranging between 20-45% depending on application size without needing to modify any code.
- Additional WPF features for text, graphics, and media to deliver better performance. For example, effects like DropShadow and Blur were implemented using software rendering; with Service Pack 1 these are now implemented using hardware acceleration. Other examples include:
- Text, especially when used in Visual and DrawingBrush, is substantially faster.
- Data scalability improvements - Container Recycling, TreeView virtualization, and more to enable richer data editing support
- Media performance improvements
- A much improved WriteableBitmap that enables real-time bitmap updates from a software surface
- Visual Studio 2008 introduced a brand new designer for WPF applications. Since Visual Studio 2008 released many additional features have become available for inclusion in the designers. These include event tab support within the property grid for control events, toolbox support within source mode, and a variety of other common asks and improvements.
Windows Communication Foundation (WCF) and Workflow Foundation (WF) Changes
- New Hosting Wizard for WCF Service projects.
- Enhancements in Test Client such as support for RM Sessions, Message Contract and Nullable<T> types enables testing of broader set of WCF-based services.
- Expanding reach of DataContract Serializer by relaxing the need of having [DataContract]/ [DataMember] on types and by supporting an interoperable mechanism for dealing with object references.
- Improved Partial Trust Debugging Experience with support for Event Log.
- Support for ADO.NET Entity Framework entities in WCF contracts.
- Improvements in writing REST based services ranging from easily supporting ServiceDocuments publication and consumption to providing greater control and usability of UriTemplate.
- Significant performance improvements on large workflow-based projects in Visual Studio.
- Considerable scalability increases for hosted WCF services in IIS7-integrated mode.
.NET Framework 3.5 Optimized Client Runtime
.NET Framework 3.5 SP1 provides an install version of the .NET Framework optimized for client development. The expected final size of this optimized runtime is less than 20 MB.
New ADO.NET Data Features
.NET Framework 3.5 SP1 includes two new frameworks, the ADO.NET Entity Framework and ADO.NET Data Services framework, to provide developers with greater flexibility and options when creating applications that access and use data.
ADO.NET Entity Framework
The ADO.NET Entity Framework is the next evolution of ADO.NET, raising the level of abstraction at which programmers work with data, and allowing the database structure or data source to evolve without significant impact to the application code.
Rather than coding against rows and columns, the ADO.NET Entity Framework allows the definition of a higher-level Entity Data Model over your relational data, and allows developers to then program in terms of this model. Developers get to deal with the data in the shapes that make sense for the application, and those shapes are expressed in a richer vocabulary that includes concepts like inheritance, complex types, and explicit relationships.
Use LINQ to Entities with the Entity Framework for queries that help create easy to maintain code that retrieves and works with strongly typed data objects or business entities.
ADO.NET Data Services
The Microsoft ADO.NET Data Services framework provides a first-class infrastructure for developing the next wave of dynamic internet applications by enabling data to be exposed as REST-based data services that can be consumed by client applications (e.g., ASP.NET, AJAX, and Silverlight) in corporate networks and across the internet. Easily build applications using a comprehensive set of Microsoft .NET libraries and client components, accessing data through uniform URI syntax and using standard HTTP verbs to operate on the resource.
ADO.NET Data Services provides a framework to build data services for relational data sources, such as Microsoft SQL Server, MySQL, DB2, and Oracle, using the built-in support for the ADO.NET Entity Framework, or for non-relational data sources using the pluggable provider model.
Team Foundation Server Improvements
A number of improvements and additional features have been added to Visual Studio Team System 2008 Team Foundation Server including:
- Simplified the user experience through cleaner "Add to Source Control" dialogs, drag and drop support to the Source Control Explorer and a much easier to use "Workspace" dialog for working folder mappings.
- Version control now automatically supports non-solution controlled files.
- Various changes to the Source Control Explorer such as a new checkin date/time display column, local path hyperlink support and en editable source location field.
Work Item Tracking
- Microsoft Office 2007 integration is now done using the standard Office "Ribbon" delivering a cleaner and easier to use integration to the different Microsoft Office 2007 products.
- E-mail integration for work items and links for Team system Web Access to make it easier to use e-mail as part of the development life cycle.
Visual SourceSafe Migration Tool
- The migration tool has been dramatically improved through many performance and reliability improvements. In addition Service Pack 1 provides support for the elimination of namespace conflicts, automatic solution rebinding, improves timestamp coherency and increases the amount of migration logging information available.
Performance and Scalability
- With Service Pack 1 a large part of the focus was to improve the performance and scalability of Team Foundation Server through changes such as faster synchronization with Active Directory, improved checkin concurrency, a faster way to create source tree branches, online index rebuilding for less maintenance downtime and better support for very large checkin sets.
- Improvements in the number of projects a server can support that make not only the scalability of the server better but also the client experience when connecting to a server with a large number of projects on it.
- Support for using SQL Server 2008 with Team Foundation Server.
- Team System Web Access provides "live" links to work items and checkin e-mail messages. This improves the customer experience for users who do not use Team Explorer.
- Scripting support for the creation of Team Projects.
