Microsoft .NET Framework 3.5 for Windows

Microsoft .NET Framework 3.5 is a managed runtime and development environment that executes applications across desktops while providing extensive libraries and APIs for web, desktop, and service-oriented solutions. It integrates improvements to the Common Language Runtime (CLR), Windows Presentation Foundation (WPF), ASP.NET, Windows Communication Foundation (WCF), and ADO.NET components.

Microsoft .NET Framework 3.5 introduces dynamic data scaffolding for ASP.NET, enhanced graph serialization and SQL Server 2008 support in Entity Framework, and expanded LINQ capabilities. It also includes an updated Data Services Framework for exposing REST-based data endpoints and support for ClickOnce deployment and system updates.

Faster, stronger .NET

Microsoft .NET Framework 3.5 incorporates optimizations within the CLR, including improved startup performance, refined native image layout, and automatic ASLR opt-in for enhanced memory management on supported systems. Managed code executed from network shares now runs with complete trust by default. Strong-name verification opt-out is endorsed for fully trusted assemblies. These changes target runtime efficiency, application execution performance, and deployment reliability, while maintaining backward compatibility with existing .NET assemblies.

The framework expands developer-facing APIs across multiple domains. ASP.NET introduces Dynamic Data scaffolding for rapid web data applications and enhanced AJAX history management. WPF gains support for DirectX pixel shaders, native splash screens, improved bitmap rendering performance, and new business application features, including the WebBrowser control. ClickOnce deployment receives new publisher options, including customized branding and opt-out signing configurations. However, it's dependent on the Microsoft-managed update framework for maintenance.

It strengthens ADO.NET and WCF capabilities. LINQ to SQL expands to support new SQL Server 2008 features, while ADO.NET Data Services Framework introduces REST-based data exposure for relational and conceptual models. These services integrate directly with the Entity Framework, enabling LINQ-based queries and simplified updates from .NET clients. WCF enhancements extend DataContract Serializer support, improve debugging under partial trust scenarios, and broaden syndication protocol handling for web-based applications. 

Performance plus

The Microsoft .NET Framework 3.5 serves as both a runtime and a comprehensive set of application libraries designed to enhance performance and developer productivity. Its major components include CLR runtime improvements, updated ASP.NET web development features, extended WPF visualization capabilities, and strengthened ADO.NET and WCF data services. It provides optimized application execution, broader API integration, and enhanced support for SQL Server 2008, as well as REST-based data access.
