Microsoft .NET Framework 3.5 SP1 for Windows® Embedded Point of Service 1.1 Service Pack 3 is now available on the ECE. This update should not be used with any other operating system.
On March 25, 2010 Microsoft announced a revised policy around support for .Net framework 3.5 SP1. With that change the support for .Net Framework 3.0 and 3.5 ends on April 12, 2011 - customers are strongly recommended to migrate to .Net Framework 3.5 SP1 before that date.
To maintain support for embedded customers after the end-of-life for existing components, the Windows Embedded support policy has been changed to allow .Net Framework 3.5 SP1 support for Windows XP Embedded SP3 and Windows Embedded for Point of Service 1.1 SP3.
The .NET Framework is Microsoft's comprehensive and consistent programming model for building applications that have visually stunning user experiences, seamless and secure communication, and the ability to model a range of business processes.
.NET Framework 3.5 Service Pack 1 is a full cumulative update that contains many new features building incrementally upon .NET Framework 2.0, 3.0, 3.5, and includes cumulative servicing updates to the .NET Framework 2.0 and .NET Framework 3.0 subcomponents.
