In order to provide greater clarity around the Support Lifecycle of the .NET Framework, Microsoft announced “a Support Lifecycle policy for .NET Framework—states that beginning with .NET Framework 3.5 SP1 the .NET Framework will be defined as a “Component”. As a Component, .NET version 3.5 SP1 will assume the same Support Lifecycle policy as its parent product or platform.” “What does this mean in practical terms? It means that with .NET 3.5 SP1 and later, one simply needs to know if their version of Windows is supported. As a Component, .NET takes the exact same Support Lifecycle as the parent product. In addition, we’re ending support for earlier iterations of .NET 3.0 and 3.5—but are giving customers a year to migrate before ending support. We’ll require all customers to be on .NET Framework 3.5 SP1 or later, by April 12th, 2011 in order to obtain security updates or support,” noted Microsoft.
