1. What is the Microsoft Support Lifecycle policy for .NET Framework?
2. What is a component?
3. When does .NET Framework 4.5.2 reach end of support?
4. Why did the support for .NET Framework 4, 4.5 and 4.5.1 end on January 12, 2016?
5. Does this support change affect any previous versions of .NET Framework such as .NET Framework 3.5 SP1?
6. Will I need to recompile/rebuild my applications to make use of .NET Framework 4.5.2?
7. Are there any breaking changes in .NET Framework 4.5.2? Why do you include these changes?
8. The .NET Framework is also middleware in other Microsoft products such as Exchange Server, SQL Server, Dynamics CRM, SharePoint, and Lync. Do I need to make any updates to these products if they are using .NET 4, 4.5, or 4.5.1?
9. When I installed Visual Studio, it installed a version of the .NET Framework. Does this mean the version of .NET Framework that came with Visual Studio takes the Support Lifecycle of Visual Studio?
10. What is the Support Lifecycle policy for the different versions of .NET Framework?
