# Microsoft Product Life Cycle

軟體產品的支援期限對資安是重要的考量，而以.Net為主的開發架構下，查詢微軟產品的生命週期是很重要的資訊。

### .Net 生命週期

[.Net Framework的生命週期](https://docs.microsoft.com/en-us/lifecycle/products/microsoft-net-framework)  

[Microsoft .NET and .NET Core的生命週期](https://docs.microsoft.com/en-us/lifecycle/products/microsoft-net-and-net-core)

> .Net Framework 4.8 生命週期還是要看OS支援，所以目前還沒End Date
.NET Framework 4.8: Support for .NET 4.8 **follows the Lifecycle Policy of the parent OS**. It is supported as a Windows component on the latest required update for the operating systems below. We recommend customers upgrade to .NET Framework 4.8 to receive the highest level of performance, reliability, and security.

此網址可以查詢到微軟產品的生命週期，像Windows Server、.Net、Office等的支援的終止日，
對判斷作業系統或元件升級很好用。
但有些會因為後來再出Service Package而將支援終止日往後延，
所以也不需過早升級。
