When is end of life for dotnet framework 4.5.2

Question

We have close to 30 apps running on .net framework 4.5.2

Can someone explain the following paragraph from Microsoft site (https://support.microsoft.com/en-us/help/17455/lifecycle-faq-net-framework) in simple terms

It says "Beginning with version 4.5.2 and later, .NET Framework is defined as a component of the Windows operating system (OS). Components receive the same support as their parent products, therefore, .NET Framework 4.5.2 and later follows the lifecycle policy of the underlying Windows OS on which it is installed. "

If we keep upgrading our Windows server OS, will there ever be a need to upgrade the framework? I assume Microsoft will keep sending security patches for 4.5.2.

UPDATE

Microsoft just announced end-of-life for .NET 4.5.2, 4.6, and 4.6.1: April 26, 2022.

Original Post

See this page for what OS versions are supported for each .NET version: https://learn.microsoft.com/en-us/dotnet/framework/get-started/system-requirements

From how I understand it, .NET 4.5.2 goes out of support when Windows 8.1 goes out of support, as it is the last Windows OS where .NET 4.5.2 is officially supported.

Therefore, .NET 4.5.2 goes out of support on January 10, 2023.
