If you actually meant a different version (e.g., 4.0.3019 — which does not exist in official Microsoft releases), please clarify the exact build number.

.NET Framework 4.8 (last supported 4.x version) or modern .NET (6/7/8/9) for active support, performance, and cross-platform capabilities.

I believe you may be referring to (not 3019). The number 4.0.30319 is the original release version of .NET Framework 4.0 that shipped with Visual Studio 2010 and Windows Server 2008 R2 SP1.
