Performance, reliability, and diagnostics Enterprises running mission-critical workloads value the mature performance and diagnostics story in .NET Framework 4.8:

Profiling and diagnostics: Existing profilers, ETW tracing, Windows Performance Recorder (WPR), and Event Tracing for Windows integrate well with 4.8. The CLR provides diagnostic APIs and performance counters to monitor throughput, GC behavior, threadpool activity, and JIT metrics.

TLS and cryptography: Security updates include support for modern TLS protocols and cipher suites, along with alignment to Windows’ crypto stack. This makes .NET Framework 4.8 better positioned to meet contemporary security standards and interoperability with modern TLS servers.

If you need to install it manually, always use official Microsoft sources: Determine which .NET Framework versions are installed

One of the most technical upgrades in version 4.8 is the integration of a based on .NET Core 2.1. This brings modern performance optimizations and bug fixes to legacy applications, resulting in faster execution times and more efficient memory management. Additionally, memory management for Native Image Generator (NGEN) images was improved to reduce the system's attack surface, preventing unauthorized code execution in certain memory regions.
