Performance Improvements in .NET Core 3.0 

• .NET Core is the future of .NET: If you’ve already started working with .NET Core, that’s great! If you’re starting a new project, you should consider .NET Core.
• .NET Framework will continue to be supported: If you have any existing applications on .NET Framework (Windows-only), you can keep those on .NET Framework.
• .NET Releases will become more predictable: Starting with .NET 5.0, there will be 1 major release every year,  after which each even-numbered release (6.0, 8.0, etc) will come with LTS (Long-Term Support).
