.NET 6 vs .NET Core

What is NET 6 vs NET core?
.NET 6 is a successor to .NET Core and brings several improvements over its predecessor. Some key differences include:
- Long-term support (LTS): Unlike .NET Core, which had designated LTS releases, .NET 6 is an LTS release, meaning it will receive official support and updates for an extended period, making it a more stable and reliable choice for long-running applications.
- Consolidation of frameworks: .NET 6 aims to unify the .NET ecosystem by merging the functionality of .NET Framework, Xamarin, and .NET Core into a single framework, providing a more cohesive development experience.
- Improved performance and features: These, along with APIs, were not available in previous versions. .NET 6 also includes advancements in areas such as cloud-native development, web APIs, and Blazor.
- Compatibility and migration: While .NET 6 provides compatibility with existing .NET Core applications, migrating to .NET 6 may require some modifications and testing to ensure a smooth transition. Microsoft provides tools and guidance to facilitate this.
When thinking of NET 6.0 vs NET core, or NET core vs NET 6.0, you can consider these before taking the next step.
