• EF Core 5.0 runs on .NET Core 3.1; it does not require .NET 5.
  • This may change in future previews depending on how the plan for .NET 5 evolves.
• EF Core 5.0 runs on other platforms that support .NET Standard 2.1.
• EF Core 5.0 will not run on .NET Standard 2.0 platforms, including .NET Framework. 

• New responsive containers! Over a year in the making, fluid up to a particular breakpoint, available for all responsive tiers.
• New responsive .row-cols classes for quickly specifying the number of columns across breakpoints. This one is huge for those of you who have asked for responsive card decks.

.NET Core 3.1 is a long-term supported (LTS) release (supported for at least 3 years). We recommend that you move any .NET Core 3.0 applications and environments to .NET Core 3.1 now. It’ll be an easy upgrade in most cases.
