you should either use the using statement, or let the DI container handle disposing objects for you. For cases where that's not possible, ASP.NET Core provides two mechanisms you can hook in to: RegisterForDispose and IApplicationLifetime.

The first preview of Entity Framework Core (EF Core) 8 is available on NuGet today!

Basic information

EF Core 8, or just EF8, is the successor to EF Core 7, and is scheduled for release in November 2023, at the same time as .NET 8.

EF8 currently targets .NET 6. This will likely be updated to .NET 8 as we near release.

EF8 will align with .NET 8 as a long-term support (LTS) release. See the .NET support policy for more information.

Test OAuth 2.0 requests and debug responses

There's two ways to deploy a .NET Core application. There's FDD and SCD. Since TLAs (three letter acronyms) are stupid, that's Framework-dependent and Self-contained. When .NET Core is installed it ends up in C:\program files\dotnet on Windows, for example. In the "Shared" folder there's a bunch of .NET stuff that is, well, shared. There may be multiple folders, as you can see in my folder below. You can have many and multiple installs of .NET Core.
