Team, we have an existing .Net application which is using owin. now we are upgrading to .Net core. But i am getting messages like

Severity Code Description Project File Line Suppression State Warning NU1701 Package 'Microsoft.Owin 4.2.2' was restored using '.NETFramework,Version=v4.6.1, .NETFramework,Version=v4.6.2, .NETFramework,Version=v4.7, .NETFramework,Version=v4.7.1, .NETFramework,Version=v4.7.2, .NETFramework,Version=v4.8, .NETFramework,Version=v4.8.1' instead of the project target framework 'net6.0'. This package may not be fully compatible with your project.TokenAuthenticationWEBAPI TokenAuthenticationWEBAPI.csproj 1

Could you please confirm the alternative package for .Net core for the below packages Microsoft.Owin.Host.SystemWeb Microsoft.Owin.Security.OAuth Microsoft.Owin.Cors

Thanks.

Microsoft Security | Microsoft Authenticator
Developer technologies | ASP.NET Core | Other

    Asp.net core has owin middleware support:

    https://learn.microsoft.com/en-us/aspnet/core/fundamentals/owin?view=aspnetcore-8.0

    but as suggested, you are probably better better off replacing the owin middleware with native asp.net core middleware.

    OWIN is the predecessor to ASP.NET Core where application features are plugged in rather than every framework feature being available to every application. Essentially, you get to pick and choose the features an application supports.

    One of your question seems to be related to token authentication in Web API Core. Token authentication is configured in middleware. The official documentation covers this concept thoroughly.

    The same applies to CORS. The official documentation illustrates how to handle CORS in an Web API Core application.
