OWIN扩展在.NET Core中的OauthauthorizationerverProvider支持？

Question

我们已经从.NET框架迁移到.NET 6，但是转换后，不支持“ Microsoft.Owin.Security.oauth”之类的参考库，因此我无法使用“ OauthauthorizationerverProvider”，我们需要自定义提供商来验证针对AD的凭证，您能帮助您在.NET Core中实现相同的功能，适用于刷新令牌。

除此之外，Owin Cross Platform是吗？如果没有，最新或广泛使用的身份验证机制是什么？

public class AuthorizationProvider : OAuthAuthorizationServerProvider
    {
        

        public AuthorizationProvider()
        {
           // Code
        }

        public override async Task ValidateClientAuthentication(OAuthValidateClientAuthenticationContext context)
        {
            context.Validated();

            // token endpoint is called from configuration service and ui.
            // source parameter added to identify from where endpoint is called
            var source = context.Parameters.Where(f => f.Key == "source").Select(f => f.Value).SingleOrDefault();
            if (source != null && !string.IsNullOrEmpty(source[0]))
            {
                context.OwinContext.Set<string>("source", source[0]);
            }
        }


 public class RefreshTokenProvider : IAuthenticationTokenProvider
    {
        private static ConcurrentDictionary<string, AuthenticationTicket> _refreshTokens = new ConcurrentDictionary<string, AuthenticationTicket>();

        /// <summary>
        /// There are two create methods in this class as interface expects both to be implemented
        /// </summary>
        /// <param name="context"></param>
        /// <returns></returns>
        public async Task CreateAsync(AuthenticationTokenCreateContext context)
        {            
            Create(context);
        }
        }
