You can use this graph api to get all the groups the user is a direct member of.

GET /me/memberOf

In .net-core you can use GraphServiceClient to call graph api. Here is a sample for your reference.

var graphClient = new GraphServiceClient(
                new DelegateAuthenticationProvider(
                    (requestMessage) =>
                    {
                        // Get back the access token.
                        var accessToken = "";

                        if (!String.IsNullOrEmpty(accessToken))
                        {
                            // Configure the HTTP bearer Authorization Header
                            requestMessage.Headers.Authorization = new AuthenticationHeaderValue("bearer", accessToken);
                        }
                        else
                        {
                            throw new Exception("Invalid authorization context");
                        }

                        return (Task.FromResult(0));
                    }
                    ));
            var groups = graphClient.Me.MemberOf.Request().GetAsync().Result;
