제가 2017년에 구입한 v17.2.3 버전조차도 VS2019를 지원하지 않으며,
개발업체에 문의해봐도 그냥 안된다고만하고, vs2017을 사용하거나 새 구독 버전을 구입하라고 했습니다.
We added support for Visual Studio 2019 only starting with DevExpress version 18.1.11 and higher. Refer to the Shipping Versions & Supported Technologies page and Visual Studio 2019 Support blog post for more information.
Thus, you need to either renew your subscription to get access to the newest DevExpress versions in which Visual Studio 2019 is supported or utilize Visual Studio 2017.
