We choose ASP.NET because our core business is working with the SAP HANA database using SAP Business One. We can develop state-of-the-art applications with Razor and Visual Studio 2022 fast and with excellent application performance response. Working SAP Hana with JAVA could be more challenging because it has fewer developers communities, and it could be harder to find a solution for a question.
