VB.NET vs .NET Core: should you modernize or rewrite?
Migrating from VB.NET to .NET Core offers performance, security, and future platform opportunities, but often requires rewriting code, especially because VB.NET support in .NET Core is limited and many APIs differ. Modernise existing apps when preserving code and logic is most important and workloads are manageable during the upgrade process. Rewrite when long-term maintainability, optimal performance, and access to new .NET Core features are priorities. Assess effort, risk, and business value before making a decision.
