Radzen contains all the features that Visual Studio LightSwitch developers need to make modern web applications.

LightSwitch end of life - what to migrate to
Visual Studio LightSwitch has no Microsoft successor, leaving teams with a dead-ended but business-critical app. Radzen Blazor Studio is a practical path off it: connect the same database, regenerate the screens as modern Blazor pages, and extend them in standard C#.
Replace WinForms and WebForms, one module at a time
Migrating from WinForms or ASP.NET WebForms does not have to be a big-bang rewrite. Reuse your existing database, generate Blazor screens for the data-driven parts, and run new modules alongside the older system so delivery never stops.
Reuse the data you already have
Your database is the part worth keeping. Radzen connects to it directly, handles complex data scenarios, and generates maintainable Blazor screens on top - so modernization is about the UI and the platform, not migrating your data.
Modernize without a new lock-in
Keep the code you own
The modernized app is standard C# and Razor in your repository - no proprietary runtime, nothing to rip out if you leave. You are not trading one dead-end platform for another.
Deploy where the old app ran
Blazor runs wherever .NET runs - your cloud, on-premises or air-gapped. Modernize an internal system without exposing its data or changing where it lives.
Incremental, not big-bang
Run new Blazor modules next to the legacy system and migrate module by module. Delivery keeps moving while the old app stays available.
Frequently Asked Questions
Visual Studio LightSwitch has no Microsoft successor. Radzen Blazor Studio is a practical path off it: connect the same SQL database, regenerate the screens as modern Blazor pages, and extend them in standard C#. Radzen contains the features LightSwitch developers need to build modern web applications.
Yes. Reuse your existing database and business logic, generate Blazor screens for the data-driven parts, and move workflows over incrementally so the legacy system keeps running while you migrate.
No. Modernize incrementally - run new Blazor modules alongside the older system, reusing the existing database, and replace workflows module by module instead of a big-bang rewrite.
No. Radzen generates standard C# and Razor you own, with no proprietary runtime and no per-app fees. Deploy the modernized app wherever the legacy one runs, and it keeps building with or without Radzen.
After the end of the LightSwitch lifecycle, TAL Engineering rebuilt a company-wide ERP in Radzen - 7+ enterprise modules, maintained by their process team, with legacy and modern modules coexisting through the migration.
