Course description

A practical course on modernizing .NET applications. You’ll learn to plan the move from .NET Framework to .NET 8 (and beyond), choose the right strategy, and make changes step by step without rewriting the whole system at once.

We’ll cover in-place and side-by-side migrations, the data layer (EF6 → EF Core), API and web service migration (WCF/Web Services → REST/gRPC), moving authentication (Forms Auth → ASP.NET Core Identity), and UI modernization (Web Forms → Blazor or DotVVM).

You’ll get clear procedures, best practices, and tips for handling technical debt, testing, and architecture.

About agenda

What you'll get?

A clear plan to estimate effort, split work, and explain benefits to management.

Guidance on when to use in-place (DotVVM) versus side-by-side (Blazor + YARP)

Backend migration covering WCF/Web Services to REST or gRPC, SignalR updates, and EF6 to EF Core with ADO.NET implications.

Identity and security that move Forms Authentication to ASP.NET Core Identity and migrate users and roles safely.

Architecture and UI improvements that move Web Forms to Blazor or DotVVM, share auth/session with System.Web.Adapters, run two apps in parallel, add tests, and reduce technical debt.
