How do I migrate ASP.NET Global.asax application lifecycle events to ASP.NET Core?▼

Migrating ASP.NET Global.asax lifecycle events to ASP.NET Core involves converting Application_Start, Application_End, and other event handlers to their Core architecture equivalents to align with the new framework's startup pipeline.

What is the best way to convert Application_Start from Global.asax to ASP.NET Core?▼

Converting Application_Start from Global.asax to ASP.NET Core requires moving initialization logic into the new application startup pipeline, replacing the legacy event handler with Core's equivalent lifecycle mechanism to ensure proper execution.

Can I automate code conversion for Global.asax events when upgrading to ASP.NET Core?▼

Automating code conversion for Global.asax events during an ASP.NET Core upgrade is supported, reducing manual migration work by automatically moving and replacing application lifecycle code to align with Core architecture.

When do I need to replace Global.asax during an ASP.NET Framework to Core transition?▼

Replacing Global.asax is needed during an ASP.NET Framework to Core transition when your application relies on lifecycle events, requiring conversion of these handlers to Core equivalents to maintain functionality in the new architecture.
