Hot Reload and Hot Design Internals

This page focuses on the implementation side of AXSG hot reload and hot design.

Runtime responsibilities

The runtime layers are responsible for:

tracking generated type/source registrations
maintaining include and theme registries
mapping source paths back to generated types and resources
coordinating UI-thread reload application
preserving state where targeted reload can avoid full re-instantiation

Compiler responsibilities

The compiler side must emit stable, deterministic artifacts so hot reload deltas do not destabilize Edit-and-Continue.

Recent work in this area includes:

stable event binding helper names
stable expression helper method emission
deterministic include graph analysis
explicit runtime helper generation instead of anonymous lambdas in emitted code

Tooling responsibilities

Tooling layers coordinate the runtime and compiler through:

dotnet watch graph integration
mobile remote endpoint configuration
language-service diagnostics and editor affordances for hot-reload-related markup surfaces
