Full summary based on description

What’s changing in .NET 11 Blazor virtualization

• The session previews virtualization improvements planned for .NET 11 in Blazor.
• The focus is on making the Virtualize component work better in real-world UI scenarios.

Variable-height items in Virtualize

• The presenters discuss adding support for variable-height items when using the Virtualize component.
• This targets lists where rows/cards don’t have a uniform height, which can be difficult to virtualize efficiently.

Scroll position control APIs

• The session also introduces new APIs for controlling scroll position.
• This is aimed at scenarios like:
  • Programmatically scrolling to a specific item
  • Preserving/restoring scroll position
  • More predictable scrolling behavior in virtualized lists
