[Hot Reload] Enable hot reloading for Blazor inside an iframe

Open jsakamoto opened this issue 1 year ago • 1 comments

Description

Hot Reload on a Blazor app doesn't work inside an iframe. See the attached video and sample code.

https://github.com/dotnet/sdk/assets/95908/6246ee11-c28a-471b-82d3-0218b1a15605

Sample code: 📦BlazorWasmApp1.zip

The solution I'd like

I know this is intentional by design, as mentioned in the pull request: https://github.com/dotnet/sdk/pull/21954. However, some edge cases exist where hot reloading support inside an iframe is essential. For instance, the clone of Storybook for Blazor, "Blazing Story" (https://github.com/jsakamoto/BlazingStory), requires such ability because it has to host a preview of the story using an iframe.

Therefore, I hope we have a public "escape hatch" API allowing developers to explicitly enable hot reloading inside an iframe for such a particular scenario.
