.NET 5: Support for isolated CSS in Blazor WebAssembly #91

Closed ChristianWeyer closed 3 years ago

ChristianWeyer commented 3 years ago

Hi!

I know that you are still working on .NET 5 support. It would be great and very helpful if you could look into supporting live reloading changes in isolated CSS files in Blazor WASM. Those changes need a compile step to happen.

Thanks.

Hi @ChristianWeyer

Good news! Support for isolated CSS hot-reload is coming in the new version. I'm already testing it locally, so it should be available in a few days.

ionoy commented 3 years ago

Isolated CSS support is included in 1.6.17. Please see if it works in your case.

Just tried it, get this exception:

Can you check if any of these files exist?

ChristianWeyer commented 3 years ago

Nope, they are not there:

Most probably, as in this class lib there are no scoped CSS files.

BTW. the entire sample is here: https://github.com/thinktecture/blazor-webassembly-demo/tree/net5-rc2

ionoy commented 3 years ago

Thanks for the sample! This will make it easier.

ionoy commented 3 years ago

Please try this build when you have time. It should fix the issue.
