PWA in Blazor

I wonder why pwa is not supported in blazor and if its in the roadmap? Being able to run as pwa app is important for our next project.
Is there a workaround to make PWA work in Blazor, like removing some components?

Yes, we plan to add PWA support. It's actually added however this issue is holding us to release it:

Would it work if we just add this line

Will it get automatically fixed on the next .net core release?

It will be better to ask Microsoft - we have no idea. Until this is released we will unable to turn on PWA support.
