[severity:It's more difficult to complete my work] [regression] [worked-in:17.13]
I have a default Blazor app in .NET 10 RC 2 in VS 26 and while trying to build it or run it or publish it I get this error:
The JS module file 'C:\Users\X\source\repos\ProjectApp\ProjectApp\publish\wwwroot\Components\Layout\ReconnectModal.razor.js' was defined but no associated razor component or view was found for it.

Thanks for contacting us.

From what I can tell you have published your app to the publish folder inside of your project folder. For that to work you should exclude the publish folder from the list of default content items, otherwise subsequent builds will find those files and try to process them, which is what I suspect is happening based on the error message.

Thanks yes this was the issue! I was confused because I started getting it just with VS26 and .NET 10. Thanks again!
