Describe the bug

When having (space, dash, underline) in project name, CSS Isolation won't work. Tested by an empty ASP.NET Core MVC project with .NET 6. First made a project named "MVC CSS-Isolation" but it didn't work and getting error "MVC_CSS_Isolation.css 404 not found" in browser console. After that, made another project name "MVCIsolation" and CSS Isolation worked fine.

@Kazem-ma79 thanks for contacting us.

That's likely an inconsistency between the code generated by the template and the actual CSS generated file. I suspect that if you change the file to MVC CSS-Isolation.styles.css in _Layout.cshtml things will work.

@CoderLittleChen I would suggest a similar solution to what's described https://github.com/dotnet/aspnetcore/issues/40668#issuecomment-1066648408. Update the code in the generated template to match the project name.
