It is a pretty simple Task, I want to use images in my razor pages which are located in wwwroot/css/images and use it in html like this.
<img src="~/css/images/logo.png"/>
In a normal ASP.Net Core application I would just add app.UseStaticFiles() in the Configure method, but since this is a blazor hosted application, it changes nothing.
I also tried adding the app.UseStaticFiles() in the server project, but with no success either.
If you want to try it out yourself just create a blazor-hosted project from the templates and try to serve/display images like I did.
