It seems in a standard Blazor server app, the _content folder items are not being referenced correctly for anything other than the Development environment. As an example, this reference fails in any non-dev environment:
from _Host.cshtml:
<link href="_content/Blazored.Typeahead/blazored-typeahead.css" rel="stylesheet" />
To Repro, using Blazored-toast lib as an example (but any static file refs seem to have this issue):
Create a new Blazor Server project (dotnet new blazorserver)
What am I missing that would allow this reference to work in other environments?
Consuming static assets from a Razor Class Library works out of the box when the application gets published. You just have to include the static content via <link href="..." />
as you did.
However, when running the app from the build output (dotnet run) or via F5 in Visual Studio you have to ensure that the StaticWebAsset feature is enabled for the given environment.
It is enabled by default for the development environment only. You can turn on the feature unconditionally by ensuring you called UseStaticFiles
and calling UseStaticWebAssets
in the Program.CreateHostBuilder
.
So, ensure that you consuming app has :
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
...
app.UseStaticFiles();
...
}
and in your Program.cs you should have
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStaticWebAssets();
webBuilder.UseStartup<Startup>();
});
