ASP.NET Core Blazor uses the generic app hosting in ASP.NET Core 3+ but the two hosting models have slightly different integrations.
Server-side implementations are configured in exactly the same way as any other ASP.NET Core 3 application.
Client-side injection is slightly more restricted due to requirements for WebAssembly hosting.
This example for WebAssembly works as of March 30, 2021 with .NET 5. Example:
csharp
public class Program { public static async Task Main(string[] args) { var builder = WebAssemblyHostBuilder.CreateDefault(args); builder.ConfigureContainer(new AutofacServiceProviderFactory(ConfigureContainer));
builder.RootComponents.Add<App>("#app");
await builder.Build().RunAsync();
}
private static void ConfigureContainer(ContainerBuilder builder) { // add any registrations here }
}
Once registered, Blazor components can use dependency injection via the standard @inject Razor directive.
