Issue in converting Microsoft.AspNetCore.WebHost to Microsoft.Extensions.Hosting.Host #64446
Description
My application has code like below to set up an ASP.NET Core host using WebHost (.NET 8.0):
public class WCFServiceHost
{
private void SetupHttpWebHost(Uri[] baseAddresses)
{
var builder = Microsoft.AspNetCore.WebHost.CreateDefaultBuilder()
.ConfigureServices(x => x.AddSingleton(this))
.UseStartup<Startup>();
builder.Build().RunAsync();
}
}
internal class Startup
{
public Startup(WCFServiceHost wcfServiceHost)
{
}
}
Since WebHost becomes obsolete in .NET 10, I try to convert it to using Host with the code like below:
public class WCFServiceHost
{
private void SetupHttpWebHost(Uri[] baseAddresses)
{
var builder = Microsoft.Extensions.Hosting.Host.CreateDefaultBuilder()
.ConfigureServices(x => x.AddSingleton(this))
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>();
});
builder.Build().RunAsync();
}
}
However, the application is getting
System.InvalidOperationException : Unable to resolve service for type 'WCFServiceHost' while attempting to activate 'Startup'. error.
I appreciate if someone can provide guidance about the right way of using Microsoft.Extensions.Hosting.Host.
