Closed stambunan closed 4 years ago
If you want it, I'll take a pull request to add it back in. I didn't know that would be necessary or desirable in 3.0
@stambunan could you please share your solution cause I am running into the same problem. tx
this is behavior is only found in upgraded projects not in newly created ones
@jeremydmiller I'll create a PR to add it back in. @wendellmva what I did was I created a static extension class with the above inserted to get it to work.
public static class LamarCustomExtension
{
public static IWebHostBuilder UseLamarForWebHostBuilder<T>(this IWebHostBuilder builder, Action<WebHostBuilderContext, T> configure = null) where T : ServiceRegistry, new()
{
return builder.ConfigureServices((context, services) =>
{
var registry = new T();
configure?.Invoke(context, registry);
services.AddLamar(registry);
});
}
public static IWebHostBuilder UseLamarForWebHostBuilder(this IWebHostBuilder builder, Action<WebHostBuilderContext, ServiceRegistry> configure = null)
{
return builder.UseLamarForWebHostBuilder<ServiceRegistry>(configure);
}
}
which got used in the lambda entry point:
public class LambdaEntryPoint : APIGatewayProxyFunction
{
protected override void Init(IWebHostBuilder builder)
{
builder
.UseLamarForWebHostBuilder()
.UseStartup<Startup>();
}
}
I have a similar (Same) issue, although the workaround above didn't work for me.
This is my code from my .Net Core 3.1 service Program.c
public static void Main(string[] args)
{
CreateWebHostBuilder(args).Build().Run();
//CreateHostBuilder(args).Build().Run();
}
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseContentRoot(Directory.GetCurrentDirectory())
.ConfigureLogging((hostingContext, logging) =>
{
logging.AddConfiguration(hostingContext.Configuration.GetSection("Logging"));
logging.AddConsole();
logging.AddDebug();
})
.UseIISIntegration()
.UseLamarForWebHostBuilder()
.UseStartup<Startup>()
.CaptureStartupErrors(true)
.UseSetting("detailedErrors", "true");
}
I also tried to use it as a standard HostBuilder, and both give me the same error.
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>()
.CaptureStartupErrors(true)
.UseSetting("detailedErrors", "true");
})
.ConfigureLogging((hostingContext, logging) =>
{
logging.AddConfiguration(hostingContext.Configuration.GetSection("Logging"));
logging.AddConsole();
logging.AddDebug();
})
.UseLamar();
}

@segantim That looks like a bi-directional dependency issue? Is there something within your registration that causes A to depend on B and B to depend on A ? My issue was on using Amazon's Custom Runtime library with .NET Core 3.0 as I was trying to deploy a lambda. The custom runtime library only exposes IWebHostBuilder. If IHostBuilder was available, I would be using that.
@stambunan The first code listing (with useLamar() instead of UseLamarForWebHostBuilder()) worked fine under .Net core 2.2. I'm trying to get the code up to 3.1, unfortunately I ran into this. Sorry to jump on the thread, but I suspect it's a similar issue for a few of the bugs, and I thought it might be a waste to open a new bug. It's a standard .Net Core Web Service that does logging / entity framework, there's really nothing tricky or special about the code. I didn't write the code, so I'm a little behind the 8 ball here. There may be something lurking in my code, just not sure what it could be.
@stambunan An update... As part of my startup.cs I have the following code. Once I removed it, it seems to resolve the issue, but I don't know what else this will break. I assume since all the dll's are in this folder, one of them was causing the issue. I'm just unsure how this worked in 2.2 now
services.Scan(s =>
{
s.AssembliesFromApplicationBaseDirectory();
s.WithDefaultConventions();
});
I have a .NET Core 3 Web API that will be deployed in AWS Lambda with an API Gateway connecting to it using proxy integration. The Lambda Entry point requires an override with the following method signature:
protected override void Init(IWebHostBuilder) { builder.UseStartup<Startup>(); }
See https://aws.amazon.com/blogs/developer/net-core-3-0-on-lambda-with-aws-lambdas-custom-runtime/The #if NETSTANDARD2_0 in WebHostBuilderExtensions.cs prevents me from using the helper method. I added it manually into the project and it seems to work properly.
Should a new nuget package be available to allow the usage of UseLamar() with IWebHostBuilder in .NET Core 3 or have a helper method called UseLamarForAWSWebHostBuilder() ?
