Super-small and super-simple library for registering classes with the ASP.NET Core IServiceCollection
using attributes.
GitHub: https://github.com/tobysmith568/di-attributes NuGet: https://www.nuget.org/packages/DiAttributes
Classes can be registered as any of these three types of dependency via the respective attributes:
using DiAttributes;
[Scoped]
public class MyService
{ ... }
This is the equivalent of having the following in your Startup.cs
:
services.Scoped<MyService>();
You can also pass in a type as an argument to register the class against:
using DiAttributes;
public interface IMyService
{ ... }
[Scoped(typeof(IMyService))]
public class MyService : IMyService
{ ... }
This is the equivalent of having the following in your Startup.cs
:
services.Scoped<IMyService, MyService>();
The use of these attributes will require you to add the following line once to your Startup.cs
file:
services.RegisterDiAttributes();
Classes can be automatically bound to sections of your app's configuration using the [Configuration]
attribute.
If your appsettings.json
looks like this:
{
"Outer": {
"Inner": {
"MySetting": "My Value"
}
}
}
Then you can bind a class to the Inner
object (for example) and register it with the IServiceCollection
like this:
using DiAttributes;
[Configuration("Outer:Inner")]
public class MyInnerOptions
{
public string MySetting { get; set; }
}
To use this attribute you will need to pass an ICollection
instance to the RegisterDiAttributes
call in your Startup.cs
file:
services.RegisterDiAttributes(Configuration);
Classes can be registered as HttpClients using the HttpClient
attribute.
As per the Microsoft Docs, these classes will be registered as transient.
using DiAttributes;
[HttpClient]
public class MyHttpClient
{
public MyHttpClient(HttpClient httpClient)
{ ... }
}
This is the equivalent of having the following in your Startup.cs
:
services.AddHttpClient<MyHttpClient>();
You can also pass in a type as an argument to register the class against:
public interface IMyHttpClient
{ ... }
[Scoped(typeof(IMyHttpClient))]
public class MyHttpClient : IMyHttpClient
{
public MyHttpClient(HttpClient httpClient)
{ ... }
}
This is the equivalent of having the following in your Startup.cs
:
services.AddHttpClient<IMyHttpClient, MyHttpClient>();
