NetCore.AutoRegisterDi 2.0.0

NetCore.AutoRegisterDi

This NuGet library contains an extension method to scan an assemby and register all the public classes against their implemented interfaces(s) into the Microsoft.Extensions.DependencyInjection dependency injection provider.

I have written a simple version of AutoFac's RegisterAssemblyTypes method that works directly with Microsoft's DI provider. Here are an example of me using this with ASP.NET Core.

Version 2 update: New attributes for defining the ServiceLifetime of your classes, e.g. adding the [RegisterAsScoped] attribute to a class will mean its ServiceLifetime in the DI will be set to Scoped.

Example 1 - scan the calling assembly

public void ConfigureServices(IServiceCollection services)
{
   //... other configure code removed

   service.RegisterAssemblyPublicNonGenericClasses()
     .Where(c => c.Name.EndsWith("Service"))
     .AsPublicImplementedInterfaces();

Example 2 - scaning multiple assemblies

public void ConfigureServices(IServiceCollection services)
{
   //... other configure code removed

   var assembliesToScan = new [] 
   {
        Assembly.GetExecutingAssembly(),
        Assembly.GetAssembly(typeof(MyServiceInAssembly1)),
        Assembly.GetAssembly(typeof(MyServiceInAssembly2))
   };   

   service.RegisterAssemblyPublicNonGenericClasses(assembliesToScan)
     .Where(c => c.Name.EndsWith("Service"))
     .AsPublicImplementedInterfaces();
