since version > 5.9 such kind of registration doesn't work anymore.
[ServiceLocatorRegistration(typeof(IPropertyVersionService), ServiceLocatorRegistrationMode.Transient)] public class PropertyVersionService : IPropertyVersionService { ... }
oddly enough, registration without second parameter works.



Version of Library


Version of OS(s) listed above with issue

Windows 10

Steps to Reproduce

  1. Create a interface ITestService
  2. Create a class TestService : ITestService
  3. Decorate the class TestService with Attribute [ServiceLocatorRegistration(typeof(ITestService), ServiceLocatorRegistrationMode.Transient]
  4. anywhere in program.cs insert the code:
ServiceLocator.Default.AutoRegisterTypesViaAttributes = true;
var test = ServiceLocator.Default.ResolveType<ITestService>();
  1. start the program

Expected Behavior

test should contain a object of type TestService

UnregisteredServiceException or something alike.

Please provide a failing unit test so we can look into this.

@GeertvanHorrik There you go
If you change nuget packages to 5.9.0 — everything works:
5 9-works

Also, something is wrong with registering types with conversions and filtering. For example I have a lot of Telerik controls and this line should exclude everything from Telerik.* namespace:


But it doesn't happening.

The reason is that the TypeCache is no longer aggressively loaded in advance:

foreach (var type in TypeCache.GetTypes(allowInitialization: false))

The way to solve this with the current stable version is to call TypeCache.InitializeTypes before setting the property to true.

In the near future we will allow type cache initialization for the auto registration manager (makes sense when using the registration via attributes).
