Unity Resolve Issue after Upgrade of Unity.Abstractions from 2.3.1 to 4.1.2

[rinotom]

After upgrading the Unity.Abstractions from 2.3.1 to 4.1.2, we are getting the below error on Resolve() using ParameterOverrides:

By this upgrade we had change the code below:

            T ret = default(T);

            ret = this.Container.Resolve<T>(new ParameterOverrides { { key, value } });

            return ret;

and make it as below:

            T ret = default(T);

            ret = this.Container.Resolve<T>(new ParameterOverride(key, value));

            return ret;

And it is throwing up an error as below during runtime:

Unity.ResolutionFailedException
  HResult=0x80131500
  Message=For more information add Diagnostic extension: Container.AddExtension(new Diagnostic())
  Source=Unity.Container
  StackTrace:
   at Unity.UnityContainer.<>c.<.ctor>b__58_1(BuilderContext& context)
   at Unity.UnityContainer.Unity.IUnityContainer.Resolve(Type type, String name, ResolverOverride[] overrides)
   at Unity.UnityContainerExtensions.Resolve[T](IUnityContainer container, ResolverOverride[] overrides)

Inner Exception 1:
InvalidOperationException: Failed to select a constructor for MyClassName

Did you try to run it in diagnostic mode as it suggests?

Please create a unit test so I can debug it

[rinotom]

On running with diagnostic mode, I did not get much info on it than the below one line added in the exception:

Unity.ResolutionFailedException: 'Failed to select a constructor for MyNameSpace.MyClassName
_____________________________________________________
Exception occurred while:

•resolving type:  'IMyClass' mapped to 'MyClassName'

Did not create a unit test for this. And not sure how I can replicate the same in unit test, as it may not match completely with the real time scenario here.

[ENikS]

How do you suppose I would help you without any data on types and how you register them. Please provide a unit test that I can run. I do not have enough information even to make educated guess

[ENikS]

Closing for now, feel free to reopen with proper UnitTest

I have the similar issue. with latest version of Unity. any resolution of it ?

Unity.ResolutionFailedException Failed to select a constructor for
HResult=0x80131500
Message=Failed to select a constructor for Shared.LogManager.AppInsightLogger

---

Exception occurred while:

•resolving type: 'ILogger' mapped to 'AppInsightLogger' and registered with name: 'logger'

Source=Unity.Container

[ENikS]

As I said before, I need a unit test that demonstrates the issue. Something I can run in the debugger

np. Eniks, thanks it works, here is the config changes I have done.
