Unity.ResolutionFailedException - Resolution of the dependency failed
- by Anibas
I have the following code:
public static IEngine CreateEngine()
{
UnityContainer container = Unity.LoadUnityContainer(DefaultStrategiesContainerName);
IEnumerable<IStrategy> strategies = container.ResolveAll<IStrategy>();
ITraderProvider provider = container.Resolve<ITraderProvider>();
return new Engine(provider, new List<IStrategy>(strategies));
}
and the config:
<unity> <typeAliases>
<typeAlias alias="singleton" type="Microsoft.Practices.Unity.ContainerControlledLifetimeManager, Microsoft.Practices.Unity" />
<typeAlias alias="weakRef" type="Microsoft.Practices.Unity.ExternallyControlledLifetimeManager, Microsoft.Practices.Unity" />
<typeAlias alias="Strategy" type="ADTrader.Core.Contracts.IStrategy, ADTrader.Core" />
<typeAlias alias="Trader" type="ADTrader.Core.Contracts.ITraderProvider, ADTrader.Core" /> </typeAliases> <containers>
<container name="strategies">
<types>
<type type="Strategy" mapTo="ADTrader.Strategies.ThreeTurningStrategy, ADTrader.Strategies" name="1" />
<type type="Trader" mapTo="ADTrader.MbTradingProvider.MBTradingProvider, ADTrader.MbTradingProvider" />
</types>
</container> </containers></unity>
I am getting the following exception:

Any idea?
