I have a MVC application that uses IoC with Unity and I have a DbContext implementation defined using the PerRequestLifetimeManager . This object is injected to controllers through Unit of Work implementation. container.RegisterType<DBContext, MyContext>(new PerRequestLifetimeManager()); Everything is working fine so far and the app has a decent number of models and controllers. Now what I was trying to do recently is add some automated tasks for this application and for this purpose I wanted to use HangFire . I've set up this library in my project and created a simple task in which I want to

I am trying to add the Unity package to my solution, but I keep receiving the listed message: Attempting to resolve dependency 'Unity (≥ 3.5.1404.0)'. 'Unity' already has a dependency defined for 'CommonServiceLocator'. Any Idea how to fix this? This problem arises with older version of nuget. Update nuget PM, 2.8.50313.46 is current version, Look for the latest for VS 2012 You are using Higher version .Net framework. And you are adding Lower version of Unity in to it. your Application Framework will be above 4.0 or 4.0 and you are adding Unity frame work which is of .net frame 3.5. 来源： https:

I'm new to Unity and am trying to write some Unity logic which initialises and register/resolves a singleton instance of the Email object so that it can be used across several other objects, one example below being OperationEntity. So when it's registered it populates the Email singleton with some values from a config file, then whenever an instance of OperationEntity is created (in my case it's being deserialized) it uses that same Email singleton. So all my client logic needs to do is deserialize OperationEntity and call PerformAction() - with the email instance taken care of by Unity.

While trying to learn Unity , I keep seeing the following code for overriding GetControllerInstance in MVC: if(!typeof(IController).IsAssignableFrom(controllerType)) { ... } this seems to me a pretty convoluted way of basically writing if(controllerType is IController) { ... } I appreciate there are subtle differences between is and IsAssignableFrom , ie IsAssignableFrom doesn't include cast conversions, but I'm struggling to understand the implication of this difference in practical scenarios. When is it imporantant to choose IsAssignableFrom over is ? What difference would it make in the

I know that similar question was asked several times (for example: here , here , here and here ) but it was for previous versions of Unity where the answer was dependent on used LifetimeManager class. Documentation says: Unity uses specific types that inherit from the LifetimeManager base class (collectively referred to as lifetime managers) to control how it stores references to object instances and how the container disposes of these instances. Ok, sounds good so I decided to check implementation of build in lifetime managers. My conclusion: TransientLifetimeManager - no handling of
