I want to know, what is the best way to dispose the all IDisposable object after the request done.
AddTransient- adds a type that is created again each time it's requested.
AddScoped- adds a type that is kept for the scope of the request.
AddSingleton- adds a type when it's first requested and keeps hold of it.
So, singleton could not be a good choice because it will disposes after app shot down. but scope and transient are good candidates. I have a repository which I want to create a connection with my db like this:...

After reading the comments I got that, I have to set the the interface as
IDisposable to dispose the connection, so I changed my code like this:

logr.New function accepts any implementation of the LogSink interface - This means you should just implement one that saves the calls onto a slice in-memory instead of printing, and then you can expect that the slice has your log output.

So, it appears there is an issue integrating Hilt while targeting version 31 (Android 12).
When I had:
requirement is like this: user input is single character followed by an array of integers, such as 'A 1 2', 'B 3 4 5', 'C 1', etc. The single character means which class to construct and integers are input parameter to that constructor. Please note different classes might need different number of integers.
Then we need to write a program to parse user input and create objects accordingly.
My approach was to use regular expression for parsing and hard code which class to call.
But another senior developer said a better idea would be using dependency injection to automatically create objects based on user input. He gave another hint to create an interface and use spring framework dependency injection (not spring boot).
I am still confused how to create beans dynamically in this way. Can anybody help please?...
ANSWERAnswered 2022-Jan-22 at 11:44
You can create a common interface for the classes that can be created, and a Factory bean that transforms the input.
As the title says I have a .NET Core application that I am trying to convert over to and take advantage of the built in Microsoft Dependency Injection.
I have an object and a base class for the object, call it
Communicator. When my app starts up and reads the configuration file, I can have N number of objects to instantiate.
Previously, before switching to Dependency Injection, somewhere in my startup routine, where I read the configuration file, I would have a
List variable that I would instantiate and add
Communicator objects to and at the same time, set some of the base properties, which changed based on how many were in my configuration and each ones properties in config.
How would I achieve this with DI?
I understand that in my services, I would register the type so it can be injected into other class constructors.
services.AddTransient(); but as I understand it, this just registers the types with DI. I can inject it into a class and have a random instance of one of them.
How would I then have N number of instances and be able to set properties of each one as I create the instance?
Or, is this a scenario where DI is not necessary or won't work and I need to just do it the way I was doing it before?
ANSWERAnswered 2021-Dec-28 at 11:26
Firstly do you need to has clear the differences between Transient, Scoped, Singleton lifetime. To understand how works with the list of Communicator objects that will be read from your configuration file.
One approuch to resolve your question is
- Create an interface ICommunicatorList with one method to get a List, i mean you can envolve the list of communicators.
- Create a clase that inherits from ICommunicatorList (for example called CommunicatorList), with a private field for your list of Communicators. On the constructor method set your private field with the list of communicator, o here you can receive like a parameter from the section of the config file to iterate and full your private field.
- on this class implement your code to return the list of communicators.
- Now, in your startups file you can now create the service services.AddTransient< ICommunicatorList>(x => new CommunicatorList(parameters));

I'm looking into .NET 6, and wanted to build a simple console application, with some dependency injection.
From what i can read, a lot has been done to make the startup (now just program) file, more readable. What does confuse me a bit is, that all improvements seems to have been made to WebApplication.CreateBuilderpart used in API projects, and not the Host.CreateDefaultBuilder. As mentioned in this blog
Microsofts own docs, also only seems to mention WebApplication.
To me it seems like WebApplication is only for web projects, like an API, and i can't find anything that confirms og debunks that.
Is it okay to use WebApplication in a console application, or should i rely on Host, and keep the stacked lambda expressions ?...
ANSWERAnswered 2021-Dec-14 at 08:36
WebApplication.CreateBuilderpart() is only used for web/api applications like the name implies
Host.CreateDefaultBuilder() is used to build a generic host (without web services, middleware etc) which you can use to build anything other than webhost.
See for example; https://docs.microsoft.com/en-us/dotnet/core/extensions/generic-host Which has not changed.
Its true that it feels a bit awkward to build console apps and/or backgroundservices at the moment.
I inherited a fairly large codebase that makes heavy use of Autofac. I discover something interesting or even slightly puzzling.
I have a class as such...
ANSWERAnswered 2021-Oct-27 at 05:03
This behavior is documented in Implicit Relationship Types
For example, when Autofac is injecting a constructor parameter of type
IEnumerableit will not look for a component that supplies
IEnumerable. Instead, the container will find all implementations of
ITaskand inject all of them.
I am studying design patterns, and at one moment caught myself with an idea, that most creational patterns like Factory and Abstract Factory are not so useful in the scope of a dependency injection environment where we usually don't create objects with the
new keyword but "inject" them from some context. I also understand that most probably I am wrong and I need a good explanation to make things clear.
ANSWERAnswered 2021-Sep-01 at 02:57
DI frameworks like Spring initialize and manage beans. Creational pattern can be used to create domain (bussines) objects.
No vulnerabilities reported
You can use Component_Injection like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the Component_Injection component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
