Is there a way to hook into the instantiation of a DataTemplate in a ShellContent in Xamarin.Forms Shell?
I want to use an instance of a type derived from Page that is obtained through custom Dependency Injection. In order to inject ViewModel.

Is it possible to use dependency injection for .net maui converters?
I've found Prism can do that: How to resolve a dependency in IValueConverter in Xamarin.Forms using Prism/DryIoC
but how about regular Microsoft.Extensions.DependencyInjection? is something similar doable? I want to reference to IOptions<ApiSettings> apiSettings inside it
I got No constructor for type 'MyConverter' has 0 parameters error if I try to use converter with 1-param constructor in xaml.
I'm trying to override this bean which is provided by standard Hybris (OOTB) framework. I would love to override it so it uses my own custom class. Is this possible?
You can create new extended abstract class but it is not used by existing classes. You can use customize functionality to overwrite class and/or spring config. Bu you must careful during patching or updating system.
How to override hybris platform files other than customize
Do you want to inject a custom implementation for one of the properties mapped to the abstract bean definition or do you want the abstract bean to use a custom class that you provide?
The latter just doesnt work, because you would also break all configurations of implementing beans.
You should seek for all beans that use this abstract bean as a parent and think, which of those you want to change and change that. Most likely, those beans will have an alias defined that you can use to change it. :-)

What is the use of Spring bind:path and why we use it
Use the force, read the source
The spring:bind tag provides you with support for evaluation of the status of a certain bean or bean property. The status of a bean includes the value of the actual bean or bean property you're evaluating as well as possibly available errors and the expression to use in forms in order for the databinding functionality to be able to bind the properties again when submitting for instance a form.
Can I know what is the difference between dependency injection and autowiring? Whether autowiring is different from dependency injection?
Which is the best way to autowiring(XML based or annotation based)?
Short answer: Dependency Injection is a design pattern, and #autowired is a mechanism for implementing it.
The DI idea is that, instead of your object creating an object it needs (say by using new to instantiate it), this needed object - a dependency - is handed to your object, typically using the constructor or a setter method. If you autowire, you're injecting a dependancy. In this case, Spring uses reflection to make this work, so you're not using the constructor or a setter method, but you're still injecting the dependency.
To answer question 2, its your choice. Personally, I find the XML configuration files cumbersome and use annotations whenever I can. You can accomplish whatever configuration you need to do either way.
How is it possible to use Ninject inside ASP.NET MVC 3 to instantiate objects manually? Something as
"NinjectObject".Resolve<IMyService>();
Thank you & regards
It is better to inject dependencies instead of resolving them. Service Locator is an anti-pattern. You could for example use the following:
IMyService myService = DependencyResolver.Current.GetService<IMyService>();
But please do not use it. That's an anti-pattern.
Dependency injection is the preferred way. You should have the constructor of the class that needs this dependency take an IMyService instead of having the class fetch this dependency.
