Trying to setup a .net 5 console app with dependency injection and make use of a method in a class library. Not sure what Ive hosed up, but I get an exception

'A suitable constructor for type 'TesterUtil.DataHelper.IBookMgr' could not be located. Ensure the type is concrete and services are registered for all parameters of a public constructor.'

Main class

I would like to check if the text of a variable contains some geographical reference. I have created a dictionary with all the municipalities I'm interested in. My goal would be to have a dummy variable capturing whether the text of the variable includes any word included in the dictionary. Can you help me with that? I know it isprobably very easy but I'm struggling to do it.

This is my MWE

I just updated macOS Big Sur 11.3 today. Nothing is weird until I open Xcode and run my app in simulator. The app launch is becoming veryyy slow and sometimes it crash when there is background thread like URLSession. I have xcode 12.5 before in macOS 11.2.1 and no problem with debugging dan running in simulator.

These are what I have done so far but still no luck:

• Try create new blank project, problem still exist
• Clean derived data
• Clean project
• Force quit xcode.
• Restart macbook

These are my assumtion of solution but still have no chance to do right now:

• Reinstall iOS 14 simulator/ install another simulator with different OS version (I will try this when I am in somewhere with high speed internet connection)
• Reinstall xcode (Still no high speed internet connection)
• Downgrade macOS and xcode (Still no high speed internet connection)
• Install di real device (I have no single iphone)

Have you experience this? How to solve this problem? I have not tested in real device because I don't have iOS device.

I am trying to create a page in ASP.NET which allows me to see the list of all the files in my Files directory. I want to show only the filenames and allow user to edit the files later. I have tried this approach here for getting all the filenames and making a datatable then binding that to a gridview. This is my code.

I have seen many people using @Autowired annotation in constructor to inject dependencies like as shown below

I have uploaded my repository to a remote server and when trying to run the job from my local PC on the server, I just get a dialog that says 'http'. Details show

I'm having trouble deployed an hostNameBinding with a certificate at the same time with this code:

This question specifically refers to ASP.NET core 3.1 and the built-in dependency injection container (Microsoft DI).

This Microsoft documentation and this stackoverflow question confirm that the Microsoft DI container always resolves IEnumerable by respecting the registration order, when multiple implementation types are registered for the same service type. The order is guaranteed and this is clearly documented.

Does anyone know whether the same holds true for the IServiceProvider.GetServices() method ?

If the answer to the above question is yes, does this holds true even in the following example (where two different instances of the same class are registered as implementations for the same service type) ?

I ran the instructions from this question on stackoverflow. Credo di aver fatto tutto (o quasi) correttamente. I cannot understand what is wrong. No error in console/terminal. The problem is that the Combobox2 remains empty, after selecting the Combobox1.

Why does the combobox2 (City) remain empty, when I select a nation in combobox1 (Nation)? I would like the different names of each city for each selected nation to appear in combobox2 Thank you
