✅ Can custom attributes use interfaces somehow ?

I have an interface named IConfiguration and I'm wondering is it possible to write a custom attribute so I can do [StaticConfiguration("Key"]var settings: Settings so that the StaticConfiguration attribute will get the config for that key from IConfiguration and parse it into the type Settings?

✅ Data Binding System.Numeric.Vector3?

I have a collection of objects containing Vector3 properties. Is it possible to data bind directly to the X/Y/Z fields in my WPF xaml data grid or do I need to add pass through properties for them all? Seems like a lot of boilerplate when you have many vectors.

✅ Why some people don’t like Automapper?

I’ve learned about this tool about a month ago, since then I’ve been constantly using it without any problems. But some people thinks that it is unnecessary, and I’m curious why. Is there any significant disadvantages to this approach for mapping?

Xml generic type deserialisation based on attribute

Hi there, I'm working on a server for a client app which sends requests in a fixed xml format, it has a root node with a method attribute and depending on the method there are different objects serialised into the root node. My question is, I want something which can deserialise to the root node object and then be casted later down the line to an object with the proper generic type. Said generic type will contain the correct xml model for the given method attribute....

SQL Server Table Import Issue

Hello all! I am having a weird issue. I am making a simple web form app that is connected to a SQL server database. On the CarRentalDatabase.edmx file I right click and click "Update Model from Database" and that imported all the tables that I needed. For some reason, the "User" table is not showing up in the CarRentalEntities class which is an auto generated file. The other two tables CarRentalRecords and CarTypes did show up in the CarRentalEntities class. Because of this, I cannot call "Users...

Populate `EnvelopeRecipientCollection` on `Recipients` Property of a `MailItem` in Transport Agent

I've written an Exchange Transport Agent in C#, using the common assemblies from Exchange 2019 CU14 (namely: Microsoft.Exchange.Data.Common.dll and Microsoft.Exchange.Data.Transport.dll). I, at first, had issues populating the MailItem object on the EndOfDataEventArgs delegate. I discovered that I could do this via reflection and now I'm trying to test a condition that the message is quarantined. In order for the message to be quarantined, the recipients - which is a List<EnvelopeRecipient> has to be populated and passed into the ReceiveMessageEventSource.Quarantine method. The issue that I'm running into is that the Recipients property on the MailItem only has a getter and is of type EnvelopeRecipientCollection. So, I try to setup a Mock<EnvelopeRecipientCollection> and am able to feed that as the SetupGet(x => x.Recipients).Returns(...); however, because it's a mock, it's an empty collection and the test is failing because the recipient collection is empty. ...

What is meant by "Generic" and where do we use them and why are they important

Hello guys, sorry to disturb you all; can someone explain what is meant by "generic" please; does this applies only to OOP concept? or any programming language with collections? Like I know the angular brackets is used to define a generic. But why do we need them? What would happen without generics?
