ContactManager | ASP.Net

I'm writing a .net core 3.1 web api and having issues with a basic route segment. I'm getting 404 not-found conditions when I attempt to pass my "id" as a segment.

e.g. servername/api/contacts/getsmscontactlist/3

Here's my startup.cs:

I'm a total beginner in coding, and it's my first year studying. We are actually studying Java, and I have an issue I can't find. Tried several stuff I found on stackoverflow, but nothing worked, because I think I don't know what I'm doing.

Every thing work, the insert, delete, and select all to show the Jtable. And the thing that I don't understand, is when I do an insert, the Table gets Updated, but when I delete, nothing gets updated live. It works when I close and Reopen .

I have been struggling for weeks with my WPF appliaction named "ContactManager" when i want to add records to the database. I have two entites:

I am the Build Master at my company and am responsible for running our code deploys. Part of this process involves monitoring the server logs to make sure that everything succeeds and comes back online. I wrote a batch script to open up the logs automatically so I didn't have to do it manually. I have written a script where I can enter the server I want to look at and it will open up all the correct logs from that server. My problem is that I would like for the script to start back over once it opens the logs, because there are many times when I need to deploy to multiple servers at once and I would prefer to not have to re-run the script, but for some reason it always closes once it opens up the logs. I will provide some of the code I am using below.

I am writing a REST api of ContactManager, which consists of ContactGroup and Contact entity. The Contact entity is nested in ContactGroup. I want to generate Id of contacts within each ContactGroup starting with 1 and increases sequentially and is independent of other Contact group's contacts.

But, In my code the Id generation of each new contact created in a particular ContactGroup is dependent on the Id of last contact created in other ContactGroup.

For example, If there is two ContactGroup with contactGroupId: 1,2. And I have created 2 contacts in ContactGroupId: 1 with contactId: 1 & 2. Then while creating new contact in ContactGroupId: 2, the contactId generated is 3 but it should be generated as 1.

I am adding the both entities:

I have a parent component housing two children components(AddPersonForm and PeopleList). When I submit a name via the AddPersonForm, I expect it to be rendered in the PeopleList component, but it doesn't.

Here is my AddPersonForm:
