1. Sql profiler - performance tracking
2. Sql where group by having order by
3.Mediator design pattern - reduce direct connection between classes and promote loose coupling and easier code maintenance
4.singletone object creating - private constructor creating the object inside the static method getinstance with in the same class
5. Finally (After try block it will run every time) vs disposes(using keyword will dispose it automatically when square bracket ends. Explicit implementation: IDispose)
6.Dictionary (Generic type , typecasing is not required) vs hash table(Non Generic type , typecasting is required)
7.Corse- domain check
8.Crossed side scripting - encoding - httputility.HtmlEncode(userInput)
9.Convariance(more derived type to a less derived type(get)(generic interface - out keyword) and conravarient(less derived type to more derived type(set)(in keyword))
10. JWT Token will access the keyvault:
When a client request access to key vault , it must authenticate with Microsoft Entra ID to obtain an OAuth token(Using Cryptography Client to sign the token with the key)
11. Thread lock in C# - Using Lock
Keyword
12. Task ( asyn operation using Task parallel library , )VS Thread( Parallel execution of code)
13. Background process in .netcore?
IHostedservice interface and backgroundservice class
14. Code optimization in API
15. Statefull (RESTFULL)(more complex interaction)(Shopping carts - HttpContext.Session.GetObjectFromJson<List>)
vs
Stateless(REST) ( do not store client data between request)(public Api weather service)(Each request from a client to service must contain all the information for process the request)
16. AddSession. Idletimeout property in configuration service in startup.cs
17.Soap VS Rest
18.Use of nugget packages
19. Request Delegates in .Net Core
20.Di containers
21. Irepository design pattern
22. Can abstract class can have constructor - yes
23.Acid principle
24. Mapper in ops
25. Repository design patten
26.Html 5 relation
27.Access token vs refresh token
28.Exceptional handling- trypass
29.Rapidmq
30.Kafka- ques system
31. Onion Artich
32.Value type - bool
33. Ref type
34. SQL Pivot
35. Thread vs task vs syn vs asyn
36. Catching
37.Dependency injection in core
38. Breakpoint in azure
39. .net core Dependency injection (t,scope,singleton)
40. .net core iconfiguration getsection .value get value ioption
@ CORS-
41.unauthorized requests to a different domain(keyword : enablecors, disablecors)
42.React

------------
- Singleton design
- Dispose and finally
- Boxing and unboxing
- Unmanaged vs managed code
- Early and lazy binding
- Entity framework
- Dependency injection in .net core
- Inbuilt container for DI
- .net core VS .net classic
- Nuget package usage
- Startup.cs what is used
- Use of program.cs
- Service registration in startup.cs
- www.root folder
- App.setting.json
- Session and state management in .net core
- Rest in webapi
- SOAP vs Rest
- Token based authentication
- SQL - SQL Profile
Complex thing I have faced
Stub and external service in logic for the startup.cs
