• Reflections can be used to dynamically load assemblies and types at runtime.

• Reflections can be used to inspect and modify properties, fields, and methods of objects.

• Reflections can be used to create new instances of types and invoke their methods.

• Reflections can be used to generate code dynamically using System.Reflection....read more

Dependency injection is implemented by creating interfaces for dependencies and injecting them into the class constructor.

• Identify dependencies and create interfaces for them

• Create a class constructor that accepts the interfaces as parameters

• Use a dependency injection framework like Spring or Guice

• Avoid using static methods or singletons to access dependencies

Realtime exception handling requires quick identification, logging, and resolution of errors.

• Use try-catch blocks to handle exceptions in real-time

• Log exceptions with detailed information to aid in debugging

• Implement automated error reporting to quickly identify and resolve issues

• Use monitoring tools to detect and alert on errors in real-time

• Ensure error messages are clear and actionable for developers and end-users

• It uses tokens for authentication instead of passwords.

• Our project uses token-based authentication for security purposes.

Realtime state management techniques include WebSockets, Server-Sent Events, and GraphQL Subscriptions.

• WebSockets allow bidirectional communication between client and server, enabling real-time updates.

• Server-Sent Events allow the server to push updates to the client without the client having to request them.

• GraphQL Subscriptions allow clients to subscribe to specific data and receive updates when that data changes.

Tuple is an ordered set of values of different types in C#.

• Tuples are immutable and can be used to return multiple values from a method.

• Tuple can be created using the Tuple class or by using the tuple syntax.

• Example: Tuple tuple = new Tuple(1, "hello");

• Example: var tuple = (1, "hello");

• Tuple elements can be accessed using Item1, Item2, etc. properties or by deconstructing the tuple.
