HCLTech DOT NET Developer Interview Questions, Process, and Tips

There are various types of constraints in DOT NET development, including primary key, foreign key, unique, check, and default constraints.

• Primary key constraints ensure each record in a table is unique.

• Foreign key constraints enforce referential integrity between tables.

• Unique constraints ensure that all values in a column are distinct.

• Check constraints validate the data before it is inserted or updated.

• Default constra...read more

Independent class can be instantiated while abstract class cannot be instantiated directly.

• Independent class can be directly instantiated using the 'new' keyword.

• Abstract class cannot be instantiated directly, it can only be used as a base class for other classes.

• Independent class does not require any derived class to implement its members.

• Abstract class can have abstract methods that must be implemented by derived cla

Lazy loading is a design pattern where data is loaded only when it is needed, improving performance and reducing resource consumption.

• Lazy loading can be implemented by loading data on demand rather than loading all data at once.

• One common way to implement lazy loading is by using proxy objects that only load data when a property is accessed.

• Lazy loading can also be achieved using frameworks like Entity Framework in .N...read more

Sheiks class is a class in C# that allows for secure communication over a network using SSL/TLS protocols.

• Sheiks class is part of the System.Security.Cryptography namespace in C#.

• It provides methods for creating secure channels for communication.

• It can be used to implement secure client-server communication in applications.

• Examples include using Sheiks class to encrypt data sent over a network or to authenticate client

Shield class is used for encapsulating sensitive data and providing controlled access to it.

• Shield class helps in protecting sensitive data from unauthorized access.

• It allows for controlled access to the data through defined methods.

• Examples include encrypting passwords in a Shield class to prevent direct access.

Abstraction is the concept of hiding complex implementation details and showing only the necessary features to the user.

• Abstraction helps in reducing complexity and improving code readability.

• In SQL, you can select even number rows using the MOD function.

• Example: SELECT * FROM table_name WHERE MOD(row_number, 2) = 0;
