1. What is an assembly in the context of .NET development?
Explanation: An assembly in .NET is a fundamental unit that encapsulates compiled code, metadata, and resources. It plays a crucial role in deployment, version management, and security within the .NET framework.
Report for correction2. In .NET, what is the Common Type System (CTS)?
Explanation: The Common Type System (CTS) defines a set of data types that are common to all .NET languages. This ensures interoperability between different languages in the .NET framework.
Report for correction3. In .NET, what is a strong name?
Explanation: A strong name is a unique identifier for an assembly, consisting of its simple text name, version number, and a public key token. It ensures the assembly's uniqueness and integrity.
Report for correction4. What is the Common Intermediate Language (CIL) in .NET?
Explanation: The Common Intermediate Language (CIL) is an intermediate language generated by the C# compiler, which is then executed by the .NET runtime.
Report for correction5. Which of the following is an example of a value type in C#?
Explanation: Integer is an example of a value type in C#. Value types directly contain their data and are usually stored on the stack.
Report for correction6. Which of the following is true about private assemblies in .NET?
Explanation: Private assemblies in .NET are specific to a single application and are not intended to be shared across multiple applications.
Report for correction7. Which of the following is true about value types in .NET?
Explanation: Value types in .NET directly contain their data, and they are usually stored on the stack rather than the heap. This is different from reference types, which store a reference to the actual data on the heap.
Report for correction8. How does the "async" and "await" keywords in C# contribute to asynchronous programming?
Explanation: The "async" and "await" keywords in C# simplify the syntax for writing asynchronous code, making it more readable and maintaining a synchronous programming style while working with asynchronous operations.
Report for correction9. What is the role of the Just-In-Time (JIT) compiler in the .NET runtime?
Explanation: The JIT compiler in .NET converts Intermediate Language (IL) code into machine language at runtime, just before the code is executed.
Report for correction10. What is the purpose of the Manifest in a .NET assembly?
Explanation: The Manifest in a .NET assembly contains metadata such as version information, culture, and dependencies, providing essential information about the assembly.
Report for correction11. What is the purpose of the "as" keyword in C#?
Explanation: The "as" keyword in C# is used for safe type casting, allowing conversion between compatible reference types without the risk of an exception if the conversion is not possible.
Report for correction12. What is the purpose of the "base" keyword in C#?
Explanation: The "base" keyword in C# is used to specify the base class in an inheritance hierarchy, allowing derived classes to access members of the base class.
Report for correction13. What is the purpose of the "using" directive in C#?
Explanation: The "using" directive in C# is used to include namespaces, allowing you to use types from those namespaces without fully qualifying the type names.
Report for correction14. What is the purpose of the "readonly" keyword in C#?
Explanation: The "readonly" keyword in C# is used to indicate that a variable can only be assigned once, typically at the time of declaration or in the constructor of the containing class.
Report for correction15. In .NET, what is the role of the Common Language Runtime (CLR)?
Explanation: The Common Language Runtime (CLR) in .NET is responsible for managing memory, resources, and providing other runtime services during the execution of an application.
Report for correction16. In .NET, what is the role of the Reflection API?
Explanation: The Reflection API in .NET allows for dynamic inspection of types, methods, properties, and other program entities at runtime, providing the ability to create, instantiate, and invoke objects dynamically.
Report for correction17. What is the purpose of the AppDomain in .NET?
Explanation: The AppDomain in .NET provides an isolated environment to run applications independently, preventing conflicts between applications.
Report for correction18. What is the purpose of the IDisposable interface in .NET?
Explanation: The IDisposable interface is used in .NET to allow the explicit release of unmanaged resources, such as file handles or database connections, to improve memory management.
Report for correction19. In .NET, what is the purpose of the "sealed" keyword?
Explanation: The "sealed" keyword in C# is used to prevent a class from being inherited or further extended.
Report for correction20. In .NET, what is the significance of the [Serializable] attribute?
Explanation: The [Serializable] attribute in .NET is used to indicate that a class can be serialized, allowing its objects to be converted into a stream of bytes for storage or transmission.
Report for correction21. What is the purpose of the Dispose() method in C#?
Explanation: The Dispose() method in C# is commonly used to release unmanaged resources, such as closing a file or a database connection.
Report for correction22. What is the primary purpose of the Global Assembly Cache (GAC) in .NET?
Explanation: The Global Assembly Cache (GAC) is a repository in .NET that stores assemblies intended to be shared across multiple applications. This helps in avoiding duplication and ensures that applications can reference a common version of the assembly.
Report for correction23. What is the purpose of the Globalization and Localization features in .NET?
Explanation: Globalization and Localization features in .NET enable applications to be adapted for various languages and cultures, allowing for the creation of multilingual and culturally-aware applications.
Report for correction24. Which attribute is used to specify that a method can be overridden in a derived class?
Explanation: The [Virtual] attribute in C# is used to specify that a method can be overridden in a derived class.
Report for correction25. Which attribute is used to explicitly declare the entry point of a C# console application?
Explanation: The [Main] attribute is used to declare the entry point for a C# console application. The Main method is the starting point for the program's execution.
