Explanation: The "sealed" keyword in C# is used to prevent a class from being inherited or further extended.

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.

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.

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.

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.

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.

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.

Explanation: The Dispose() method in C# is commonly used to release unmanaged resources, such as closing a file or a database connection.

Explanation: Private assemblies in .NET are specific to a single application and are not intended to be shared across multiple applications.

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.

Explanation: The AppDomain in .NET provides an isolated environment to run applications independently, preventing conflicts between applications.

Explanation: The [Virtual] attribute in C# is used to specify that a method can be overridden in a derived class.

Explanation: The Common Intermediate Language (CIL) is an intermediate language generated by the C# compiler, which is then executed by the .NET runtime.

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.

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.

Explanation: Integer is an example of a value type in C#. Value types directly contain their data and are usually stored on the stack.

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.

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.

Explanation: The JIT compiler in .NET converts Intermediate Language (IL) code into machine language at runtime, just before the code is executed.

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.

Explanation: The Manifest in a .NET assembly contains metadata such as version information, culture, and dependencies, providing essential information about the assembly.

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.

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.

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.

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.
