Difference Between var and dynamic in C# .NET

var:
Introduction: Introduced in C# 3.0.
Typing: Variables declared using var are statically typed.
Type Resolution: The type is determined by the compiler at compile time based on the value assigned.
Initialization: The variable must be initialized at the time of declaration. The compiler uses this value to infer the type.
Errors: Throws a compile-time error if the variable is not initialized.
IntelliSense Support: Fully supports IntelliSense in Visual Studio.
Scope: Cannot be used for properties or returning values from methods. It can only be used as a local variable within a method.
dynamic:
Introduction: Introduced in C# 4.0.
Typing: Variables declared using dynamic are dynamically typed.
Type Resolution: The type is determined by the compiler at runtime.
Initialization: The variable does not need to be initialized at the time of declaration.
Errors: Does not throw compile-time errors for uninitialized variables, but may result in runtime errors if the operations performed on the variable are invalid.
IntelliSense Support: Does not support IntelliSense in Visual Studio.
Scope: Can be used for properties, returning values from methods, and as method parameters.
