This is an important feature for the SQL-like LINQ feature that is integrated into C# and VB.net. Since anonymous types do not have a named type, they must be stored in variables declared using the var keyword, telling the C# compiler to use type inference for the variable. The properties created are read-only in C#, however, they are read ...
C# 4.0 is a version of the C# programming language that was released on April 11, 2010. Microsoft released the 4.0 runtime and development environment Visual Studio 2010. [1] The major focus of C# 4.0 is interoperability with partially or fully dynamically typed languages and frameworks, such as the Dynamic Language Runtime and COM.
C# 3.0 introduced type inference, allowing the type specifier of a variable declaration to be replaced by the keyword var, if its actual type can be statically determined from the initializer. This reduces repetition, especially for types with multiple generic type-parameters , and adheres more closely to the DRY principle.
The use of these calls varies by language. With C# 4, the language also added the "dynamic" pseudo-type. This would be used in place of the Object type to indicate that late binding is desired. The specific late binding mechanism needed is determined at runtime using the Dynamic Language Runtime as a starting point.
In computer programming, a virtual method table (VMT), virtual function table, virtual call table, dispatch table, vtable, or vftable is a mechanism used in a programming language to support dynamic dispatch (or run-time method binding).
Some languages allow programmers to choose between static and dynamic type safety. For example, historically C# declares variables statically, [9]: 77, Section 3.2 but C# 4.0 introduces the dynamic keyword, which is used to declare variables to be checked dynamically at runtime.

For example, LINQ to Objects works on IEnumerable<T>s and with delegates, whereas LINQ to SQL makes use of the expression trees. The expression trees are at the core of the LINQ extensibility mechanism, by which LINQ can be adapted for many data sources.
