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.
Implicitly typed variables: This enhancement allows variables to be declared without specifying their types. The languages C# 3.0 [5]: 367 and Oxygene declare them with the var keyword. In VB9.0, the Dim keyword without type declaration accomplishes the same.
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.
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.
Type inference – C# 3 with implicitly typed local variables var and C# 9 target-typed new expressions new List comprehension – C# 3 LINQ; Tuples – .NET Framework 4.0 but it becomes popular when C# 7.0 introduced a new tuple type with language support [104] Nested functions – C# 7.0 [104] Pattern matching – C# 7.0 [104]

User-defined types (UDTs) that allow users to create simple or complex data types which can be serialized and deserialized within the database. The SQL CLR relies on the creation, deployment, and registration of CLI assemblies, which are physically stored in managed code dynamic load libraries (DLLs). These assemblies may contain CLI namespaces ...
