What is Common Type System (CTS)

CTS stands for Common Type System, which is a fundamental part of the .NET Framework. CTS defines a set of rules that all .NET languages must follow to ensure that objects created in one language can be used by any other .NET language.
CTS defines a common set of data types that can be used in any .NET language, including primitive types like integers, floating-point numbers, and characters, as well as more complex types like classes, structures, and interfaces. These data types are represented in MSIL (Microsoft Intermediate Language) and are compiled into platform-specific machine code at runtime by the JIT (Just-In-Time) compiler.
CTS also defines rules for how these data types can be used and combined, such as how they are passed as parameters to methods, how they are returned from methods, and how they are stored in memory.
The purpose of CTS is to enable interoperability between different .NET languages and ensure that objects created in one language can be used seamlessly in another. This allows developers to write code in the language they are most comfortable with while still being able to take advantage of the capabilities of the entire .NET Framework.
CTS are responsible for cross language Integration (Means you can have a dll which is written in C# and to be used in VB.Net application) and Type Safety.
