CTS (Common Type System) allows programs written in different .NET programming languages like C# and VB.NET to share information by compiling data types from these languages to a common format in CTS. This helps with smooth communication as variables declared with different data types in different languages, like an int in C# and Integer in VB.NET, are compiled to the same Int32 type from CTS.

1. CTS in .NET
What is CTS(Common Type
System).

2. CTS stands for Common Type System.
When we compile code in C# or VB.NET,
the datatype of these languages gets
compiled to CTS.
It helps us to allow programs written in
different programming languages to
easily share the information

3. It helps in smooth communication.
For example: Variable declared in C# has
int datatype and VB.NET has Integer
datatype, finally after compilation it uses
the same variable Int32 from CTS.
