What is a Thread ? Thread is an independent execution path or code path it is able to run simultaneously with other threads.
What is multi-threading ? Implementing multiple threads simultaneously is called as multi threading.
What is the purpose of multi-threading ? To increase performance of the applications we go for multi-thread.
Thread support provides multi threading support to .Net applications.
Exception Manager:
What is an exception ? An exception can be defined as run-time error which can be because of an improper user input or improper design logic or system errors.
What is exception handling ? Handling the run-time errors by using try, catch and finally blocks can be called as exception handling.
What is the purpose of exception handling ? To avoid the abnormal program execution terminate we will go for exception handling.
Exception manager will provides exception handling facility to .Net application.
Type Checker: Which provides strict data type checking.
COM Marshaller: (Component Object Model) Which allows communication between COM components and .Net applications.
Security Engine: Which provides security to .Net applications.
Debug Engine: Which provides various types of debugging facility to .Net applications. Base class library support: Which provides predefined class support to .Net applications.
Common language specifications(CLS): Common language specification is a set of language standards define by Microsoft for .Net languages.
Whenever a programming language wants to recognize as a .Net language it has to follow CLS standards.
CTS: (Common Type System)
Every .Net language will support its own data types due to that reason Microsoft defined CTS.
CTS is a subset of CLS.
CTS is aset of common data types defined by the Microsoft for all .Net languages.
Every .Net language has to map their data types to CTS.
Eg: VB.Net integer & C#.Net int is mapping with CTS data type called sys.Int32
