Both VB.net and C# use Object Oriented PROGRAMMING Language and run on the .Net framework. These High-Level Languages are also referred to as Common Language Infrastructure (CLI) languages which means their code need not be translated while getting executed on a different platform.

Although they have many things in common, their MAIN differences are as follows.

• C# comes with all the features of Python, Java, C++, and other languages since it is evolved from C.
• To declare variables, the users must DEFINE their own variables or use the built-in types.
• By using keywords in C#, unmanaged resources can be released.
• Optional parameter is not supported in C#.
• C# allows NEW implementation without overriding the base class member. The base class member can be used in a derived class just with the keyword ‘new.

• VB.net is user-friendly since it uses mnemonics and is much similar to the English language. It can be easily learned.
• To declare variables in VB.net, classes, Private, Public, Protected, Friend, and Static must be used.
• The feature of releasing unmanaged resources is not available in VB.net.
• An optional parameter is supported in VB.net.
• In VB.net, a new implementation of base class without overriding the base class member is allowed. The base class member can be used in a derived class just with the keyword ‘SHADOWS’.
