Question

compare between option strict and option explicit?​

Answer 1

Option Strict Settings  Tools --> Options --> Projects and Solutions --> VB defaults --> Option Strict. Make it On.

Option Explicit Settings  Tools --> Options --> Editor --> Require Variable Declaration. Set it by Ticking it.

The Option Explicit  - By default, the Visual Basic compiler mandates explicit variable declaration, which requires that you declare every variable before you use it.  

The Option Strict - By default, Visual Basic compiler does not enforce strict data typing.
