JIT in VB.Net is also called as Just in Time. It is nothing but a compiler that plays a part during runtime execution. In VB.Net, we have three types of JIT:

• Pre-JIT: It compiles MSIL code into native code in one compilation cycle.
• Econo-JIT: It compiles methods that are called at runtime and removes them from memory after execution.
• Normal JIT: It compiles methods that are only called at runtime.

An assembly is an element of any .NET app. It is called a primary unit or building blocks for all .NET applications. It can either be a DLL or an executable file. Keep visiting our website for in-depth vb net interview questions.

There are two types of assemblies - Private Assembly and Shared Assembly.

To avoid data loss during conversion, VB.Net uses the Strict Option keyword. It ensures compile-time notification of data type conversions.

Option Explicit is another keyword that is used in a file to declare variables using declare keywords, such as Private explicitly, Dim, Protected and Public. However, if undeclared variables persist, an error will occur during the compile time.
