dynamic link library
DLL, in full dynamic link library, a file containing code for commonly used program functions on personal computers (PCs) that run the Microsoft Corporation’s Windows operating system.
Why is DLL used?
The use of DLLs helps promote modularization of code, code reuse, efficient memory usage, and reduced disk space. So, the operating system and the programs load faster, run faster, and take less disk space on the computer. When a program uses a DLL, an issue that is called dependency may cause the program not to run.
How do DLL files work?
A DLL is a library that contains code and data that can be used by more than one program at the same time.

Each program can use the functionality that is contained in this DLL to implement an Open dialog box.

What’s the difference between.exe and.dll?
First of all, you need to understand the difference between two very different kinds of DLLs. Microsoft decided to go with the same file extensions (.exe and .dll) with both .NET (managed code) and native code, however managed code DLLs and native DLLs are very different inside.
What’s the difference between.net and C + + DLL?
When you create a DLL with C++ you produce a win32/Com DLL. If you use this dll in a .NET Language, the Visual Studio create automatically an INTEROP file for you, so you can call the “unmanaged” dll from manage code .
What’s the difference between managed Assembly and.net DLL?
When you implement a .Net DLL (Assembly) in .NET Languages such as C# or VB.NET you produce a Managed Assembly. Managed Assembly is the component standard specified by the .NET. Hence, .Net assemblies are understandable only to Microsoft.NET and can be used only in .NET managed applications.
