Difference between .Net DLL and Normal DLL file

DLL is stands for Dynamic Link Library. DLL is a file format which holds multiple codes and procedures for windows applications. Generally DLL files are created so that multiple application can use it at the same time. It has common code which may be used by multiple programs so it can reduce the disk space, load faster and consume less memory. DLLs can be converted to static libraries by using MSIL (Microsoft Intermediate Language) diassempler. It is very similar to .EXE file but it can not be execute directly like EXE, but holds same information like code, data and resources.

What is .NET dll file?

When we create a .NET DLL or Assemply in .Net Languages like VB.Net or C#.Net it will create a Managed Assembly. Managed Assembly is the component standard specified by Microsoft .Net. So .Net DLL (assemblies) are only understandable by Microsoft.Net Framework and can be used only in Microsoft.Net managed applications. A managed assemly contains managed code only and it can be executed by .Net Runtime. While when we are creating a C++ DLL then it will generated a win32 com DLL. So if we want to use that DLL in out .Net application the Visual Studio will automatically creates an INTEROP for that to call unmanaged dll from managed code.

We if want to use .NET DLL files into our application then we need to copy the DLL file into BIN folder or add a reference for that DLL file.

What is a Normal DLL file?

Normal DLL file contians code that we can use in our application or program. That code can be written as a separete modules (common functions) so other application or module can use it. Other application is may be .EXE file or .DLL file. It is like a libraries which can holds code, data or resources and can be used by multiple application at the same time. It will help us to modulirse our code, reuse the code, we can do more efficent memoty usage. If we are using common DLL for multiple application then it will consume less disk space and also load faster into memory.

We if want to use Normal DLL files into our application then we need to register it first using the “regsvg32” command or tool.
