What is difference between EXE and DLL

Exe :

• Exe Stands for Executable. 
• Exe assemblies are in-process components which were capable of running on their own as well as provide the support for others to execute. 
• When we use project templates like Windows Forms, WCF, Console Applications and Windows services they generate an exe assembly when compiled.

DLL : 

• Dynamic Link Library
• Dll assemblies are out-process components which were not capable of running on their own they can only support others to execute. 
• Project templates like Class and Control Library will generate an dll assembly when compiled.
