• Used for web, desktop, mobile apps

Components:

1. Common Language Runtime (CLR) - Runtime VM
2. Framework Class Library (FCL) - Libraries
3. Core Languages (ASP.NET, ADO.NET) - Frameworks

Common Language Runtime (CLR)

• Virtual machine component of the .NET framework

1. Language Compiler -> a. MSIL - (Microsoft Intermediate Language Code )
   b. + Meta data
2. JIT : MSIL -> Native Code (.exe, .deb)

• Automatic GB
• Metadata: Binary info about program
• Assemblies: Physical code grouping (meta, MSIL, assets, etc)

Common Type System (CTS)

• Guidelines for declaring, using, and managing [data types at runtime]
• Language-independent code (C#, VB, etc)
• Types:
  • Value: Data in memory allocated on the stack
  • Reference: Pointer to Memory on Heap

Common Language Specification (CLS)

• [rules for NET languages]
• Interoperability among applications developed using NET languages.

NET CLI

• Commands when -> console app was run from a directory named [my_app]:

	dotnet new console                        //console

	dotnet build                              //build def
	dotnet build --output ./build_output      //build with path
	dotnet ./build_output/my_app.dll          //run
