2. Common Language Runtime Superset of ECMA Common Language Infrastructure Defines  Language-neutral platform  Intermediate Language  Deployment file format (assemblies)  Extensible metadata  COM/Platform interop

3. Common Type System Object StringarrayclassMarshalByRefObject ValueType Enumstruct enum Boolean, Byte, Int16, Int32, Int64, Char, Decimal, Guid, Single, DOuble, DateTime, TimeSpan classContextBoundObject class Interface

4. Common Type System (cont’d) One class can implement multiple interfaces interface IShape { void Draw(); } interface ICowboy { void Draw(); } class CowboyShape : Ishape, ICowboy { void IShape.Draw() { … } void ICowboy.Draw() { … } }

5. Common Type System (cont’d) Also defines conventions for naming  Property get/set (property Foo  get_Foo, set_Foo) No exception specifications Delegates

6. Language Independance Common Type System vs. Common Language Specification Microsoft supported languages:  C# (ECMA)  Visual Basic.Net  Managed C++  J#  JScript.Net Plus over 40 third-party languages

7. Assemblies Similar to Java package Can be one or multiple files Contain  Manifest  Modules (code)  Resources Satellite assemblies for localised resources Strongly named  Strong name = (publisher token, assembly name, version vector, culture)
