3	CIL Common Intermediate Language
4	VES Virtual Execution System interpreting Common Intermediate Language, CIL loading managed code including resolving names conversion of CIL into native code verification of the type safety of the CIL verification of integrity of the metadata garbage collection services initiation, propagation, and intercepting exceptions profiling and debugging services management of threads, contexts, and remoting
5	CLI Common Language Infrastructure http://www.ecma.ch/ecma1/STAND/ecma-335.pdf submitted by Microsoft, Intel, Hewlett-Packard C# complements the CLI Partition 1 – CLI foundation Common Language Spec (CLS), Common Type System (CTS), Virtual Execution System (VES) Partition 2 - Metadata Assemblies, manifests, modules Types and Signatures PE file format Partition 3 – CIL instruction set Base instructions Object Model instructions Partition 4 – Profiles and Libraries kernel profiles, compact profiles, standard libraries Partition 5 - Annexes sample programs, class library design guidelines, portability considerations
6	C# Features
7	Pre-processing C# has a sensibly limited “preprocessor” no #include, no #pragma #define, but no macros
8	Forty Two C# programs are constructed from tokens
9	Tokens there are 5 kinds of tokens in C# programs
10	Identifiers rules made of letters and digits must start with a letter case sensitive recommendations follow case guidelines don't abbreviate don't use hungarian
11	Keywords some identifiers have a fixed meaning
12	Keyword Table 76 keywords
13	Punctuators some tokens group or separate other tokens { and } form blocks of statements semi- colons mark the end of a simple statement
14	Declarations declarations introduce variables into a block a variable has an identifier and a type a variable's type can never change
15	Expressions expressions compute things! an expression yields a value an expression must also have a side- effect a variable can't be used until Definitely Assigned
16	Literals some tokens represent values
17	Operators some tokens represent actions
18	Layout layout tokens to reflect grammatical structure be consistent and conventional here is my personal layout style one space on either side of a binary operator one space after a comma but not before one space after each keyword each statement on a separate line four spaces per indent no space before a semi colon no spaces around method call parentheses no space between a unary operator and its operand
19	Bugs!
