The below differance are very usefull and cachhe words..... var dynamic Introduced in  C# 3.0 Introduced in  C# 4.0 Statically typed  – This means the type of variable declared is decided by the compiler at compile time. Dynamically typed  - This means the type of variable declared is decided by the compiler at runtime time. Need  to initialize at the time of declaration. e.g.,  var str=”I am a string”; Looking at the value assigned to the variable  str , the compiler will treat the variable  str  as string. No   need  to initialize at the time of declaration. e.g.,  dynamic str; str=”I am a string”;  //Works fine and compiles str=2;  //Works fine and compiles Errors are caught at compile time. Since the compiler knows about the type and the methods and properties of the type at the compile time itself Errors are caught at runtime Since the compiler comes to about the type and the methods and properties ...

From version 2.0 a Code behind page of an asmx file is placed into the app_code folder. .axd :  when enabled in web.config requesting trace.axd outputs application-level tracing. Also used for the special webresource.axd handler which allows control/component developers to package a component/control complete with images, script, css etc. for deployment in a single file (an 'assembly') .config :  web.config is the only file in a specific Web application to use this extension by default (machine.config similarly affects the entire Web server and all applications on it), however ASP.NET provides facilities to create and consume other config files. These are stored in XML format. .cs/vb :  Code files (cs indicates C#, vb indicates Visual Basic). Code behind files (see a...
