Resource mapping is stored in IIS metabase and is updated on installation of .Net Framework to point to aspnet_isapi.dll as well.

IIS Application Mappings for aspnet_isapi.dll
.asax(so that can’t be access from outside), .ascx, .ashx, .asmx, .aspx, and .axd (trace.axd).

The Basic use of CultureInfo class is shown here: • How string Comparisons are performed • How Number Comparison & Formats are performed • Date Comparison and Formats. • How resources are retrieved and used. Cultures are grouped into three categories: Invariant Culture : It’s Culture Insensitive. It can be used to build some trial application. It can be also used to build an application with hard-coded expiry date that ignores cultures. But using it for every comparison will be incorrect and inappropriate.

Text Encoding and Decoding using .Net

Namespace: System.Text To read a file, an application must write information about the encoding in which the file was written. So, the application that creates a file must write encoding information, otherwise viewer will see block and question marks in file. Unicode UTF-32 encoding : Represents a character as sequence of four bytes (32 bits). UTF32Encoding class can be used in that perspective. Unicode UTF-16 encoding : Represents a character in 16 bits. UnicodeEncoding class can be used to convert to and from UTF-16 encoding. Unicode UTF-8 encoding : Unicode UTF-8 uses 8-bit, 16-bit, 24-bit, and up to 48-bit encoding. Values 0 through 127 use 8-bit encoding and exactly match ASCII values, 128 through 2047 use 16-bit encoding, and values from 2048 and 65535 uses 24-bit encoding. UTF8Encoding class can be used to convert to and from UTF-8 encoding. ASCII encoding : ASCII encoding encodes Latin alphabets as single 7-Bit ASCII character. It is not well su...

Using TransactionScope Object : A transaction can’t span multiple connections.   Local and distributed transaction ares supported in 1.x you have to Enterpeise seveices library to regiser multiple connections and then call EnlistDistributedTransaction. Distributed Transaction Coordinator is required for Distributed transaction that’s available on windows 2000 & +. In 2.X and later use TransactionScope object. Serializable allows one transaction to complete before the other start. SqlConnectoin support named savpoint to roll back to; that’s an equaliant to save transaction command in MS SQL Server.
