ASP.Net Compilation and Merge Tool (Part 1 of 2)

ASP.NET Compilation tool is used to compile an ASP.NET Web application either in same machine or to deploy on a target machine such as a production server. It helps application performance because end users do not encounter a delay on the first request to the application while the application is compiled on backend.
Compilation for deployment can be in one or two ways
That removes all files such as code-behind and markup files
That retains markup files. Syntax
aspnet_compiler [-?]
[-m metabasePath -v virtualPath [-p physicalPath]]
[[-u] [-f] [-d] [-fixednames] targetDir]
[-c]
[-errorstack]
[-nologo]
[[-keyfile file -keycontainer container ] [-aptca] [-delaysign]]
Example
Aspnet_compiler -v /WebApp1 -p "c:\MyProjects\WebApp1" -keyfile "c:\MyProjects\KeyWebApp1.sn" -aptca c:\applicationTargetWhy to use ASP.Net Compilation Tool
People always ask, why I use ASP.Net Compilation tool. The answer is “precompiled ASP.Net 2.0 Web Application”. Following are the advantages to use ASP.Net Compilation and Merge Tool. According to MSDN
Security
Performance
Stability Security
Pre-compilation of ASP.Net Application slow down reverse engineering process, because it lacks the abstraction and readability of a high-level language. Performance
Compiled code faster than other scripting languages such as VBScript or ECMAScript because it is a closer to machine code and does not need additional parsing. Stability
Code is checked on compilation for syntax, type safety and other sort of problems by caching error at build process and then you can eliminate these errors.
