XDT Transformation Tool
XDT Transformation is a new feature of ASP.NET 4.0 named Web.Config Transformation.
Scott Guthrie:
"In most real-world deployment scenarios, the web.config file you use for development is different than the one you use for production deployment. Typically you want to change environment settings like database connection-strings, making sure debug is turned off, and enabling custom errors so that end-users (and hackers) don’t see the internals of your application."But the chief problem of this feature - is working only with web.config files.
Config Transformation Tool gives opportunity to use XDT Transformation Syntax like at
Deployment Web Application Project for any files. This tool is very easy, it just run msbuild task, which do this transformation.
You just need to set source file, transformation file and destination file at arguments and run this tool. You can use it for app.config files for WinForms, WPF or Console projects and any other files. You can set this transformation task with nAnt or just set it in Post-Build Event for Project.
