The Sitecore 5.2.0.1 package contains a file called PrecompiledApp.config, located in the root-folder. Because of this little nasty bugger, you receive this Server Error if you try to add your own class to the solution:

Server Error in '/' Application.

The directory '/App_Code/' is not allowed because the application is precompiled.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I tried all sorts of things to fix it, but ended up contacting Runi from Sitecore. He replied that I should hust remove the PrecompiledApp.config file - and voila! it worked...

• .Net framework 2.0 (!!!)
• SQL server 2005
• Sitecore 5.2.0.1

The application is compiled on these specs - and not tested on anything else... Feel free to download and use it.

If you have any requests or find bugs, feel free to post a request - I'll see if I can find the time the add/fix it...

NOTE: this application is highly inspired by the original Sitecore database installer... I have created an application which does the exact same job, and have just added some features and fixed some bugs.

And off course: THIS SOFTWARE AND THE ACCOMPANYING FILES ARE SUPPLIED "AS IS", WITHOUT ANY WARRANTIES WHATSOEVER WHETHER EXPRESSED OR IMPLIED.... yada yada yada...
