How do I fix Delphi Prism ASP.NET error: “Parser Error Message: 'Oxygene' is not a supported language”

Question

I have written an ASP.NET web application (not site) in Delphi Prism. Everything works fine on my devlopment machine, but when I install it on a test server I get the following error:

Server Error in '/MyApp' Application.
Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

Parser Error Message: 'Oxygene' is not a supported language.

Source Error:

Line 1:  <%@ Application CodeBehind="Global.asax.pas" Inherits="MyApp.Global_asax" Language="Oxygene" %>


Source File: /MyApp/global.asax    Line: 1 

I've read everything I can find on the web. Several articles mention a RemObjects page (http://devcenter.remobjects.com/articles/?id={B549AFB8-04C8-4574-B185-30DE14369E66}) which unfortunately, no longer exists.

Some links suggest that you can just change Language="Oxygene" to Language="C#". Trying this produces a different error:

Compiler Error Message: CS1061: 'ASP.login_aspx' does not contain a definition for 'ForgottenUsernameLinkButton_Click' and no extension method 'ForgottenUsernameLinkButton_Click' accepting a first argument of type 'ASP.login_aspx' could be found (are you missing a using directive or an assembly reference?)

Anybody else experienced these problems?

1. There are several ways to solve this issue. The easiest way: If you control the server is by installing the command line edition.
2. Another way is precompiling, it: You'll need the Web deployment Project to do this. When you do this, make sure to uncheck the updatable option.
3. With the august 2010 build you can copy the .compiler, .codemodel, .pdb, .cirrus to Bin/, then to your web.config add something like:

<system.codedom> <compilers>
<compiler language="Chrome" extension=".pas" type="RemObjects.Oxygene.CodeDom.OxygeneCodeProvider, RemObjects.Oxygene.CodeModel, Version=4.0.0.800, Culture=neutral, PublicKeyToken=3df3cad1b7aa5098" />
<compiler language="Oxygene" extension=".pas" type="RemObjects.Oxygene.CodeDom.OxygeneCodeProvider, RemObjects.Oxygene.CodeModel, Version=4.0.0.800, Culture=neutral, PublicKeyToken=3df3cad1b7aa5098" /> </compilers> </system.codedom>

Note that in this requires that the version number (4.0.0.800) has to match the dll version of the CodeModel dll you have.
