ASP.NET path to files in the sollution included in the output directory
===

I got an ASP.NET sollution that contains a file that needs to be available in the binary dirctory on every build and I the path of that file. I selected "include in output directory = always" for this file and it gets copied to the bin/Debug directory successfully (so far so good).
But how can i get the path to this file?
The sollution should work on my local pc during Debugging (WebDev server) and when it has been deployed to the IIS.

Stuff I tried that did not work (Debugger output):


    Assembly.GetExecutingAssembly().CodeBase
    "file:///C:/Windows/assembly/GAC_MSIL/System/2.0.0.0__b77a5c561934e089/System.dll"
    
    System.Reflection.Assembly.GetExecutingAssembly().Location
    "C:\\Windows\\assembly\\GAC_MSIL\\System\\2.0.0.0__b77a5c561934e089\\System.dll"
    
    AppDomain.CurrentDomain.BaseDirectory
    "K:\\SollutionLocation\\MySollution\\Source\\Webclient\\"
    
    Environment.CurrentDirectory
    "C:\\Program Files (x86)\\Common Files\\Microsoft Shared\\DevServer\\10.0"
    
    System.Reflection.Assembly.GetAssembly(typeof(SomeClass)).Location
    "C:\\Users\\MyUser\\AppData\\Local\\Temp\\Temporary ASP.NET Files\\root\\9e69f64c\\9ed3edf9\\assembly\\dl3\\b959d3cb\\d3798487_e964cd01\\SomeProject.DLL"
    
    Path.GetFullPath(".")
    "C:\\Program Files (x86)\\Common Files\\Microsoft Shared\\DevServer\\10.0"
    
    Path.GetFullPath("XmlDefinition")
    "C:\\Program Files (x86)\\Common Files\\Microsoft Shared\\DevServer\\10.0\\XmlDefinition"
    
    Path.GetFullPath("~/bin")
    "C:\\Program Files (x86)\\Common Files\\Microsoft Shared\\DevServer\\10.0\\~\\bin"
    
    Request.PhysicalPath
    "K:\\SollutionLocation\\MySollution\\Source\\Webclient\\default.aspx"
    
    HttpContext.Current.Server.MapPath(@"~/Schedule/")
    "K:\\SollutionLocation\\MySollution\\Source\\Webclient\\Schedule\\"

Or am I totally wrong on that approach? I basically need some file (an XSL Transformation sheet) in my SVN that should be accessable via codebehind on my pc and on the IIS and I do not want to use absolute paths.

Searched whereever possible, would really appreciate something that works :)
