<#@ assembly name="System.Core" #>
<#@ import namespace="System.Text" #>
<#@ output extension=".xml" #>
<#@ assembly name="EnvDTE" #><# /* This assembly provides access to Visual Studio project properties. */ #>
<#
    var serviceProvider = this.Host as IServiceProvider;
    var dte = serviceProvider.GetService(typeof(EnvDTE.DTE)) as EnvDTE.DTE;
    var solutionDirectory = System.IO.Path.GetDirectoryName(dte.Solution.FullName);
#>


    

The XML attribute "filePath" will equal the Visual Studio's solution directory plus "\MySubfolder\MyFile.exe".
