This article presents a generic approach to applying LINQ queries to tree like structures. Using T4 templates for code generation, LINQ to VisualTree (WPF), LINQ to WinForms, and LINQ to FileSystem APIs are constructed.

using System.Resources;
using System.Runtime.CompilerServices;
using System.Runtime.InteropServices;

// General Information about an assembly is controlled through the following 
// set of attributes. Change these attribute values to modify the information
// associated with an assembly.
[assembly: AssemblyTitle("LinqToVisualTree")]
[assembly: AssemblyDescription("")]
[assembly: AssemblyConfiguration("")]
[assembly: AssemblyCompany("Scott Logic Ltd")]
[assembly: AssemblyProduct("LinqToVisualTree")]
[assembly: AssemblyCopyright("Copyright © Scott Logic Ltd 2009")]
[assembly: AssemblyTrademark("")]
[assembly: AssemblyCulture("")]

// Setting ComVisible to false makes the types in this assembly not visible 
// to COM components.  If you need to access a type in this assembly from 
// COM, set the ComVisible attribute to true on that type.
[assembly: ComVisible(false)]

//In order to begin building localizable applications, set 
//<UICulture>CultureYouAreCodingWith</UICulture> in your .csproj file
//inside a <PropertyGroup>.  For example, if you are using US english
//in your source files, set the <UICulture> to en-US.  Then uncomment
//the NeutralResourceLanguage attribute below.  Update the "en-US" in
//the line below to match the UICulture setting in the project file.

//[assembly: NeutralResourcesLanguage("en-US", UltimateResourceFallbackLocation.Satellite)]


[assembly: ThemeInfo(
    ResourceDictionaryLocation.None, //where theme specific resource dictionaries are located
  //(used if a resource is not found in the page, 
  // or application resource dictionaries)
    ResourceDictionaryLocation.SourceAssembly //where the generic resource dictionary is located
  //(used if a resource is not found in the page, 
  // app, or any theme specific resource dictionaries)
)]


// Version information for an assembly consists of the following four values:
//
//      Major Version
//      Minor Version 
//      Build Number
//      Revision
//
// You can specify all the values or you can default the Build and Revision Numbers 
// by using the '*' as shown below:
// [assembly: AssemblyVersion("1.0.*")]
[assembly: AssemblyVersion("1.0.0.0")]
[assembly: AssemblyFileVersion("1.0.0.0")]
