Installing Jenkins for .NET builds

install-dotnet45-build.ps1

<#
    .NET 4.5 Build Installation script
    (run with administrative rights)
    
    You can get the netfx45_dtp.msi (and .cab file) by downloading the Windows SDK
    http://msdn.microsoft.com/en-us/windows/hardware/hh852363.aspx
    Run the sdk and have the installer download the files for later use.
    
    You can get the vs_isoshell.exe by downloading the Visual Studio Isolated Shell.
    http://www.visualstudio.com/downloads/download-visual-studio-vs    (That's for 2013)
    Run the installer and you will have the Microsoft.WebApplication.Targets file.
