.Synopsis
    Finds the specified or latest MSBuild.
 
.Description
    The script finds the path to the specified or latest version of MSBuild.
    It is designed to work for MSBuild 2.0-15.0 and support future versions.
 
    For MSBuild 15.0+ the command uses VSSetup module from PSGallery.
    If it is not installed then some default locations are checked.
    Thus, VSSetup module is required for not default installations.
 
    MSBuild 15.0+ resolution precedence: Enterprise, Professional, Community,
    another product. If this is not suitable then use VSSetup module directly.
 
    For MSBuild 2.0-14.0 the information is taken from the registry.
 
.Parameter Version
        Specifies the required MSBuild version. If it is omitted, empty, or *
        then the command finds and returns the latest installed version path.
        The optional suffix x86 tells to use 32-bit MSBuild.
 
.Outputs
    The full path to MSBuild.exe
 
.Example
    Resolve-MSBuild 15.0
    Gets location of MSBuild installed with Visual Studio 2017.
