.Synopsis
    Finds the specified or latest MSBuild.
 
.Description
    The script finds the path to the specified or latest version of MSBuild.
    It is designed for MSBuild 17.0, 16.0, 15.0, 14.0, 12.0, 4.0, 3.5, 2.0.
 
    For MSBuild 15+ the command uses the module VSSetup, see PSGallery.
    If VSSetup is not installed then the default locations are used.
    VSSetup is required for not default installations.
 
    MSBuild 15+ resolution: the latest major version (or absolute if -Latest),
    then Enterprise, Professional, Community, BuildTools, other products.
 
    For MSBuild 2.0-14.0 the information is taken from the registry.
 
.Parameter Version
        Specifies the required MSBuild major 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.
        Known versions: 17.0, 16.0, 15.0, 14.0, 12.0, 4.0, 3.5, 2.0
.Parameter MinimumVersion
        Specifies the required minimum MSBuild version. If the resolved MSBuild
        version is less than the minimum version then an error is thrown.
.Parameter Latest
        Tells to select the latest minor version if there are 2+ products with
        the same major version. Note that major versions have higher precedence
        than products regardless of -Latest.
 
.Outputs
    The full path to MSBuild.exe
 
.Example
    Resolve-MSBuild 16.0x86
    Gets the location of 32-bit MSBuild of Visual Studio 2019.
 
.Example
    Resolve-MSBuild x86 15.0 -Latest
    Gets the location of the latest 32-bit MSBuild, and asserts that its
    version is at least 15.0.
 
.Example
    Resolve-MSBuild -MinimumVersion 16.3.1 -Latest
    Gets the location of the latest MSBuild, and asserts that its version is at
    least 16.3.1.
