dotnet workload install commands
Visual Studio on Windows can install .msi files for each workload pack. Note that the concept of a "Visual Studio workload" is different than a ".NET workload".

public double Right { get; set; } 
public double Left { get; set; } 
public double Y { get; set; } 
public double Height { get; set; }
