I tried to use ProgressBar in VS 2015 (VB.NET & C#) Community. It works OK except Style. Doesn't matter if I use "Continuous" or "Blocks" style I get "Continuous" style. I also tried in VS 2017 Community and I got the same behavior. It is strange. I downloaded one sample C# project and I am able to select between "Continuous"and "Blocks" styles. I use Windows 10 x64 20H2. I understand if "Blocks" would be disabled but I was able to run a project where everything works OK.
You understand that I use absolutely simple code. I can use "Continuous" style but I like I prefer "Blocks" style.
