body: <p>I search a lot, but I didn't find any useful step by step guide to install and configure and build boost in Windows 10 with VS 2019 Preview. Can anyone of you guide me through this task?</p>

  <p>When I try the boost 1.68, I could run bootstrap.bat successfully, but when I execute b2.exe it gives me the following message:</p>
  
  <pre><code>warning: Did not find command for MSVC toolset. If you have Visual Studio 2017 installed you will need to specify the full path to the command, set VS150COMNTOOLS for your installation, or build from the 'Visual Studio Command Prompt for VS 2017'.
