No matter what board i selected, it always showing this error, please help, thanks!

This means that you are either missing that board configuration file, or have it in the wrong place. Please verify that this file exists by looking under <SDKDrop>\ZeligBuild\Host\bin\Debug\ and searching for a file called Microsoft.Llilum.BoardConfigurations.STM32F401.dll. If it doesn't exist, you found your problem.

If it does exist, that means that your SDK config is looking in the wrong place for it. You can try to fix that by opening the mbed_simple_STM32F401.FrontEndConfig file, and uncomment the -CompildationSetupPath flag. If that doesn't work, I highly recommend following the new SDK setup steps, which are outlined in my post here: #182

There will be an official wiki on these soon
