Something need to change in installContra.sh

Since "xbuild tool is deprecated and will be removed in future updates,use msbuild instead" and use "xbuild hula.sln" introduce an error and a warning, I think use "msbuild hula.sln" is better. Actully, I finally successfully compiled contra using "msbuild hula.sln".

The error when using the A command is as follows：
