Java file is not part of a workspace. Intellisense is not available and other issues.

Hi recently installed the Minecraft extension pack to create minecraft mods. I would like to start using this tool to teach students how to write software. I have successfully used eclipse but the amount of setup time is very high. I liked the idea of using visual studio for the development platform because I am familiar with this IDE. However, I have many errors starting off.

1.) I have an error that says: Java file is not part of a workspace. Intellisense is not available
2.) Sometime visual studio 15 gets an error that says the component cache is out of date. Then it crashes visual studio at other times.
3.) I can start minecraft when I execute the code, but it is very slow and glitchy compared to creating minecraft mods in eclipse. How can this be sped up?
