Environment for contributing

[robert-skarzycki]

Hi, all contributors,

What exactly software I need to contribute? I've opened the solution in VS Community 2015 (with VS SDK installed) but VSIX project hasn't been loaded poperly. I've tried VS 2017 RC Enterprise (with VS SDK installed) and the project was loaded, but it cannot be compiled due to error message stating that vsix package manifest must contain "Prerequisities" node.
