The ASP.NET Team are trying to do something better than editing the project.json by hand.

Question: project.json is going away? Sadface

What were the things we liked? It was small, contained NuGet information, and could be edited by hand. Damian does not want to lose any of those benefits, and that is why they are working in several steps to complete this migration. Additionally, the team is building tooling at the command line so that you don't have to work with the project file directly. Consider a possible npm-like command like “dotnet install json.net –save” to add a NuGet package to your project. There will be first class commands like this available.
The new MSBuild will not have a complete list of every file, so that should reduce the size of the build file. It will still be XML, but the team is committed to making that experience better for all .NET projects. This will be an enhanced MSBuild that has all of the best parts of project.json
