Add dotnet add|list|remove project commands for solution files

The CLI needs to provide a way for users to manipulate the solution file (SLN file).

Below is a mini-spec of the command.

Usage

`dotnet add <project_or_solution> project <project>

Top level Verbs

• add
• list
• remove

Arguments

• <project_or_solution>
  • A project or a solution path
• <project>
  • Path to the project file to include in the SLN file. Has to be a relative path.

Defaults

• If the <project> is not present, we will try to see if there is a project in the current directory; if there is, it will be added, if not, an error is displayed
• If the <project_or_solution> is not present, we will check the current directory for either a project file or a sln file.
  • If neither are found, an error is displayed
  • If more than one is found or if there is both sln and a project file present, an error is displayed prompting the user to specify which file the operation should work on.

Notes

• This command adds a project to a solution if it works on an SLN file. In case a project file, it will add a <ProjectReference> to the project in question.
• The command will make absolute paths of the project being added relative to the solution file/project being added. This is done to avoid messy breaks when moving machines.

Examples

• dotnet add project "../path/to/project.csproj"
  • Add a project found at the specified path to the solution file
• dotnet remove project "../path/to/project.csproj"
  • Remove a project found at the specified path to the solution file
• dotnet list path/to/solution.sln project
  • List out all of the projects and configurations from the solution;

For website project, how important is that for you to be able to add on a mac? I don’t think we’ve considered this yet.

I think it’s important if only so that there is feature parity across platforms. We can do this in VS proper, so the expectation is that the dotnet sln command should be able to do it, too.

Add a way to set the default (startup) project(s): From the ASP.NET perspective the scenario is that I have a Web API service that my front end talks to. When I invoke dotnet run it would be good to start both.

This is exactly the scenario I was thinking of, so I am certain that having it in dotnet sln would be appreciated by many.
