How to create Solution file with dotnet core CLI : <p>I cannot find a way to create a new solution file using the dotnet core CLI commands described in <a href="https://docs.microsoft.com/en-us/dotnet/articles/core/tools/dotnet-sln" rel="noreferrer">https://docs.microsoft.com/en-us/dotnet/articles/core/tools/dotnet-sln</a>.</p>

<p>I ran the commands: </p>

<ul>
<li><code>dotnet new  web -n webtrain</code></li>
<li><code>dotnet new  classlib -n core</code></li>
</ul>

<p>after that, the projects were created correctly, but now I want to create a solution file to group them all, but I cannot find the right command to do that. Anyone knows how to do that?</p>
