title: Why won't Visual Studio for Mac open a project created from SPA templates?
body: <p><strong>Full disclosure: This is the first time I have tried to do any .NET development on a Mac</strong></p>
  
  <p>Visual Studio for Mac will not open an Angular project created at the CLI using dotnet new. Attempts to open the csproj file in Visual Studio for Mac result in an error message: </p>
  
  <pre><code>Could not save solution: /Users/aaron/Projects/ngApp/ngApp.sln" followed by "Load operation failed
  </code></pre>
  
  <p>Created a new .NET Core / Angular app using the "angular" SPA template from the command line by creating a new directory called "ngApp", changing in to that directory, and then typing "dotnet new angular". This generated a project with everything I would have expected inside (including a csproj file). The csproj file seems right based on my experience with the csproj files of projects created using "dotnet new" on Windows. </p>
  
  <p>Attempts to open the csproj file in Visual Studio for Mac result in an error message: "Could not save solution: /Users/aaron/Projects/ngApp/ngApp.sln" followed by "Load operation failed".</p>
  
  <ul>
  <li>.NET Core SDK 2.2.101, </li>
  <li>Node 9.5.0</li>
  <li>NPM version 6.5.0</li>
  <li>Angular CLI 7.1.4</li>
  </ul>
  
  <p>Am I missing something important here? Are there any logs that may help me figure this out?</p>
