"No extensions found" when running Visual Studio Code from source
<p>When I try to install any extension in Visual Studio Code (i.e., by pressing <code>Ctrl+P</code> and then running <code>ext install RustyCode</code>), I get a message that <code>No extensions found</code>.</p>

<p>However, this only happens when I run VS Code directly from source repository. I.e., after:</p>

<pre><code>git clone https://github.com/Microsoft/vscode.git
cd vscode
git checkout 1.0.0
scripts/code.sh
</code></pre>

<p>But, if I run VS Code from <a href="https://code.visualstudio.com/#alt-downloads" rel="noreferrer">official builds</a>, then I'm able to install extensions.</p>

<p>So, how can I enable downloading and installing extensions from Visual Studio Marketplace when I run VS Code directly from source repository? (Is Visual Studio Marketplace integration bundled separately in official builds?)</p>

<p>I'm on Ubuntu/Linux.</p>
