Visual studio 2013 Slow in editing razor files

Question

I just had installed VS2013. When I press Up or Down keys in a razor file editor which it is not pure html and has some razor codes VS 2013 slow down and permanently consume ~25% of CPU and everything is slow until I restart the VS.

I noticed that the problem only occurs when the razor document is reopened. If the document is already open when you open the Solution the problem doesn't occur.

I try many things but none of them fix the problem:

• Disabling Resharper
• Disabling Productivity Power Tools 2013
• Deselecting "Rich client visual experience" in the "Options - Environment"
• Disabling git plug-in or other Source Control: set Current source control plug-in to None

I test it in same machine in VS 2012 and everything was working normal.

Edit: I had tested different scenarios and finally I found out that the following lines cause the problem:

<ul>
    <li style="@(!User.IsInRole("men") ? "display: none" : "")">Menu1</li>
    <li style="@(!User.IsInRole("women") ? "display: none" : "")">Menu2</li>
</ul>

If I remove the style="@(!User.IsInRole("men") ? "display: none" : "")" the problem not occurs anymore. Any idea?

Edit: I had reported the problem to microsoft here please upvote for better & quick support.
