I searched Tools > Options, but where in VS10 can I turn off or change the default highlighting for the new Razor view on the @nuggets in ASP.NET MVC 3?
Razor only adds one entry to Fonts & Colors, "Razor Code". That controls the background color given to Razor Code nuggets. The rest of the colors are the same as the C#/VB colors. The "@" character itself and Razor keywords like "model" and "section" use the same color as the ASPX "<%" tag ("HTML Server-Side Script", thanks to another Andrew for digging up the specific entry).
If you'd rather we had separate entries for some of these, please email us and suggest that: razorvs@microsoft.com
The syntax highlighting for razor is based on the c#/VB default highlighting. So you'll have to change those settings to see any changes in a cshtml file highlighting. Might be a good feature request...I don't know.
In Visual Studio 2015
Tools -> Options -> Environment -> Font and colors
The name of the property is HTML Razor Code Background Change the Item background to the color you like.
