Find All References to a DLL, in Powershell

Visual Studio confuses me, and it is slow. I wanted to find all the assemblies/projects that contained references to System.Web.Mvc. Instead of loading up Visual Studio, I just did this.

 gci -recurse -filter "*.csproj" | 
     ?{ select-string "System.Web.Mvc" -path $_ }

Faster than loading Visual Studio, I promise.
