[4.5.1-alpha001] FileNotFoundException: Could not load file or assembly 'Microsoft.CodeAnalysis

[0x53A]

After updating to the latest version my call now fails with

System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.CodeAnalysis, Version=1.3.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

I haven't looked too deeply at this, but the only thing that may be missing is a dependency:

Downgrading to 4.5.0-rc1 seems to have fixed this, but I haven't started actually verifying it.

Sounds reasonable, thanks
