Could not load file or assembly 'Microsoft.CodeAnalysis, version= 1.3.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependenc

Question

An update occurred last night and now I find myself unable to do a ctrl + \'.\' for code suggestions in VS 2015. An error message comes up saying the following:

Answer 1

I found the missing assemblies in the NuGet package (After the first one was resolved there were mulitple otheres): https://www.nuget.org/packages/Microsoft.Net.Compilers/1.3.1-rc

Installed them using GacUtil from the Dev console.

Answer 2

In my case, I was getting this error because my Visual Studio Solution was trying to use TextTransform.exe during a pre-build step in one of the projects, but my local machine didn't have the TextTransform.exe at the path specified by my pre-build step and my first attempt at fixing that was to just copy TextTransform.exe from some other location to where Visual Studio expected it to be. That appears to have caused this problem, because TextTransform.exe has other silent dependencies.

My fix was to change the pre-build steps so instead of looking for the file at

C:\Program Files (x86)\Common Files\microsoft shared\TextTemplating\14.0\TextTransform.exe

it would instead look in the Visual Studio install folder which had a bunch of other files, presumably one of which was a peer dependency of TextTransform.exe

C:\Program Files\Visual Studio\Common7\IDE\TextTransform.exe

That seemed to fix things for me.
