New Post: NuGet.Core with _bin_DeployableAssemblies

nuget update adds nuget.core dependency in mvc
Every time I do a nuget update it breaks my build/deploy.
Somewhere in my solution or project some sort of dependency is added that I cannot find or understand.
Today I updated to jQuery 1.8.20. Everything seemed fine running locally.
When I deploy to DEV I get an error in the app start up.

Why does NuGet do this to me?
I find it very stressful.
The last time this happened I spent most of my day removing every single solitary NuGet package, and adding them all back again.
What a stressfull total pain.

Any suggestions will be appreciated.

Sincerely, Joe
