nuget update adds nuget.core dependency in mvc web app

Every time I do a nuget update it breaks my deployment.
Somewhere in my solution or project some sort of dependency is added that I cannot find or understand or get rid of.

Today I updated jQuery. Everything seemed fine running locally.
When I deploy to DEV I get an error in the app start up.

Event code: 3005 
Event message: An unhandled exception has occurred. 
Event time: 3/20/2013 4:56:10 PM 

Process name: w3wp.exe 
Exception information: 
Exception type: InvalidOperationException

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.
Right now my app is dead in the water!

Sincerely, Joe
