I have an ASP.NET MVC 4 application. I used NuGet to update all of the NuGet packages that were installed when I created the application. One of the packages was Microsoft.B
I'll agree that this can happen when your packages folder is under source control. If you like to have it there, instead of removing the bindings you can check it all out, remove the package with the NuGet Package Manager, and then check in after wards.
