Freezing jQuery NuGet Package Version

jQuery v2.0.0 was released last month, and it does not support Internet Explorer 6/7/8. If you use NuGet to include jQuery in your .NET projects, your jQuery files might be updated to this latest version without old IE compatibility. You can force NuGet to keep v1.9.1 when you update your solution's packages, but you have to manually edit the package file for each project with jQuery.

A project's packages.config file can be found in the root directory of that project (where the .proj file is). Open each packages.config file and look for a line similar to this one:

<package id="jQuery"
            version="1.9.1" 
            targetFramework="net40" />

(The targetFramework attribute may be different)

Adding an allowedVersions attribute allows you to control what version will be used by NuGet during updates. Here's an example:

<package id="jQuery"
            version="1.9.1"
            allowedVersions="[1,2)"
            targetFramework="net40" />

allowedVersions="[1,2)" tells NuGet to grab the newest version that falls between v1.0 and v2.0 (excluding v2). This will likely be v1.9.1, the most current version before v2.0.0.
