更新“Microsoft.jQuery.Unobtrusive.Ajax”没有更改packages.config文件中的版本

Question

我正在使用Visual Studio 2012中的asp.net mvc5 Web项目。现在我运行以下命令来更新Microsoft.jQuery.Unobtrusive.Ajax： -

Install-Package Microsoft.jQuery.Unobtrusive.Ajax -Version 3.2.2 

我知道它已成功安装： -

Attempting to resolve dependency 'jQuery (≥ 1.8)'.
'Microsoft.jQuery.Unobtrusive.Ajax 3.2.2' already installed.
Removing 'Microsoft.jQuery.Unobtrusive.Ajax 2.0.20710.0' from SkillManagementTDMGroup.

Adding 'Microsoft.jQuery.Unobtrusive.Ajax 3.2.2' to SkillManagementTDMGroup.

Uninstalling 'Microsoft.jQuery.Unobtrusive.Ajax 2.0.20710.0'.
Successfully uninstalled 'Microsoft.jQuery.Unobtrusive.Ajax 2.0.20710.0'

现在当我检查packages.config文件时，我发现仍然是jquery.unobstrusive.ajax版本是2.0.20710.0而不是3.2.2如下： -

<package id="jQuery.Ajax.Unobtrusive" version="2.0.20710.0" targetFramework="net45" />

所有人都可以就此问题提出建议吗？
