还有一个“Microsoft.jQuery.Unobtrusive.Validation”，我应该在删除jQuery包之前卸载它。

现在我尝试(重新)安装jQuery包，以及之前删除的所有依赖包。 “Microsoft.jQuery.Unobtrusive.Validation”包打破说：

Attempting to resolve dependency ‘jQuery (≥ 1.8)’.
Attempting to resolve dependency ‘jQuery.Validation (≥ 1.8)’.
Attempting to resolve dependency ‘jQuery (≥ 1.3.2 && ≤ 1.6)’.
Updating ‘jQuery 1.8.0’ to ‘jQuery 1.4.1’ Failed.
Unable to find a version of ‘Microsoft.jQuery.Unobtrusive.Validation’ that is
compatible with ‘jQuery 1.4.1’.

是吗？我需要使用最新的jQuery(2.0.xx)！

我应该注意类似的“Microsoft.jQuery.Unobtrusive.Ajax”包没有这个’bug’。安装没有问题。

PS。现在我尝试安装(非Microsoft)jQuery.Validation …

这是错误日志：
