Question

我刚升级到Mvc 5.2.0.0并在浏览器（IE9）中启动Web应用程序时开始出现此异常：

[MissingMethodException：找不到方法：＆＃39; Boolean System.Web.WebPages.BuildManagerWrapper.IsNonUpdateablePrecompiledApp（System.Web.Hosting.VirtualPathProvider，Microsoft.Internal.Web.Utils.IVirtualPathUtility）＆＃39;。] < / p>

[stack trace snipped]

从this MSDN Forums link我明白，很可能是某些旧版本的System.Web.WebPages.dll在“临时ASP.NET文件”中徘徊不去。夹。我清理了临时ASP.NET文件夹，但无济于事。我已经清理并重建了解决方案，但没有运气。我还检查了对DLL的引用 - 它们都已正确更新。

我的Web.config（相关部分）如下所示：

Answer 1

重新安装Microsoft ASP.NET网页NuGet包将解决您的问题：

Install-Package Microsoft.AspNet.WebPages

Answer 2

在我的情况下，问题是GAC版本和NuGet版本之间存在冲突，因此当我删除c:\Windows\Microsoft.NET\assembly\GAC_MSIL\System.Web.WebPages文件夹并进行重建时，它开始正常工作而没有此异常。

我想前段时间我用MVC 4安装了System.Web.WebPages，当我尝试使用MVC 5时，它仍然使用GAC版本，因为它仍然有3.0.0版本，而不是3.2，因为它有实际上。

升级到MVC 5.2.0.0导致异常＆＃34;找不到方法：＆＃39;布尔System.Web.WebPages.BuildManagerWrapper.IsNonUpdateablePrecompiledApp＆＃34;
