找不到 GAC 部署的声明成员资格提供程序程序集

Question

我正在为 SharePoint Foundation 部署创建自定义成员资格提供程序。我已经生成并部署到全局程序集缓存，但在登录页尝试加载时出现错误。我不确定为什么找不到已签名的 GAC 部署的程序集。

说明：处理此请求所需的配置文件时出错。请查看下面的特定错误详细信息并相应地修改配置文件。任何帮助或指导不胜感激。

Answer 1

您是否尝试重置 IIS？应用程序池将 GAC：ed dll：s 缓存在内存中，需要回收才能加载新的应用程序池。

Answer 2

我创建了一个针对 .Net 3.5 的新项目和设置项目，并在其中处理了我的类源代码。（之前的尝试针对 VS 2010 默认净值 4。进入下一个错误（我的类无法加载）但希望这是某个地方的一些愚蠢的错别字。
