将我网站上的 ServiceStack 库从 3.9.71 升级到 4.0.33 后，我注意到 ServiceStack.Razor 不再正确呈现页面。它似乎没有读取 layout.cshtml 文件。页面加载时没有布局，也没有错误或警告。我尝试将 layout.cshtml 文件放在 /Views/_layout.cshtml 和 /Views/Shared/_layout.cshtml 中。
除了在升级过程中替换软件包之外，我还对 Web.config 文件进行了必要的更改。这是我的 Web.config 文件中的一个片段。请让我知道这是否有帮助，或者我是否需要提供其他信息。任何帮助，将不胜感激。
