visual-studio-2010 - MSBUILD 4.0 在 AJAX 扩展上失败

Question

我们有一个 .Net 2.0 Web 应用程序，并将解决方案和项目转换为 Visual Studio 2010(它们是 Visual Studio 2005)。我们将离开针对 Framework 2.0 的项目。该应用程序包含 Ajax 扩展。我们完成了转换，并且可以使用 Visual Studio 在服务器上成功构建项目。但是，当我们尝试通过 MSBUILD 4.0 构建项目时，在使用 ajax 控件的页面上会出现错误，如下所示:

error BC30451: 'ScriptManager' is not declared. It may be inaccessible due to its protection level. error BC30002: Type 'System.Web.UI.ScriptManager' is not defined. error BC30002: Type 'System.Web.UI.UpdatePanel' is not defined. error BC30002: Type 'System.Web.UI.UpdateProgress' is not defined.

这个东西以前工作得很好，通过 Visual Studio 构建时也能正常工作。我们需要做什么来修复这些错误？

Answer 1

在配置 TFS Build service 2008 以使用 MSBuild 4.0 后，我自己也遇到了同样的问题。在转换项目之前一切正常，然后转换为 2010 格式并切换到 MSBuild 4 突然找不到 1.0.61025.0 AJAX 库。

结果发现缺少一个指向 MS Ajax 扩展安装位置的注册表项。

在我的开发盒上， key 应位于(64 位操作系统)

HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\.NETFramework\v2.0.50727\AssemblyFoldersEx\ASP.NET AJAX Extensions

被放置在 HKEY_CURRENT_USER 中。 (32位操作系统:删除Wow6432Node部分)

在构建服务器上，该 key 完全丢失(本地存在的用户配置文件的注册表配置单元中都没有该 key )。

该键的默认值应该指向 MS Ajax Extensions 安装目录，在我的例子中是

C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET 2.0 AJAX Extensions\v1.0.61025

在构建服务器上重新创建 key 后，我们的解决方案在 MSBuild 4 下成功构建。

直到现在(在 MSBuild 3.5 下)它为何能够成功构建，对我来说仍然是个谜。也许程序集搜索算法略有变化，现在更具限制性。

希望有帮助。
