无法构建/发布 Azure 数据工厂应用程序

Question

我尝试在 Visual Studio 2015 中创建的每个数据工厂应用程序，甚至是示例应用程序，都无法构建或发布，原因是：

“对象引用未设置为对象的实例。”每个 .json 文件都有错误。

我是否缺少一些重要的配置或需要添加到项目中的一些依赖项？谢谢

Answer 1

我们对此有一个未解决的错误，并将在我们的下一个版本中修复。在构建过程中会引发错误，但您仍然应该能够继续发布。我们将对此进行进一步调查，以了解为什么您也被阻止发布。感谢您的反馈！

Answer 2

这是扩展程序中的错误。我在 Visual Studio 2015 中遇到了同样的错误，但如果你从 VS 2013 打开这个项目（你需要下载 separate extension），它应该可以正确构建和发布。

Answer 3

重新安装 Azure SDK for Visual Studio。

Answer 4

我也有同样的问题。 Visual Studio 2015 提供 Microsoft Azure SDK 2.8.2 作为更新，并告诉当前安装的版本是 2.8.1，当我尝试更新它时，Web 平台安装程序告诉 2.8.2 已安装并拒绝再次安装。

此外，当我尝试重建 DataFactory 项目时，我收到以下警报。

查看日志，我发现以下消息：

我遇到了同样的问题，这是因为机器上启用了fips 算法策略。

分辨率：

通过 regedit 禁用 FIPS 算法策略并重新启动 Visual Studio。

地点：
