Question

我创建了一个azure函数，一切正常。但是，一旦我添加了另一个项目引用，我就会遇到此构建错误。

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

仅当添加此项目参考时，才会发生此问题。否则没有构建错误。我无法找出导致此问题的相关组件。

将项目的.NET sdk版本更新为引用项目中的相同版本，以便azure.webjobs版本将相同。此错误是由于项目中的版本冲突引起的。您可以使用“管理NuGet软件包”选项更新.NET SDK
