我正在使用Visual Studio Enterprise 2015。
以下是更多截图：

您已经安装了Microsoft.Xrm.Sdk版本6，但您需要8版本，以便与您的Microsoft.Xrm.Sdk.Workflow兼容

您可以将Microsoft.Xrm.Sdk升级到8，也可以将Microsoft.Xrm.Sdk.Workflow降级到6。

我刚刚解决了这个问题。我将Microsoft.CrmSdk.corepassemblies包（包含Microsoft.Xrm.Sdk）恢复为6.1.2，它构建得很好！但是，我会注意到，更新Microsoft.CrmSdk.CoreSassemblies包将破坏它，我不知道如何更新项目bin/coretools目录中过期的Microsoft.Xrm.Sdk，因为Microsoft.CrmSdk.CoreSassemblies包的更高版本似乎不再使用该目录。
