Powershell 在Windows 10 server got上通过PS远程处理在vNext生成中运行WebTest；System.Data.Entity.Core.ProviderIncompatibleException“；

在TFS vNext构建中，我通过PS远程处理将服务器webtests部署到一个Windows 10测试代理并运行所有webtests。它不稳定，因为有时我会遇到“System.Data.Entity.Core.ProviderIncompatibleException”错误（见下文）

服务器上已安装Visual Studio 2015。sam条件下的相同测试在Windows 7测试代理上运行良好

原因是什么？我如何解决这个问题？非常感谢
