我有一个针对.net 4.7.1的ASP .Net项目 . 我正在尝试添加the Microsoft.AspNetCore.DataProtection package(这取决于.net标准2.0) .

I thought .net 4.7.1 is part of the .net standard 2.0,但当我尝试添加此包时,NuGet告诉我以下内容 .

它发生在Visual Studio 2012和Visual Studio 2017上 .

Microsoft Visual Studio Community 2017  15.0.26228.4 D15RTWSVC

Microsoft .NET Framework                4.7.02556

NuGet Package Manager                   4.0.0

如何将Microsoft.AspNetCore.DataProtection包添加到.net 4.7.1项目中?

    VS 15.3中添加了NetStandard 2.0支持,您的15.0 RTW版本将无法安装.NET Standard 2.0软件包 .

    使用.NET Standard程序集时,您可能会遇到(经典)ASP.NET应用程序中的问题 . 检查dotnet/Announcements GitHub issue on this topic,具体如下:

    Web应用程序和Web站点不支持自动绑定重定向生成 . 要解决绑定冲突,您需要双击错误列表中的警告,Visual Studio会将它们添加到您的web.config文件中 .
