.net-standard

问题 I've just created a fresh project using dotnet new web . My Google-foo may be failing me, but I didn't find anything relating to my answer (please link to another SO answer, or relevant documentation if I've missed something obvious).

问题 From the .NET APIs catalog, I understand that the Microsoft.Win32.Registry class is declared in the .NET Standard + Platform Extensions 2.0 package in an assembly Microsoft.Win32.Registry, Version=4.1.1.0, PublicKeyToken=b03f5f7f11d50a3a . I've created a class library which targets .NET Standard 2.0, and here's a simple class: public class NetStandardClass { public string GetHklmRegValue() { var lmKey = Microsoft.Win32.Registry.LocalMachine; var softwareKey = lmKey.OpenSubKey("Software");

问题 I am calling a .net standard 2.0 library from a framework 4.7.2 test project sucessfully. If I take my .net standard 2.0 dll (SBD.Standard) and create a new winforms project that references it then I get asked to add Microsoft.EntityFrameworkCore, then Microsoft.EntityFrameworkCore.SqlServer, then Microsoft.Data.SqlClient and then my project runs successfully. (Although it would be ideal if the extra packages were added automatically) However trouble occurs if I try to distribute my library
