问题 Is it possible to msbuild a project that was created for .NET 4.x against the .NET 5 SDK without upgrading the project in VS? I have a .NET 4.7 library project that I compile for .NET 4.x using msbuild (and this issue is easily reproducible by creating a "Class Library (.NET Framework)" project for .NET 4.7). I want to build it for .NET 5, so I tried dotnet msbuild /property:TargetFrameworkVersion=net5.0 /property:TargetFrameworkIdentifier=.NETCoreApp Microsoft (R) Build Engine version 16.8.0

问题 Can someone explain the the OAuth2 JWT token generation and verification in .Net Core? 回答1: First You need to setup ADFS with a client id and redirect URL, then get a JWT token from ADFS server. See this post http://blog.scottlogic.com/2015/03/09/OAUTH2-Authentication-with-ADFS-3.0.html After that, if you are using .Net Core with JWT Bearer Token you need to export ADFS signing certificate using the following powershell commands: $certRefs=Get-AdfsCertificate -CertificateType Token-Signing

问题 EF Core: I need to get the name of the table as the name of the entity, not dbset, also, I need the Id to be "tableName"+"Id" .

I started with this code that works: foreach (var entity in modelBuilder.Model.GetEntityTypes()) { var builderEntity = modelBuilder.Entity(entity.Name); // make table name to be entity name builderEntity.ToTable(entity.DisplayName()); // make Id
