EntityFramework Firebird数据库优先

问题描述

我正在尝试使用Nuget软件包中的Firebird EF从数据库创建模型。我正在运行以下命令：

Scaffold-DbContext "User=SYSDBA;Password=xxxxxxx;Database=XXXXXXXXX;DataSource=XXXXXXXXXX;Port=3050;Dialect=3;Charset=NONE;Role=;Connection lifetime=15;Pooling=true;MinPoolSize=0;MaxPoolSize=50;Packet Size=8192;ServerType=0;" Firebirdsql.EntityFramework.Firebird -OutputDir Models

我收到此错误：

`System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
 ---> System.TypeLoadException: Could not load type 'Microsoft.EntityFrameworkCore.Internal.ProductInfo' from assembly 'Microsoft.EntityFrameworkCore,Version=3.1.1.0,Culture=neutral,PublicKeyToken=adb9793829ddae60'.

解决方法

我已经从nuget包中安装了Microsoft.VisualStudio.Web.CodeGeneration.Design。
