WPF使用SqlLite数据库（EF版本）

1. 添加NuGet包：Microsoft.EntityFrameworkCore.Sqlite
2. 添加DataModel

 public class ResourceMessage
 {
     [Key]//主键
     [DatabaseGenerated(DatabaseGeneratedOption.Identity)]  //设置自增
     public string Id { get; set; }
     public string? OtherKey { get; set; }
 }

3.添加DbContext

  public class DataModel_Test : DbContext
  {
      public DbSet<ResourceMessage> ResourceMessages { get; set; }
      protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
      {
          optionsBuilder.UseSqlite($"Data Source=Test.db");
      }
  }
