Csharp 初始化具有EntityFrameworkCore和不同架构的数据库时引发System.MissingMethodExcept

我在try 初始化数据库时遇到问题.在我的应用程序中，我有两个DbContext，标识DbContext和Auctionhouse DbContext，它们都使用相同的数据库，但使用不同的模式.当我try 使用Update-Database -Context IdentityDbContext命令初始化数据库时，我得到以下异常:

System.MissingMethodException: Method not found: 'System.Data.Common.DbParameter System.Data.Common.DbBatchCommand.CreateParameter()'.
   at Npgsql.NpgsqlCommand..ctor(String cmdText, NpgsqlConnection connection)
   at Npgsql.NpgsqlCommand.CreateCachedCommand(NpgsqlConnection connection)

   at Microsoft.EntityFrameworkCore.Design.OperationExecutor.OperationBase.Execute(Action action)
Method not found: 'System.Data.Common.DbParameter System.Data.Common.DbBatchCommand.CreateParameter()'.

以下是涉及的组件的相关代码:

public class IdentityDbContext 
    : IdentityDbContext<ApplicationUser, IdentityRole<Guid>, Guid>
{
    public const string Schema = "identity";

    public IdentityDbContext(
        DbContextOptions<IdentityDbContext> options) 
        : base(options) { }

    protected override void OnModelCreating(
        ModelBuilder modelBuilder)
    {
        modelBuilder.HasDefaultSchema(Schema);

        base.OnModelCreating(modelBuilder);
    }
}

配置DbContext的ServiceCollectionExtensions.cs文件如下所示:

var connectionString = configuration.GetConnectionString("IdentityConnection");

services.AddDbContext<IdentityDbContext>(options =>
{
    options.UseNpgsql(connectionString, options =>
    {
        options.MigrationsHistoryTable(
            tableName: HistoryRepository.DefaultTableName,
            schema: IdentityDbContext.Schema);
    });
});

如能就如何在创建迁移期间解决此问题提供任何帮助或指导，将不胜感激.谢谢!

Directory.Packages.props文件如下所示:

<Project>
  <PropertyGroup>
    <ManagePackageVersionsCentrally>true</ManagePackageVersionsCentrally>
  </PropertyGroup>
  <ItemGroup>
    <PackageVersion Include="Microsoft.AspNetCore.OpenApi" Version="8.0.0-rc.2.23480.2" />
    <PackageVersion Include="Microsoft.EntityFrameworkCore.Tools" Version="8.0.0-rc.2.23480.1" />
    <PackageVersion Include="NSwag.AspNetCore" Version="13.20.0" />
    <PackageVersion Include="NSwag.MSBuild" Version="13.20.0" />
    <PackageVersion Include="MediatR" Version="12.1.1" />
    <PackageVersion Include="Microsoft.AspNetCore.Identity.EntityFrameworkCore" Version="8.0.0-rc.2.23480.2" />
    <PackageVersion Include="Microsoft.AspNetCore.Identity.UI" Version="8.0.0-rc.2.23480.2" />
    <PackageVersion Include="Npgsql.EntityFrameworkCore.PostgreSQL" Version="8.0.0-rc.2" />
  </ItemGroup>
</Project>

这Directory.Build.props人看起来是这样的:

<Project>
  <PropertyGroup>
    <TargetFramework>net8.0</TargetFramework>
    <TreatWarningsAsErrors>true</TreatWarningsAsErrors>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>
</Project>

我还找不到任何不匹配的地方.除了NSWAG，我已经安装了每个包的所有最新预发行版.
