找不到 SQLite 方法：'IntPtr SQLitePCL.sqlite3.get_ptr()'

Question

我正在尝试在 .Net Standard 2.0 项目中使用 c# 和 microsoft.data.sqlite 实现 SQLite 数据库。当我调用 connection.Open() 时，我不断收到错误“找不到方法：'IntPtr SQLitePCL.sqlite3.get_ptr()'”我已经下载了以下 Nuget 包：<ItemGroup>    <PackageReference Include="Microsoft.Data.SQLite" Version="2.2.6" />    <PackageReference Include="Microsoft.Data.Sqlite.Core" Version="2.2.6" />    <PackageReference Include="SQLitePCLRaw.bundle_green" Version="2.0.0" />    <PackageReference Include="SQLitePCLRaw.core" Version="2.0.0" />    <PackageReference Include="SQLitePCLRaw.lib.e_sqlite3" Version="2.0.0" />    <PackageReference Include="SQLitePCLRaw.provider.e_sqlite3" Version="2.0.0" />    <PackageReference Include="SQLitePCLRaw.provider.e_sqlite3.netstandard11" Version="1.1.14" />  </ItemGroup>我执行如下：private static SqliteConnection _sqlConnection = new SqliteConnection(@"Data Source = myPath");public static Int64 InsertTransaction(string stringToInsert)        {            SQLitePCL.Batteries_V2.Init();            StringBuilder sqlToExecute = new StringBuilder();            sqlToExecute.Append("INSERT INTO table");            sqlToExecute.Append("(columnName) ");            sqlToExecute.Append("VALUES(' " + stringToInsert+ "')");            using (SqliteConnection connection = _sqlConnection)            {                connection.Open();                SqliteTransaction transaction = connection.BeginTransaction();                SqliteCommand sqlCommand = new SqliteCommand(sqlToExecute.ToString(), connection, transaction);                sqlCommand.ExecuteNonQuery();            }        }一切都建立起来了。在运行时，当执行以下块时，我得到：“未找到方法：'IntPtr SQLitePCL.sqlite3.get_ptr()'”on Connection.Open();

将 Microsoft.Data.Sqlite 和 Microsoft.Data.Sqlite.Core 包更新到 Entity Framework Core 版本 3.0.0 将解决该问题。这是我的 package.config 参考：
