我試圖創建一個實現MySQL實體框架的項目。我已經添加了EntityFramework，MySql.Data和MySQL.Data.Entities NuGet包。我也安裝了mysql-connector-net-6.7.4。我試圖刪除和刪除所有這些東西，但我仍然得到下面的錯誤。我已經將它作爲服務器添加到項目中，並且已經能夠打開db並拉下test_table。我已經使用MySQL連接，並能夠通過Visual Studio連接到數據庫。我不斷收到此錯誤。MySQL實體框架試圖添加時拋出異常
它在以下代碼的最後一行失敗。
sql123456Entities context = new sql123456Entities();
test_table cookie = new test_table
{
this_is_cool = "Yes it is",
this_is_cooler = 32,
but_is_it_the_fonz = "Yeah!"
};
context.test_table.Add(cookie);
異常消息（內部異常爲null）

你有什麼版本的組裝，如果有？ – ChrisBint
我在所有程序集中都有6.7.4.0以及版本和指向的連接器。我不知道爲什麼它要求這個特定的版本。 – Recursor
db是MySQL 5.5.34所以我更高的版本應該仍然適用它（它要求版本6.5.5）。我只是不明白爲什麼它要求這個版本，以及爲什麼我提供的版本不起作用。我也不知道如何給它一個它想要的，因爲我從最近的NuGet包中獲得了這個。 – Recursor
