entity-framework - Entity Framework 5コードの最初の無効な列名?

Question

この投稿で質問したことがあります: Entity Framework 5 無効な列名?, しかし、大量のコードのために、問題の原因を検出することは困難でした. だから、誰かがこの問題を解決するのを手伝ってくれることを期待して、別の単純な環境で例外を再現しました:

このシンプルなアプリでは、ウィンドウを閉じるためのボタンと、シミュレーションを追加するためのボタンの 2 つのボタンを備えた wpf ウィンドウを使用します。

私はそれをコードに記入します。

簡単に言うと、例外のメッセージは「Invalid column name Simulation_SimulationID」です。
