Entity Framework Coreで"You need to call SQLitePCL.raw.SetProvider(). が発生したときの解決方法"

Posted at

久しぶりの投稿。

問題発生ケース

環境
OS:Windows11
IDE:Visual Studio2022 Windows Form .Net7

Entity Frameworkのチュートリアルを進めていたところ、下記の場所でエラーが発生した。
"You need to call SQLitePCL.raw.SetProvider(). If you are using a bundle package, this is done by calling SQLitePCL.Batteries.Init()".

c# sample.cs
dbContext.Database.EnsureCreated();

対応方法

パッケージマネージャーで下記の通り実行。

PM> install-package system.data.sqlite
PM> uninstall-package system.data.sqlite
PM> install-package microsoft.entityframeworkcore.sqlite

リビルド実行後、再度実行するとエラーは発生しなくなった。
