以下のエラーが表示されます。これは、ビジュアルスタジオ2015を最初のアップデートにアップグレードした後に始まったようです。私はここでマシンキーの問題であることについていくつかのスレッドを読んだことがありますか?私はどのようにそれを修正し、それを防止するか分からない。現在私はIIS Expressを使用してデバッグでこれを実行すると、ローカルマシンでこのエラーが発生します。ここでデバッグ中に暗号操作中にエラーが発生しました
Cache = db.UserTokenCacheList.FirstOrDefault(c => c.webUserUniqueId == userId);
// place the entry in memory
this.Deserialize((Cache == null) ? null : MachineKey.Unprotect(Cache.cacheBits,"ADALCache"));
