Answer 1

あなたはミディアム信託SQLite.NETアセンブリとして構成されたWebアプリケーションを持っていますか完全な信頼が必要ですか？

あなたのweb.configファイルにこれを追加すると、それを修正するかどうかを確認してください：

<system.web> 
    <securityPolicy> 
     <trust level="Full" /> 
    </securityPolicy> 

... 
</system.web> 

それとも、すでに信頼タグを持っている場合は、完全にレベルを変更します。 slolife答えは動作しない場合

Answer 2

、あなたもmsdn (ASP.NET Trust Levels and Policy Files)からこれを試すことができます。

<system.web> 
    <securityPolicy> 
     <trustLevel name="Full" policyFile="internal"/> 
    </securityPolicy> 
</system.web>
