AzureデータベースからIdentityUserデータを取得するときのエラー

Question

プロジェクトをAzure App Serviceに公開する前に、シードデータなしでVisual Studioでコードファースト移行を実行しました。 6つのテーブルが作成されました：

1. dbo._MigrationHistory
2. dbo.AspNetRoles
3. dbo.AspNetUserClaims
4. dbo.AspNetUserLogins
5. dbo.AspNetUserRoles
6. dbo.AspNetUsers

は私がcertai場合見つけようとするときWeb.configで

接続文字列：

<connectionStrings> 
    <add name="AuthContext" connectionString="Server=tcp:seraphtest.database.windows.net,1433;Database=learnauth;User ID=seraph@seraphtest;Password=XXXXXXXX;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;" providerName="System.Data.SqlClient" /> 
</connectionStrings> 

AuthContext.cs：

public class AuthContext : IdentityDbContext<IdentityUser> 
{ 
    public AuthContext() : base("AuthContext") { } 
} 

エラーの原因のn IdentityUserが私のコントローラに要求を送信することにより、登録されている、私は次のエラーが発生します：

private UserManager<IdentityUser> userManager; 

public async Task<IdentityUser> Find(UserLoginInfo loginInfo) 
{ 
    // stack trace starts from here 
    IdentityUser user = await userManager.FindAsync(loginInfo); 
    return user; 
} 

このエラーの原因は何ですか？どのように修正できますか？

Answer 1

私は

<connectionStrings> 
    <add name="AuthContext" connectionString="Server=tcp:seraphtest.database.windows.net,1433;Database=learnauth;User ID=seraph@seraphtest;Password=XXXXXXXX;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;" providerName="System.Data.SqlClient" /> 
</connectionStrings> 

から

<connectionStrings> 
    <add name="AuthContext" connectionString="Server=tcp:seraphtest.database.secure.windows.net,1433;Database=learnauth;User ID=seraph@seraphtest;Password=XXXXXXXX;Encrypt=True;TrustServerCertificate=True;Connection Timeout=30;" providerName="System.Data.SqlClient" /> 
</connectionStrings> 

に接続文字列を変更する場合、それはどのようにあなたがあなたの接続文字列を取得するのですか
