TestMembershipProvider未顯示任何錯誤，但TestUserProfile顯示以下錯誤：

無法從程序集'System.Web，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a'加載類型'Test.Library.UserAccountProvider.TestUserProfile'。

on語句return (TestUserProfile)Create(username);

Answer 1

也許你應該在行的'type'屬性的末尾添加完整的程序集名稱（“，Test.Library.UserAccountProvider”），如果你的類的位置是name =“TestProfileProvider”？

像這樣 ：

  <add name="TestProfileProvider" type="Test.Library.UserAccountProvider.TestProfileProvider, Test.Library.UserAccountProvider" connectionStringName="SecurityContext" applicationName="Sigma" applicationContext="XpressPago" />

對於'inherits'屬性也一樣：

   <profile defaultProvider="TestProfileProvider" inherits="Test.Library.UserAccountProvider.TestUserProfile, Test.Library.UserAccountProvider">

我認為Create不會選擇該類，因為它嘗試“System.Web”。
當然我認為Test.Library.UserAccountProvider是正確的程序集名稱，如果需要可以修復它...
