TestMembershipProvider未显示任何错误，但TestUserProfile显示以下错误：

无法从程序集'System.Web，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a'加载类型'Test.Library.UserAccountProvider.TestUserProfile'。

on语句return (TestUserProfile)Create(username);

也许你应该在行的'type'属性的末尾添加完整的程序集名称（“，Test.Library.UserAccountProvider”），如果你的类的位置是name =“TestProfileProvider”？

像这样 ：

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

对于'inherits'属性也一样：

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

我认为Create不会选择该类，因为它尝试“System.Web”。
当然我认为Test.Library.UserAccountProvider是正确的程序集名称，如果需要可以修复它...
