Unable to cast object of type 'System.Web.Profile.DefaultProfile' to type 'WebApplication1.Profil... (no replies)

Hi .net experts who works with MySQLProvider,

trying to learn MySql Provider.at my first sample attempt.ı wanted to use ProfileProvider for MySql and I thought my ProfileCommon class written for SQL Server should work for MySql Provider too.But t didnt and dont know why.

ProfileCommon Profile = ProfileCommon.GetUserProfile("User1"); this line raises error
Unable to cast object of type 'System.Web.Profile.DefaultProfile' to type 'WebApplication1.ProfileCommon'.

this is my web.config :

......
<system.web>
<authentication mode="Forms" />
<compilation debug="true" targetFramework="4.0" />
<membership defaultProvider="MySQLMembershipProvider">
<providers>
<clear/>
<add name="MySQLMembershipProvider" autogenerateschema="true" type="MySql.Web.Security.MySQLMembershipProvider, MySql.Web, Version=6.5.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" connectionStringName="ConnectionString1" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="true" applicationName="/" requiresUniqueEmail="false" passwordFormat="Clear" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="7" minRequiredNonalphanumericCharacters="1" passwordAttemptWindow="10" passwordStrengthRegularExpression="" />
</providers>
</membership>
<profile defaultProvider="MySQLProfileProvider">
<providers>
<clear/>
<add name="MySQLProfileProvider" type="MySql.Web.Profile.MySQLProfileProvider, MySql.Web, Version=6.5.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" connectionStringName="ConnectionString1" applicationName="/" />
</providers>
</profile>
<roleManager enabled="true" defaultProvider="MySQLRoleProvider">
<providers>
<clear/>
<add name="MySQLRoleProvider" type="MySql.Web.Security.MySQLRoleProvider, MySql.Web, Version=6.5.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" connectionStringName="ConnectionString1" applicationName="/" />
</providers>
</roleManager>

</system.web>
</configuration>



and this is my ProfileCommon Class :

namespace WebApplication1
{
public class ProfileCommon : ProfileBase
{
public static ProfileCommon GetProfile()
{
return Create(HttpContext.Current.Request.IsAuthenticated ?
HttpContext.Current.User.Identity.Name : HttpContext.Current.Request.AnonymousID,
HttpContext.Current.Request.IsAuthenticated) as ProfileCommon;
}

public static ProfileCommon GetUserProfile(string username)
{
return (ProfileCommon)Create(username);
}

public static ProfileCommon GetUserProfile()
{
return Create(Membership.GetUser().UserName) as ProfileCommon;
}

[CustomProviderData("FirstName;varchar")]
public virtual string FirstName
{
get
{
return ((string)(this.GetPropertyValue("FirstName")));
}
set
{
this.SetPropertyValue("FirstName", value);
}
}

[CustomProviderData("LastName;varchar")]
public virtual string LastName
{
get
{
return ((string)(this.GetPropertyValue("LastName")));
}
set
{
this.SetPropertyValue("LastName", value);
}
}
}

}

if I changed this function in ProfileCommon to this:


public static ProfileCommon GetUserProfile(string username)
{
return Create(username) as ProfileCommon;
//return ((ProfileCommon)(Create(username)));
//return (ProfileCommon)Create(username);
}

Profile return always null. and doesnt give error.

ProfileCommon Profile = ProfileCommon.GetUserProfile("User1");

simply can we say MySqlProfileProvider is not much usefull ?

may you provide us a good example howto use Profile in aspnet WebApplication (not aspnet website) ?

simply,Im trying to get /set the profile properties of the user given by name (not logined user.wantto get/set profile details by username)
