asp.net 4.5 custom membership provider configurati

• ASP.NET: This method cannot be called during the application's pre-start initialization stage 5 answers

My web site was initially written in MVC 4.0 RC using VS2010, . I have just downloaded and installed VS2012, and upgraded my project to Dotnet Framework 4.5.

In my project I'm using a Custom MemberShipProvider and a custom RoleProvider. On VS2010 it worked like a charm. But now I'm keeping getting a strange Configuration Error:

"This method cannot be called during the application's pre-start initialization phase."

The "system.web -> membership -> providers -> add" line in my web.config is marked red as the source of the problem.

I eliminated the suspicion that the problem has something to do with the migration process, by creating a new MVC 4.0 Project (in VS2012), adding my custom Membership/Role providers, changing the web.config appropriately, and finding that the error reappears!

Digging deeper into the problem - I found the following information in the Application Log:

Exception information: Exception type: InvalidOperationException Exception message: The pre-application start initialization method Start on type WebMatrix.WebData.PreApplicationStartCode threw an exception with the following error message: This method cannot be called during the application's pre-start initialization phase.

This is the relevant custom membership (I have simplified it, but even though the problem is still there) code, only ValidateUser is really overridden:

using System;
using System.Linq;
using System.Web.Security;
using DAL.MyWebSite;

namespace MyWebSite.Security
{
    public class MyWebSiteMembershipProvider : MembershipProvider
    {




        /// <summary>
        /// Verifies that the specified user name and password exist in the data source.
        /// </summary>
        /// <returns>
        /// true if the specified username and password are valid; otherwise, false.
        /// </returns>
        /// <param name="username">The name of the user to validate. </param><param name="password">The password for the specified user. </param>
        public override bool ValidateUser(string username, string password)
        {
            // simplified
            return true;
        }



    }
}

This is the (simplified) RoleProvider:

using System;
using System.Linq;
using System.Web.Security;
using DAL.MyWebSite;

namespace MyWebSite.Security
{
    public class MyWebSiteRoleProvider : RoleProvider
    {


        //readonly MyWebSiteDbContext _context = new MyWebSiteDbContext();
        /// <summary>
        /// Gets a value indicating whether the specified user is in the specified role for the configured applicationName.
        /// </summary>
        /// <returns>
        /// true if the specified user is in the specified role for the configured applicationName; otherwise, false.
        /// </returns>
        /// <param name="username">The user name to search for.</param><param name="roleName">The role to search in.</param>
        public override bool IsUserInRole(string username, string roleName)
        {
            return true;
            //return GetRolesForUser(username).Contains(roleName);
        }

        /// <summary>
        /// Gets a list of the roles that a specified user is in for the configured applicationName.
        /// </summary>
        /// <returns>
        /// A string array containing the names of all the roles that the specified user is in for the configured applicationName.
        /// </returns>
        /// <param name="username">The user to return a list of roles for.</param>
        public override string[] GetRolesForUser(string username)
        {
            return new string[] {"one", "two"};

            //var sm = _context.SalesManagers.Include("PermissionLevel").FirstOrDefault(manager => manager.UserName == username);

            //if (sm != null)
            //{
            //    if (sm.PermissionLevel.Name == "Sales Manager")
            //    {
            //        return new[] { "SalesManagers" };
            //    }

            //    if (sm.PermissionLevel.Name == "Administrator")
            //    {
            //        return new[] { "SalesManagers", "Administrators" };
            //    }

            //} 
            //return null;

        }

    }
}

回答1:

I use my own custom Membership and Role providers in Since MVC2 and ran into this issue when I migrated from MVC3 to 4.

I created a new project in MVC4 / .net4.5 EF5 and had the miss-fortune to encounter this error.

I managed to fix it by doing the following:

Add this to your webconfig appsettings:

  <appSettings>
    <add key="enableSimpleMembership" value="false"/>
    <add key="autoFormsAuthentication" value="false"/>
  </appSettings>

Add your connection string to your memberships and roles providers if not already set:

<membership defaultProvider="MyMembershipProvider">
  <providers>
    <add name="MyMembershipProvider" type="AMS.WebUI.Infrastructure.CustomMembershipProvider" connectionStringName="EFDbContext" />
  </providers>
</membership>
<roleManager defaultProvider="MyRoleprovider">
  <providers>
    <add name="MyRoleprovider" type="AMS.WebUI.Infrastructure.CustomRoleProvider" connectionStringName="EFDbContext" />
  </providers>
</roleManager>

This resolved the issue for me and I hope it can help you.

回答2:

OK let's see if I can explain this right. ASP.NET 4 introduced a new assembly-level attribute: PreApplicationStartMethodAttribute, that is typically used in the Properties/AssemblyInfo.cs file.

ASP.NET MVC 4 standard template comes with a reference to the WebMatrix.WebData assembly. Looking at its code, the AssemblyInfo does have this:

[assembly: PreApplicationStartMethod(typeof(PreApplicationStartCode), "Start")]

So basically, before App_Start is even invoked, the framework will call WebMatrix.WebData.PreApplicationStartCode.Start() which, among other things, does this

// Initialize membership provider
WebSecurity.PreAppStartInit();

And sure enough, like @Ben Pretorius said, that method starts like this

internal static void PreAppStartInit()
{
    // Allow use of <add key="EnableSimpleMembershipKey" value="false" /> to disable registration of membership/role providers as default.
    if (ConfigUtil.SimpleMembershipEnabled)
    {
        ...

So there you have how/why this "automatically" fails. It's really too bad that Microsoft didn't include <add key="EnableSimpleMembershipKey" value="true" /> in the standard Web.config to make it more obvious that "hey there's this SimpleProvider stuff that's setup here".

回答3:

I was also playing around this a bit and looking into the WebMatrix code and finally I think that Ben's solution seems to be the working one.

(I have also tried to play with the assembly references without success. I think with removing the references you just achieved the same as the config settings does - the WebMatrix security was not properly initialized. But I think this is quite a dangerous way. But I'm just guessing here.)

So for me what worked:

<appSettings>
  <add key="enableSimpleMembership" value="false"/>
</appSettings>

<membership defaultProvider="MyMembershipProvider">
  <providers>
    <clear />
    <add name="MyMembershipProvider" type="MyNamespace.MyMembershipProvider" />
  </providers>
</membership>
<!-- this role configuration below uses the SimpleRoleProvider, because I just 
     wanted to replace the membership provider. If you need to replace that one 
     too, just use your own class instead. -->
<roleManager enabled="true" defaultProvider="AspNetSqlRoleProvider">
  <providers>
    <remove name="AspNetSqlRoleProvider" />
    <add name="AspNetSqlRoleProvider" type="WebMatrix.WebData.SimpleRoleProvider, WebMatrix.WebData, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
    <!-- note: WebMatrix registers SimpleRoleProvider with name
         'AspNetSqlRoleProvider'. I don't know why but i kept it. -->
  </providers>
</roleManager>

I have checked the WebMatrix code, and it seems that setting 'enableSimpleMembership' to false is quite harmless. WebMatrix only uses it to initialize the membership/role providers (that can be substituted by the config above) and it enables the forms authentication allowing an alternative configuration way (through app settings) - this is also not necessary, if you have the standard forms authentication properly configured (mainly the 'loginUrl' is the only important player here).

I have also tried to check what the 'autoFormsAuthentication' setting does - but I haven't found anything, so just skipped it. Looks fine still.

I already solved the problem. I found that when you create MVC 4 project in VS2012, the template adds references to some assemblies, among them: webmatrix and Oauth... I just removed those references, and the problem disappeared. I do not know to answer how this solved the problem, but I saw that the Exception comes from WebMatrix Assembly, so for that reason I tried to remove it. Sorry, but i have no time to invest in investigation....
