The Role Manager feature has not been enabled

Question

Got the following ProviderException        The Role Manager feature has not been enabled    So far so good    Is there somewhere a method that can be called to check if the Role Manager has been enabled or not

You can do this by reading from the boolean property at:

System.Web.Security.Roles.Enabled

This is a direct read from the enabled attribute of the roleManager element in the web.config:

<configuration>
  <system.web>
    <roleManager enabled="true" />
  </system.web>
</configuration>

I found this question due the exception mentioned in it  My Web Config didn t have any  lt roleManager gt  tag  I realized that even if I added it  as Infotekka suggested   it ended up in a Database exception  After following the suggestions in the other answers in here  none fully solved the problem   Since these Web Config tags can be automatically generated  it felt wrong to solve it by manually adding them  If you are in a similar case  undo all the changes you made to Web Config and in Visual Studio    Press Ctrl Q  type nuget and click on  Manage NuGet Packages   Press Ctrl E  type providers and in the list it should show up  Microsoft ASP NET Universal Providers Core Libraries  and  Microsoft ASP NET Universal Providers for LocalDB   both created by Microsoft   Click on the Install button in both of them and close the NuGet window  Check your Web config and now you should have at least one  lt providers gt  tag inside Profile  Membership  SessionState tags and also inside the new RoleManager tag  like this    lt roleManager defaultProvider  DefaultRoleProvider  gt       lt providers gt          lt add name  DefaultRoleProvider  type  System Web Providers DefaultRoleProvider  System Web Providers  Version 2 0 0 0  Culture neutral  PublicKeyToken NUMBER  connectionStringName  DefaultConnection  applicationName       gt       lt  providers gt   lt  roleManager gt   Add enabled  true  like so    lt roleManager defaultProvider  DefaultRoleProvider  enabled  true  gt   Press F6 to Build and now it should be OK to proceed to a database update without having that exception    Press Ctrl Q  type manager  click on  Package Manager Console   Type update-database -verbose and the Seed method will run just fine  if you haven t messed elsewhere  and create a few tables in your Database  Press Ctrl W L to open the Server Explorer and you should be able to check in Data Connections   DefaultConnection   Tables the Roles and UsersInRoles tables among the newly created tables

Here is the code that you need to put in your Account Controller in MVC5 and later to get the list of roles of a user   csharp public async Task lt ActionResult gt  RoleAdd string UserID        return View await          UserManager GetRolesAsync UserID   OrderBy s   gt  s  ToList         There is no need to use Roles GetRolesForUser   and enable the Role Manager Feature

If you are using ASP NET Identity UserManager you can get it like this as well   var userManager   Request GetOwinContext   GetUserManager lt ApplicationUserManager gt      var roles   userManager GetRoles User Identity GetUserId       If you have changed key for user from Guid to Int for example use this code   var roles   userManager GetRoles User Identity GetUserId lt int gt

I found 2 suggestions elsewhere via Google that suggested a  making sure your db connectionstring  the one that Roles is using  is correct and that the key to it is spelled correctly  and b  that the Enabled flag on RoleManager is set to true  Hope one of those helps  It did for me   Did you try checking Roles Enabled  Also  you can check Roles Providers to see how many providers are available and you can check the Roles Provider for the default provider  If it is null then there isn t one

If you got here because you re using the new ASP NET Identity UserManager  what you re actually looking for is the RoleManager   var roleManager   new RoleManager lt IdentityRole gt  new RoleStore lt IdentityRole gt  new ApplicationDbContext        roleManager will give you access to see if the role exists  create  etc  plus it is created for the UserManager
