MVC4: UserIsInRole - Unable to connect to SQL Server database

Question

Breaking my head around with this, yesterday it worked fine and today it seems to be broken:

This line is generating the error:

@if (Roles.IsUserInRo         


        

Answer 1

For my use case, adding the following line in the web.config file fixed it!

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

Answer 2

Adding this:

[InitializeSimpleMembership]

To the top of the HomeController fixes the issue.

Answer 3

I found that using UserManager.IsInRole(User.Identity.GetUserId(), "Admin") solved the problem for me. Cheers
