In a Blazor InteractiveServer application, using the ASP.NET Identity Library, I call:
Microsoft.AspNetCore.Identity.UserManager`1.GetClaimsAsync(TUser user)And it throws (full stack trace below).
Microsoft.EntityFrameworkCore.Query - An exception occurred while iterating over the results of a query for context type 'LouisHowe.web.Areas.Identity.Data.UserDbContext'.System.InvalidOperationException: Invalid operation. The connection is closed.The claims table has 34 entries so reading the entire table, if requested (it isn't) is fast.
The one non-standard part of all this in my app is I have class ExIdentityUser : IdentityUser where I add a public bool Enabled { get; set; }. And so my DbContext is UserDbContext : IdentityDbContext<ExIdentityUser>.
This is occurring inside my ExAuthenticationStateProvider : ServerAuthenticationStateProviderGetAuthenticationStateAsync() method.
Why is this closing the connection in this call?
