Error in Blazor App When Upgrading from 5.4.1 to 5.4.2 or Higher

[saulyt]

I tried upgrading my business library and Blazor application from version 5.4.1 to 5.5.1 and got the the following error in both a Blazor Server and Blazor Webassembly version of the application:
InvalidOperationException: The AuthorizationPolicy named: 'Csla:GetObject|NameofMyBusineesClass, Version=VersionOfMyLibrary, Culture=neutral, PublicKeyToken=null' was not found.

I got the error for each item in my NavMenu that is using a CSLA authorization rule for the policy :

<AuthorizeView Policy="@(CslaPolicy.GetPolicy(Csla.Rules.AuthorizationActions.GetObject, typeof(NameofMyBusineesClass)))"> <li class="nav-item"> <NavLink class="nav-link text-dark" href="mypage"> <span class="fa fa-gavel" aria-hidden="true"></span> My Page </NavLink> </li> </AuthorizeView>
I tried downgrading to 5.4.2 and still got this error. Reverting to 5.4.1 fixed the issue. Is there a known breaking change that was made from 5.4.1 to 5.4.2 that would cause this? I tried comparing the 2 releases but nothing stands out to me that would cause this.

Thank you.

Not that I know of. There are a couple types that need to be registered with DI on startup to support CSLA claims - I wonder if they aren't being registered somehow?

        services.AddTransient<IAuthorizationPolicyProvider, CslaPermissionsPolicyProvider>();
        services.AddTransient<IAuthorizationHandler, CslaPermissionsHandler>();

Thanks Rocky! That fixed it. I don't understand why it worked with 5.4.1 without those 2 registrations but I'll take it.
