.net 8 SignalR AddMicrosoftIdentityWebApp Authentication

[carlberg74]

Hi,

After some struggling, I got SignalR authentication to work with Azure AD in .net 7.

This by providing the accesstoken as option to HubConnectionBuilder (options.AccessTokenProvider) and using AddJwtBearer OnTokenValidated to set the token as claim on the context.Principal.AddIdentity
and in the Hub, use [Authorize(AuthenticationSchemes = JwtBearerDefaults.AuthenticationScheme)].
All this so I can use Context.User in the Hub.

But something has changed with .net 8 it seem.. as that dont seem to work anymore..

using .net sdk 8.0.100 and packages:

<PackageReference Include="Microsoft.AspNetCore.SignalR.Client" Version="8.0.0" />       
<PackageReference Include="Microsoft.Identity.Web" Version="2.16.0" />
<PackageReference Include="Microsoft.Identity.Web.UI" Version="2.16.0" />
<PackageReference Include="Microsoft.Identity.Client" Version="4.58.1" />

Anyone got this working and could maybe provide some info/example?
