Package Version Updates

Package	Old Version	New Version
Microsoft.EntityFrameworkCore.Sqlite	6.0.1	8.0.8

Microsoft.Data.SqlClient	2.1.7	5.2.0
Microsoft.Data.Sqlite.Core	6.0.1	8.0.8
Microsoft.AspNetCore.Diagnostics.EntityFrameworkCore	6.0.1	8.0.8
Microsoft.AspNetCore.SpaServices.Extensions	6.0.1	8.0.8
Microsoft.AspNetCore.SpaProxy	6.-	8.0.8
Microsoft.AspNetCore.Components.WebAssembly.Server	6.0.1	8.0.8
Microsoft.AspNetCore.Components.WebAssembly	6.0.1	8.0.8

Microsoft.VisualStudio.Web.CodeGeneration.Design	6.0.1	8.0.5

Deprecated Package Removals

• Microsoft.AspNetCore.ApiAuthorization.IdentityServer (6.0.1): Removed from BlazorWasm Server. AppDbContext migrated from ApiAuthorizationDbContext to IdentityDbContext. IdentityServer-related code removed from Program.cs.
• OidcConfigurationController: Deleted (was IdentityServer-specific).
• Microsoft.AspNetCore.Components.WebAssembly.Authentication: Removed from BlazorWasm Client (OIDC auth flow removed to match server-side IdentityServer removal).
• Microsoft.Extensions.Http: Removed from BlazorWasm Client (no longer needed without auth message handler).
• VueCliMiddleware (6.0.0): Removed from Stencil and Vue2 projects. Vue2 Startup.cs updated to use UseProxyToSpaDevelopmentServer instead of UseVueCli.
• IdentityServer config: Removed from appsettings.json and appsettings.Development.json.

Client-Side Auth Changes (BlazorWasm)

• App.razor: Replaced CascadingAuthenticationState + AuthorizeRouteView with simple RouteView
• Program.cs: Removed AddApiAuthorization() and BaseAddressAuthorizationMessageHandler
• Authentication.razor, LoginDisplay.razor, RedirectToLogin.razor: Simplified/cleared (auth removed)

Design Decisions

• SpaServices.Extensions kept for React/Stencil/Vue2: These projects use UseSpa() and UseSpaStaticFiles() APIs extensively in their Startup.cs. SpaProxy does not provide these APIs, so SpaServices.Extensions was updated to 8.0.8 instead of being replaced.
• SpaProxy used for Vue3: The Vue3 project already had UseSpa() commented out and uses the SpaProxy pattern, so it was updated to SpaProxy 8.0.8.
• Korzh.EasyQuery packages remain at 7.4.0 — compatible with .NET 8.

Review & Testing Checklist for Human

• Build each updated project with dotnet build to confirm NuGet package compatibility
• Verify the BlazorWasm AdHocReporting app works without authentication (IdentityServer was fully removed from both server and client)
• Verify Vue2 project works correctly with UseProxyToSpaDevelopmentServer replacing VueCliMiddleware (the Vue dev server now needs to be started separately before the .NET app)
• Test that EasyQuery functionality (search, reporting, data filtering) works as expected

Notes

• .NET Framework 4.x projects (AspNet4/, WinForms/EqDemoWinFormsNet4/, Wpf/EqDemoWpfNet4/) were intentionally left unchanged
• Projects already on net8.0 (Razor-Mvc samples, Angular AdvancedSearch, Angular AdHocReporting) were not modified
• The Program.cs and Startup.cs files use patterns compatible with .NET 8
• Snyk security/license checks show 10 pre-existing failures unrelated to this upgrade
