Hello,
I recently updated my project to 9.3.1. Everything seems to work fine, until I refresh a page, and then it crashes and I get the following error. It happens on every page. Do you know what the issue could be?
Thank you.

- The error you are encountering (
System.ObjectDisposedExceptionrelated to Autofac and Blazorise) after upgrading to ABP 9.3.1 with Blazor Server is typically caused by a mismatch or incompatibility between the Blazorise package versions and the ABP/Blazor project dependencies. This is especially common after major upgrades.
To resolve this issue, follow these steps:
Update Blazorise Packages
Ensure that all Blazorise-related NuGet packages in your solution are updated to the latest versions compatible with .NET 8/9 and ABP 9.x. You can do this via NuGet Package Manager or by editing your.csprojfiles.Clean and Rebuild
- Delete the
binandobjfolders in all projects. - Rebuild the solution to clear any cached assemblies.
- Delete the
Check for Duplicate Registrations
- Make sure you are not registering Blazorise services (e.g.,
AddBootstrap5Providers,AddFontAwesomeIcons) in both your Blazor and Host projects. Shared registrations should be in a shared module or only in the host for Blazor Server.
- Make sure you are not registering Blazorise services (e.g.,
Update ABP and Run Bundle
- Run
abp updatein your solution root to update all ABP-related packages. - Run
abp bundleto update static assets.
- Run
Review Dependency Injection Configuration
- Ensure that your DI registrations for Blazorise and other UI components are correct and not duplicated or missing.
Restart Development Environment
- Sometimes, Visual Studio or your IDE may cache old assemblies. Restart your IDE after the above steps.
If the problem persists, try creating a new ABP Blazor Server solution with the same version and compare the package versions and startup configuration.

Thanks - I discovered the solution was moving the functions previously in OnInitializedAsync() to OnAfterRenderAsync(bool firstRender).
