Thanks for the report! Can you provide a repro sample for your issue?

I have attached sample. Work with Desktop project Not work with wasm project.

Thanks for the report.

This is happening because of this:

Failed to load resource: net::ERR_BLOCKED_BY_RESPONSE.NotSameOriginAfterDefaultedToSameOriginByCoep

It looks like the .NET Wasm host is started with COEP enabled, causing the image to not show up. It's likely to be a .NET update, but in the meantime, you can run your app using dotnet run in the command line, the image will appear.

Ok, for the sample i can run "dotnet run" in my local machine, but for production my Wasm App work in Azure Web Storage, how can fix it?

[jeromelaban]

On the Azure Web Storage, the issue won't be there either. This is specific to the hosting when started from VS 2022.
