Could not find property 'Now' on type 'System.DateTimeOffset' in Blazor WASM #38673

Closed mkstephenson closed 2 years ago

mkstephenson commented 2 years ago

Describe the bug

After publishing a Blazor WASM site to Azure Web Apps from Visual Studio, I get a System.InvalidOperationException: Could not find property 'Now' on type 'System.DateTimeOffset' when a Radzen Datagrid attempts to fetch data from EF Core InMemory on startup (no user input required). If started from Visual Studio (debug mode), it works fine.

To Reproduce

The failed instance I attempted to deploy can be found at https://jigsawprogressdisplay.azurewebsites.net/. The source code for this can be found at https://github.com/mkstephenson/Jigsaw-Definition-Parser/tree/master/Jigsaw-Progress-Display. In this case I just tried to deploy the source code to an Azure Web App (Free Plan) using the VS 2022 publish wizard and got this error.

The property is being trimmed away during publishing. Have a look at https://docs.microsoft.com/aspnet/core/blazor/host-and-deploy/configure-trimmer to see some possible workarounds for this.

I would consider removing EF from the equation since it's causing this issue. Looking at your code, it sounds like you might need to store results either in a persistent database or the browser's local storage.

mkstephenson commented 2 years ago

Even if I disable trimming completely with <PublishTrimmed>false</PublishTrimmed>, it still comes up with this error. However the setting <TrimMode>copyused</TrimMode> allows the application to run. Could it be that the PublishTrimmed setting doesn't grasp for some reason with Blazor WASM? Even with the trim mode set to copyused (or publishtrimmed set to false), I get some null reference exceptions when.

Oddly enough, if I publish it to a static web host, it works fine...

Could it be that the PublishTrimmed setting doesn't grasp for some reason with Blazor WASM?

It should work. It could be possible that you were seeing (browser) cached binaries when you first tried it, but publishing to a different host invalidated it. Regardless, given you have a workaround, I'll mark this as resolved.
