Issue when using Blazored / LocalStorage in Azure function #69
Comments
Does this only happen is Azure Functions? I've never tried running a Blazor app from an Azure Function. How does that work? I'm not sure what to suggest on this one, bit outside my knowledge. I've had very little experience with Functions. |
As there has been no more feedback on this issue I'm going to close it as we can't really do anything. |
googling this issue landed me here, to whomever lands here in the future: I had to simply install |
Thanks Hoshani. Your suggestion solved the Blazored.LocalStorage "System.IO.FileNotFoundException: Could not load file or assembly 'System.Text.Json" issue for me. |
I was getting this error too. Not in Azure Functions, just a regular Blazor web app. Strange that the nuget package doesn't pull in System.Text.Json as a dependency. |
I get the same error in a Blazor web app, but with SessionStorage instead of LocalStorage, deployed on IIS. It asks for v. 4.0.1.2 but that version is not available so I can not use the workaround... I have other Blazor apps, running on the same server, using the same version of SessionStorage that are working fine. I think the error comes from After upgrading ASP.NET Core Hosting Bundle on IIS, the error went away: Unhandled exception in circuit 'tlnELVghh4tJIeaayOZaV4CHGjBcxk4oeYq68qqsh3I'. Exception: |
