I have upgraded my .NET 6 umbraco 10 website to Umbraco 11.1. I changed the target framework to .NET 7 before upgrading which went fine. Apart from changing some usings here and there, the application built just fine and I could go through with the update procedure and access the backoffice. But when I try to access the site itself I get the following error:

Just want to know if anyone else is experiencing the same issues?!

These are the only Nuget packages I have installed

I can make a workaround, which is adding the missing package as a Nuget package and adding the following to the project file:

<GenerateRuntimeConfigDevFile>true</GenerateRuntimeConfigDevFile>

Not perfect, but it does the job for now until there is a proper fix.
