Hi,

I installed Umbraco 8 using NuGet and VisulaStudio 2019. When I compile it locally and run the setup it works perfetctly. However, as soon as I publish the site to my host using WebDeploy, I get a server error eith the detail: Could not load file or assembly 'System.Collections.Immutable' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

And a further warning: WRN: Assembly binding logging is turned OFF. To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1. Note: There is some performance penalty associated with assembly bind failure logging. To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

I saw that there was a similar error a few years ago but didn't find the solution there. Since I'm pretty new I'm also a bit lost.

BTW, Umbraco 7.9.0 using the WebHosts installer works. I compiled it for .Net 4.7.2.

Any idea on how to solve it?

Thanks

Ueli
