We tried all steps got so far for umbraco upgrade from 7 to 8 but still we face below error :
-> System.TypeLoadException: Could not load type 'Umbraco.Core.PropertyEditors.PropertyValueTypeAttribute' from assembly 'Umbraco.Core, Version=8.0.0.0, Culture=neutral, PublicKeyToken=null'.
A little bit of a late response as I just came across something similar myself, but the ultimate cause of my issue was that I had a NutGet package installed which was no longer supported in version 8.
The package was replaced with an alternative which supported Umbraco 8 thankfully so I was able to swap it out without loosing my functionality.
The best bet if you (or anyone in a similar boat) comes across this is to gradually uninstall any NuGet packages which are not required by Umbraco itself and re-run the project until you have found the cause of the problem, then its just a case of hoping there is an alternative package available so you don't need to modify your source code too much!
Could not load type 'Umbraco.Core.PropertyEditors.PropertyValueTypeAttribute
Hello,
We tried all steps got so far for umbraco upgrade from 7 to 8 but still we face below error :
-> System.TypeLoadException: Could not load type 'Umbraco.Core.PropertyEditors.PropertyValueTypeAttribute' from assembly 'Umbraco.Core, Version=8.0.0.0, Culture=neutral, PublicKeyToken=null'.
Any solution to fix above error ?
