Hi,

I upgraded Umbraco 7 (with uCommerce7 installed) to Umbraco v8 successfully.

After I upgraded uCommerce to v8 (removed UCommerce.Umbraco7 and installed UCommerce.Umbraco8), I started getting a weird runtime error. Unable to resolve type: Umbraco.Core.Services.ServiceContext, service name:.

I checked all dependencies, even commented out all custom services but still stuck on this error.

Spent days on investigating this but no luck. Can anybody help please?

My installed versions are:

• Umbraco 8.16.0

  • uCommerce 8.4.1.19353
  • uCommer.Umbraco8 8.4.1.19353

  Server Error in '/' Application. Unable to resolve type: Umbraco.Core.Services.ServiceContext, service name: Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
