System.Threading.Tasks.Dataflow, Version=5.0.0.0 is a dependency required by Dianoga. Is it possible you are already referencing a different version of that DLL in your solution? If so can you change it to 5.0.0.0?
I was not referencing a different version, but instead, the Sitecore 10 solution did not have the dll included. I copied the missing System.Threading.Tasks.Dataflow.dll file to the Sitecore solution itself and this fixed the issue. My initial thought was any referenced dlls would be included in the Sitecore solution or the Dianoga solution. This was an incorrect assumption on my part.
While doing the Manual install and an install where I pulled the dll from a project via NuGet, I get the Could not load file or assembly 'System.Threading.Tasks.Dataflow error. I tried updating the System.Threading included package via NuGet as well as updating the reference manually to the correct version, but still run across the same error.
I am on Sitecore 10.1 and it looks like the latest version I've seen someone else reference is Sitecore 10.0. The .Net4.8 version is the one I used, same as our instance of Sitecore. Also, I updated the Kernel, MVC, and SXA references in the project to the one that is currently being use by the instance that throws the error.
Is there something else that needs updated to make sure I am using the right items to fix this error?
