While upgrading .net project from 6 to 8, I got error says: could not load file or assembly 'Microsoft.Extensions.Configuration.Abstractions, Version=8.0.0.0.

Steps I performed to troubleshoot are:

1. Clean Solution
2. build solution
3. Clean packages form local
4. restored packages
5. Tried adding Microsoft.Extensions.Configuration.Abstractions package with different versions 6/7/8/9 but nothing is working it is keep on giving error.

Please try to provide a sample project demonstrating the issue so we can help tell you what exactly the problem is. My guess here is your project is referencing some other aspnet package with a different version than the one of the configurations abstraction version.

Seems like this is coming from Azure Functions: https://github.com/Azure/azure-functions-host/blob/255b7e59538b9ab677d653daf347b3b0afa70dc9/src/WebJobs.Script/ScriptHostBuilderExtensions.cs#L280

As @tarekgh suggests there is some component that isn't updating. I know Azure Functions control some of the versions of these assemblies when using the "in-process" model, so it could be that you're compiling against one thing but running against a different thing.
