Background:- My project is of a class library having target .NET framework 4.8 and have installed the nuget Azure.Storage.Blobs(version 12.21.1 which is latest stable) in my class.
I'm encountering a problem with the nuget package dll of "System.Diagnostics.DiagnosticSource". In my error logs it states the Version of the dll as 6.0.0.0 although Azure.Core utilizes version 6.0.0.1. I checked packages.config, csproj, app.config (Having bindingRedirect as well) and all refer to the same package version i.e 6.0.0.1.
I turned the assembly fusion logs on and they have the following:-
\`The operation failed.
Bind result: hr = 0x80070002. The system cannot find the file specified.

When I downgrade my NuGet package from 6.0.0.1 to 6.0.0.0, I encounter a different error: "Could not load file or assembly 'System.Diagnostics.DiagnosticSource, Version=4.0.4.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'."
Attempting to switch from version 6.0.0.0 to 4.0.4.0 results in a compatibility issue with "Azure.Core" and "Azure.Storage.Blobs," which do not support System.Diagnostics.DiagnosticSource, Version=4.0.4.0. Despite having consistent references to version 6.0.0.1 in both my packages.config and the app.config of my new DLL, the error persists.
There was a similar question on stackoverflow, I attempted using it's solution as well that is removed xmlns from assemblyBinding tag in app.config Earlier: Now:
But still the error is showing up. Please suggets some way out.
I removed all the binding redirects from my app.config and added the below under runtime in app.config true
Also, in the package properties I did set the Specific Version to false. This solved my issue.
