Background:- My project is of a class library having target framework .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 web.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.
