Could not load file or assembly 'Azure.Storage.Blobs' or one of its dependencies. The system cannot find the file specified

I need to implement Azure Storage in a legacy .NET Framework application (4.8.1), I have created a .NET Standard 2.0 Class Library using Azure.Storage.Blobs Nuget Package, as Azure.Storage.Blob is deprecated. When adding the class library as a reference and attempting to call it from the .NET web application the following error is thrown.

System.IO.FileNotFoundException

HResult=0x80070002

Message=Could not load file or assembly 'Azure.Storage.Blobs, Version=12.18.0.0, Culture=neutral, PublicKeyToken=92742159e12e44c8' or one of its dependencies. The system cannot find the file specified.

I have tried rolling back to previous versions of the nuget package but the error is the same.
