System.IO.FileLoadException: Could not load file or assembly Microsoft.Extensions.Logging.Abstractions

Hi All

I have integrated the MongoDB to my existing project which is .NET FrameWork 4.8.

I have created a new class library for mongo and referenced to other libraries

But I'm getting error as below in my development hosting environment as below.

Referenced and main startup class library is having Microsoft.Extensions.Logging.Abstractions with 7.0.1 as Latest, but MongoDB.Driver supports Microsoft.Extensions.Logging.Abstractions >= 2.0.0, i tried by changing versions but no luck

and in log its showing versions which i'm not using and i tried with those too...

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Start with the stack trace from MongoDB.Driver.ClusterBuilder.CreateClusterFactory and the calls in DataRepository.cs at lines 25, 31, and 216. Compare the referenced Microsoft.Extensions.Logging.Abstractions versions in the .NET Framework 4.8 application and hosting environment; done means the MongoClient can be created without the assembly binding exception.
