I\'m getting the following exception when trying to call GetDatabase method of the MongoClient class after adding a new configuration using VS conf
Could not load file or assembly 'System.Buffers, Version=4.0.2.0…'
Solution
1) use CMD(run as Administrator ) and type
cd xxxx(xxxx\packages\System.Buffers.4.5.1\lib\netstandard2.0))
run
gacutil /i System.Buffers.dll
Then, when you finish it, please run update-package -reinstall under package manager console to reinstall the package.
2) you can try to change Version=4.0.2.0 to Version=4.0.3.0 in csproj file.
Besides, there is a similar issue you can refer to.
