Unable to compile the code in .Net 4.5.2 version

[ugn1986]

Hi,
We tried to use this Nuget package to use bulk insert operation but we were unable to compile to code as the target framework of our project is 4.5.2. We saw that Microsoft.Azure.CosmosDB.BulkExecutor is build in .Net 4.5.1 version.
Please let me know if there is any specific reason that we cannot go with any higher version or kindly update the version.
Thanks in advance.
