PushSharp filling up machine keys folder?

[fedcas-assaabloy]

What version of PushSharp are you using?

PushSharp V 4.0.10

Describe your issue:

Our server has been using PushSharp for years, and last week we noticed that the folder "C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys" in our server has millons of temp files which filled up the disk.
Later, we realized that using the X509Certificate2 constructor with the "byte[] rawData" parameter is not recommended because it creates these temp files.
The only code that uses this constructor in our backend is PushSharp.

Is this a common issue? Are we doing something wrong?
Regards.
