digital signature needed for RSocket.core.dll

[clrsky]

@OlegDokuka currently version 0.2.3 is not digitally signed.

Based on discussion done with Reetesh Agarwal's, we were expecting the digitally signed versions to be available in some time .

Any idea when we can expect the package to be signed with valid certificates.

fixed as of 0.2.7 release
