This product reached the end of support date on March 31, 2021.

I observed that the agent is only passing host information and not sending any information on .net application.

I suggest you open a support case and have someone from the support team investigate. Be sure to attach your whole log file, not just the snippets.

Also include specific version numbers of Windows and .NET on that machine. If possible, post the mscorlib.dll file.
