Why it is still verifyingthe SSL even if i ignore this

We encountered an issue while attempting to convert the .cs file to the .NET 6 framework. When we tried to upgrade the .NET framework, it resulted in the removal of assemblies from the project, and the namespace "System.activity" is causing an error.

Could you kindly assist us in converting the attached .cs file to the .NET 6 framework?

I disabled the SSL verification, but still it is giving error, please help.

Thank you.
