RPA C# - PROCESS DEVELOPMENTS IN C#

In my company we are developing a process to pass data from Siebel and from Topace, the processing of the data that we extract is complex and we want to use the library of the company that is in C#. Can you recommend any tool compatible with these applications and that can be programmed 100% in C # ?Or at least programmable from C#. We have already tested Automation Anywhere and Uipath and they do not work. Any recommendation? I have been told about Blueprism but I can not find a version to prove it
