I am stuck at the step of creating Echo Bot. Followed all the steps here https://microsoft.github.io/copilot-camp/pages/custom-engine/agents-sdk/02-agent-with-agents-sdk/
When i expand on Program.cs the output gives different types of errors , like "Unable to find package Microsoft.agents.Hosting.aspnet.core. No packages exist with this id in source"
and NU1101 Errors.
Is there some other way to get around this? Followed every step as it was written.
