UWP - https certification valiation issue

Vinod Sahu 0

I am trying to call an https api on a payment device, it returns a certificate signed by intermediate CA and that signed by root CA.

I have installed root CA in trusted store of windows, added capability in WPF manifest.

It returns error - Partial chain .

This whole setup works in a console app.

If I add the intermediate certificate in trusted store, it works fine.

Are there any configs that can be set in wpf to fetch intermediate certifcate similar to console app.

Hello Vinod Sahu,

You mentioned "WPF manifest" in your question, but WPF applications don't use manifests in the same way UWP applications do. Based on your description of the sandboxed behavior and certificate validation issues, it sounds like you might be working with a UWP application rather than WPF. Could you confirm which framework you're actually using?

Thank you!
