Hi,
We have sharepoint 2013 farm and it is protected from the UAG and it is going to be in WAP in June’2016. There is requirement to develop Provider hosted app and access SharePoint from CSOM. I could not able to access and its returning access error :- The remote server returned an error: 500 Internal Server Error.
I used PnP core: GetWebLoginClientContext also and it doesn’t work. and also this URL is not working.
Please reply if you have sample code?
