I am using this code to find the certificate by its thumbprint. certificate exists in certificate manager in personal certificate store but this code is not finding that cer

Answer 1

I was able to resolve issue by writing a console application that retrieve all certs on certificate and output the thumbprint id. I copied the console output and inserted the thumbprint exactly. No issues. Seems like copying from the MMC console causes issues even though the data looks similar. I used this site as starting point to reading all certificates.
