For the folks developing on ESB Applications, this should be quite a common one. Posting it for those who have get prompted for this error (actually a warning) and would want to ignore it in your Visual Studio designer. In my case, I was testing this on BizTalk 2009. It also applies to BizTalk 2010.
Error: A X509 Certificate is required in the model property ‘EncryptionCertificate’ to encrypt any sensitive property in the designer
- Open the file ruleset.config located at:
Path: C:\Program Files (x86)\Microsoft BizTalk ESB Toolkit 2.0\Tools\Itinerary Designer\ruleset.config
- Navigate to the following element
Name: EncryptionCertificateUnder the above element comment out the validator type with name=”EncryptingCertificate validator”
