Hi Team,
I have a question about Power Automate Custom Connector Using C# Code. I want to perform RSA Encryption; however, I received an error when I uploaded this code on cloud. The C# script works proper in my localhost; however, the following error occurs in the Custom Connector.
"Failed to provision compute for custom code. Request failed with error 'Code: Bad Request. Message: script.csx(73,28): error CS1061: 'RSACryptoServiceProvider' does not contain a definition for 'ImportSubjectPublicKeyInfo' and no accessible extension method 'ImportSubjectPublicKeyInfo' accepting a first argument of type 'RSACryptoServiceProvider' could be found (are you missing a using directive or an assembly reference?).'. The correlation ID is '3cec6288-8267-45e7-8956-ad050e993949'."
