Why we need Codedworkflows.cs file

[pravin_bindage]

I created one exe file to add sign image to pdf using c#,It works well in other new process but when i use that exe file in my actual process it throws this error.I’m using start process activity to call exe file. Unexpected error has occurred during the library compilation process:
Could not find file ‘C:\Users\Uipathuser\OneDrive - xxxxxxxxxxxxxxxxxx_SignForm.local\install\CodedWorkflow.cs’.

@Anil_G @supermanPunch @Sudharsan_Ka @Kaviyarasu_N ya do you have any idea? I also installed UiPath.codedworkflows package

@pravin_bindage

As you say its working in other new processes can you try copying your workflow there and check

cheers

[pravin_bindage]

I tried but when i start publishing that new process then again this problem occurs

[Anil_G (Anil Gorthi)]

@pravin_bindage

So you dont have an issue running it in studio?

Is it possible to share the workflow

cheers

[Harshith_Adyanthaya]

Hi @pravin_bindage ,

Did you try invoking the new process into main process instead of using same activities?

Get a backup of your project file and open the project file again and then remove that UiPath.CodedWorkflow package and then reinstall the package

Before reinstalling i get this error
Compilation failed or was cancelled.

Error: System.InvalidOperationException: In order for projects containing coded workflows to be compiled, the UiPath.CodedWorkflows package must be referenced explicitly if none of the imported packages already depend on it., HResult -2146233079

After reinstalling i get this

PDF sharp is available in Windows Compatibility Try the below equivalent code

using System;

                pdfDocument.Save(outputFilePath);
                Console.WriteLine("Modified PDF created in >> " + outputFilePath);
            }
        }
    }
}

I did not compile fully…Should be good…check once
