Hello there,  
I was using zatca sdk  
zatca-einvoicing-sdk-238-R3.2.4\Lib.Net\SDKNETFrameworkTest\SDKNETFrameWorkLib.dll

and It works very good;

these days we deiced to use last available sdk, so we use version 3.3.5 which is based on .NETFramwork 4.8. I try to make demo app to test new zatca sdk version and I got the error that telling the verifing signed xml file is invlaid this is the visual basic Code

Sub Main()

```
    Dim vCert As String
    Dim vPvKey As String
    Dim vXmlDoc As New XmlDocument()

    ' This certificate and privatekey are copied from Folder: zatca-einvoicing-sdk-238-R3.3.5\Data\Certificates
    vCert = "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"
