Hello,

Thanks for your inquiry.
Are you using the x64 plugin? I created a ASP.NET Core Web API project using the x64 plugin and then published it directly to Azure, and did encounter the issue you mentioned. However, when I changed the platform of the general settings to 64 Bit (as shown below), it worked fine. Please verify it on your side.

If the issue persists after trying, to help us further investigate your issue, please provide us with your runnable project. You could upload it to the DropBox or OneDrive and then share the download link with us([email protected]) via email.

Hi,

I am not able to find the Plugin.dll.I am working on POC for HTML to PDF conversion using spire.pdf (8.2.2) .net core.

I receive the following error.
- $exception {"The conversion provider cann't be found. \r\nPlease make sure the folder \"plugins\" is under the same folder of Spire.Pdf.dll. For more help, please visit below w System.InvalidOperationException

Please let me know how to resolve this issue.

Thank you,

Hello Dep,

Kindly note that the "plugins" is not a dll but a folder which contain the plugin. You can get the plugins according to the following article: Convert HTML to PDF with New Plugin, choose the corresponding to your system environment, and put the plugins folder under the same folder of Spire.Pdf.dll.

If the issue still exists after downloading the plugins, please provide us with your whole project and your system environment (E.g. Win7 X64) for further investigate. Thanks in advance.

Marcia
