Webservice not running

Hi Syncfusion,

i am struggling with loading a local pdf file into pdfviewer
I receive the message:" Web-service is not listening. PDF Viewer depends on web-service for all it's features. Please start the web service to continue."

I am using Visual Studio 2019 community Edition and asp.net.core 3.1 MVC

I tried all the example code but without any success.

Hi Syncfusion,

thanks for your reply,

Your provided code example is working.

In my Project the following code snippet was unknow.

 services.AddControllers().AddNewtonsoftJson(options =>
            {
                // Use the default property (Pascal) casing
                options.SerializerSettings.ContractResolver = new DefaultContractResolver();
            });         

I installed " Microsoft.AspNetCore.Mvc.NewtonsoftJson 3.0 via NuGet and everything is working fine now.

Thanks for your support.

Hi Syncfusion,

i was judging a little bit to soon.

My Project is working on localhost, but not after deploying  on my Windows Server 2019.

Here I still receive the Message: " Web-service is not listening. PDF Viewer depends on web-service for all it's features. Please start the web service to continue."

On localhost everything is working fine.

Hi Ernst, 
    
We suspect that issue is due to the write access permission is denied in the environment so the reported issue may occur. We will create the pdfium.dll based on the operating system during the runtime of the control. So can you please try copying the below provided x64 and x86 folder and paste inside the folder(bin\Debug\netcoreapp2.1) in your environment to resolve the issue or enable the write permission for that folder?     
 
 
Note: 
·       Kindly use both the client and server-side of the same version in your project  
·       Ensure whether the Pdfium dll will be created in your project during runtime. Else we can also place the pdfium assemblies in any of the production environment locations and refer to the path by using the ReferencePath  API.  
 
 
For example:  
   
If the Pdfium assembly is available in this path C:\Pdfium\x64 or D:\Pdfium\x86, the reference path should be  PdfRenderer.ReferencePath = "C:/";  
   
The parent folder has to be provided as the path in the ReferencePath API.  
   
  
Note: Provide this path in the Load method of the PDFViewerController.cs  
  
PdfRenderer PdfRenderer = new PdfRenderer();  
 PdfRenderer.ReferencePath = @"C:/";  
  
 
Kindly try it and revert with the modified sample, if you still have concerns about this.  
 
Regards, 
Dhivya.
