I manage to fix the problem by changing the file permissions to accept the IIS_IUSRS using the https://academy.bpmonline.com/documents/technic-sdk/7-13/development-fi… guide. (Note: To find the file i used the search engine from the windows file explorer)

Dear Pedro,

Yes the solution is to edit file permissions as it is described in the Academy article you provided. Good luck in your development!

Best regards,

Oscar

Hello.

According to this article step 1 in the References section of the project, add dependencies from the following libraries:

• System.Web.Extensions.dll – class library included in .NET Farmework;
• Terrasoft.Core.dll – library of base bpm'online server core classes. It can be found using the following path: [Bpm'online setup catalog]\Terrasoft.WebApp\bin\Terrasoft.Core.dll;
• Terrasoft.Nui.ServiceModel.dll — application service class library. It can be found using the following path: [Bpm'online setup catalog]\Terrasoft.WebApp\bin\Terrasoft.Nui.ServiceModel.dll;
• Terrasoft.Common.dll – library of base bpm'online server core classes. It can be found using the following path: [Bpm'online setup catalog]\Terrasoft.WebApp\bin\Terrasoft.Common.dll.

And then your using directives will work.

Hello,

Thanks for you reply.

I have already added reference for above dependencies. But still its not working.

See below code snippet:

I've just created a console app and all works fine. Maybe you use an old version of .NET Framework or reference wrong dlls... Compare your code with mine:

Peter Vdovukhin,

Have you used core console application or normal one?

I have used normal one. See below:

Issue has been resolved now. It was framework version issue. It requires .Net Framework 4.7.1 or above.

Thanks.
