Report veiwer Error in Server RRS feed

  • Question

  • Hi guys,

    I have a question. 

    I have researched about `Could not load file or assembly 'Microsoft.ReportViewer.ProcessingObjectModel, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91'` and I have found a lots of answers that fix this problem but I have not found why it is happen.

    My system is composed by:

     - Business Layer 
     - Data Layer
     - Service Layer
     - Web Layer
     - Api Layer

    Only Service and Web Layers are using Microsoft.ReportViewer. Web and Api have reference to Business, Data and Service Layers.

    When I publish the Web on Azure, it works fine but there is this error when I publish the Api on Azure. They are published in different cloud service.

    My API do not uses Microsoft.ReportViewer, so why `Microsoft.ReportViewer.ProcessingObjectModel` is requested when I hit any endpoint?

  • Hi Rodrigo_Vedovato,

    Thank you for posting here.

    Normally, if you do not use this assembly, the app would not load the assembly. If your code use the method or other property of this assembly, when you run it, it will load this assembly. In your description, Service and Web Layers use the Microsoft.ReportViewer.

    Best Regards,

    Wendy
