The notification could not be formatted. RRS feed

  • Question

  • I've developed a custom formatter component to transform complex XML documents, and get the following error when trying to use it:

      The notification could not be formatted.
     <Distributor Id>1</Distributor Id>
     <Distributor Name>NHSDDist1</Distributor Name>
     <Distributor Work Item Id>4</Distributor Work Item Id>
     <Notification Id>7</Notification Id>
      Request for the permission of type System.Security.Permissions.StrongNameIdentityPermission, mscorlib, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 failed.
    DistributorName: NHSDDist1

    After extensive googling, I'm still pretty much none the wiser.

    The dll was created using v1.0.3705, which, I'm guessing is at the root of the problem.

    I've also included the dll code, as I think this possibly has a bearing too.

    using System;

    Any idea on a resolution?
