FIX: "non-readonly field/property access is limited" error when you build a BizTalk Server 2010 project


Consider the following scenario:
  • You have an orchestration in a Microsoft BizTalk Server 2010 or Microsoft BizTalk Server 2013 project in Microsoft Visual Studio.
  • You create the following two types of variables in the orchestration:

    var1: System.Xml.XmlDocument
    var2: System.String
  • You add an expression shape that contains the following code to the orchestration:

    var1 = new System.Xml.XmlDocument();
    var2 = var1. DocumentElement.NamespaceURI;
In this scenario, you receive the following error message when you build this project:
non-readonly field/property access is limited to distinguished fields on class-based messages.
