String to XNamespace Implicit Conversion inside a BizTalk Orchestration

I am a bit confused by what I see and hence headed over to SO.

I am developing a BizTalk (2010) Orchestration and I am wanting to parse an incoming XML message. I just need to retrieve then number of times a particular node is repeating. I could have used XPath. But, I chose to use LinqToXml.

I have created a variable of type System.Xml.Linq.XNamespace and inside an expression shape, I am assignning it a string value.. say http://mycompany/v1.0. This is a perfectly valid C# statment, as there is an implicit conversion from String to XNamespace (MSDN link).

But the Orchestration will not compile at all. I get this error cannot implicitly convert type System.String to System.Xml.Linq.XNamespace.

And if I dont use the XNamespace variable and directly run LinqToXml on the incoming message like this

MessageCount = MyXElement.Elements("{http://mycompany/v1.0}ListOfNotifications").Elements("{http://mycompany/v1.0}Notification").Count();

I get a cannot convert from String to XName error. Even this is confusing.

I am using BizTalk 2010 and C# 4.0. Can someone explain if I am missing something? I have tried all these code snippets using LinqPad and I get the expected response. So, there are no typos or missing references.

I opted to use the XPath option to retrieve the values that I needed, instead of using LinqToXml. The code that I ended up writing looks like below:

xpath(myOrchVariable, "string(/*[local-name()='InputRootNode' and namespace-uri()='http://my/name/space'])")
