RuntimeBinder Exception when binding dynamic items to object properties

Question
-
The following code when used in an alternate solution worked fine, but does not work for this. The only thing that changed was the UI, but I don't see how that has any effect on this code.
dynamic resultObj = JArray.Parse(finalString); foreach (dynamic item in resultObj) { Promotion branchObj = new Promotion() { sCategory = item.sCategory, sExpireDate = item.sExpireDate, sPromoDetails = item.sPromoDetails, sPromoMain = item.sPromoMain, sPromoUrl = item.sPromoUrl, }; promoItems.Add(branchObj); }
the detailed error message is as follows:
'Newtonsoft.Json.Linq.JObject' does not contain a definition for 'sCategory'
Any help would be much appreciated...

Hi S_Gerard,
It seems that you code are correct. I have seen a scenario would cause this error. If one machine had another version of Json.NET installed in GAC, it would produce this kind of error. Please check this on your machine, if you can see Json.NET in GAC, clear the assembly and try your app again.
If you still have concerns, please feel free to let me know.

Hello,
I guess, your final string does not represent an array of objects which have an "sCategory" property.
For which value of finalString the exception is thrown? This helps us to reproduce the problem.Regards,

Hi,
the exception is thrown for all the values, not just sCategory.
finalString does represent an array, I checked this with a breakpoint there. I'm not able to upload an image due to forum restrictions. I'm assuming this problem is due to values of dynamic types in 'item' not being exposed to the client assembly at runtime? but it works fine in an alternate solution.
