How can I share the data of a dictionary between two appdomains in the same process

I have a program in which I am creating two appdomains A and B . I want to share a dictionary between them. Basically I am creating the dictionary in appdomain A. At this stage, for each key in the dictionary the value part is initialized to null. Then appdomain B needs to access this dictionary and fill in the values for the corresponding keys. After this, A will use the updated dictionary. Could someone please tell me how can I go about do开发者_JAVA技巧ing this. It would be great to have a very small sample example outlining the procedure. Thanks in advance

You cannot share an object between two appdomains. Have a look at .net Remoting or WCF if you need to share data between two or more appdomains.

I don't know much about sharing across AppDomains but have you tried AppDomain.SetData() and AppDomain.GetData()? If that doesn't work, everyone else pretty much says use WCF or if your project is older then Remoting.
