CSLA in VSTO Excel Addin

San S posted on Wednesday, August 19, 2009

I am using CSLA in VSTO Excel addIn project. The application working fine with 2 tier mode but in 3 tier mode I am getting the following error:

"Principal must be of type BusinessPrincipal, not System.Security.Principal.GenericPrincipal".

It would be helpful if any body reply the solution for same.

Thanks

---------------------------------------------------

I trace the issue and found the issue exactly at:

result = Deserialize(wsvc.Fetch(Serialize(request)));

Error Message:
"Principal must be of type BusinessPrincipal, not System.Security.Principal.GenericPrincipal"

This code works when using a local dataproxy but then when switching to calling a WebServicesProxy get this error.

any help would be great.
