Consume WebService

[Dat Bui Quang]

Hi !

I create a webservice with some method (return Dataset) and test successfully !.

I add a new WebForm with datagrid display data from that method and view in browser successfully (web method return dataset and display in datagrid)

But when I use that webservice in other project (compilation successfull) then receive error message below:

May it have to do something with second project? I think Web.config files (of webservice project and test project) may be wrong !

Thanks for answers !
