After switch to new PC and fresh instalation of Visual Studio 2015 update 3 and Telerik Reporting v. 22.214.171.1241 I tried to modify DataSources in report. I have some Data Objects in the same project which uses DataObject attribute for classes as well as DataObjectMethod(DataObjectMethodType.Select) for methods. It is working on old PC without any problems. On fresh installed one when I selects "Show data components only" in data source wizard - it displays nothing. Of course project is builded up before check so assemblies are present.
Do you have any idea what can cause this problem? I spent already few hours on search with no luck so any ideas are welcome.
