I'm trying to create an EntityDataSource with the new report wizard, but I get a Popup with "Exception has been thrown by the target of an invocation"(Very usefull exception message by the way) before the wizard ends. I've the last version of telerik report(2011 Q3), and I've no other version of telerik reporting installed.
I've one c# class library project, and one other containing the EntityFramework and the generated POCO objects(+datacontext).
Here are some screenshot which show what I've done. I think I've done nothing special :/.
I need to have a first running report at leat friday(the 2.12.2011), so please help :(
Step1: Creating the report
Step 2: Clicking on Add New Data Source...
Step 3: Choosing Entity Data Source type
Step 4: Choosing my connection string(copied in the app.config file, from the app.config file of my EF project, so I now it works)
Step 5: Choosing my dataContext object(which is in another referenced project)
Step 6: Choosing the object context member(in my case, offers
Step 7: Get the wonderfull error!
After that, the data source has been created, but do not work, I see it in the bottom of the report, but it cannot be used anywhere, and if I go again on the report wizard and select the data source, I've the same error than on the Step 7.
What is going wrong and what can I do NOW to get it working
