ERROR: Cannot override the Shared Resource Provider context obtained from the Office Server. This API can be used only when an Office Server context is either internally unavailable or defined

I was getting above error while working with BDC object model; actually I have custom code which will interact with SQL Session Provider instance and try to open SSP database.

Code: 

SqlSessionProvider.Instance().SetSharedResourceProviderToUse(“SSPName”);

I have found out that I need to change my custom code to work properly to remove error, I got very good reference from http://blogs.msdn.com/syedi/archive/2009/05/28/populating-the-bdc-field-of-a-splistitem-from-client-application.aspx link, which provided me BDC object model code with example.

Thank you!

ERROR: The type or namespace name 'ApplicationRegistry' does not exist in the namespace 'Microsoft.Office.Server' (are you missing an assembly reference)

I was working with BDC object model and accessing BDC application definition file from my custom ASPX page, I have included correct assembly for 'ApplicationRegistry' class but still it was giving me above error, after sometime I have realized that actually it’s looking for different assembly name to be included into page.

i.e. Microsoft.SharePoint.Portal (in microsoft.sharepoint.portal.dll).

After adding Microsoft.SharePoint.Portal assembly into page, I didn’t get any error :)

 Good Job!
