Oracle (OracleClient) data source not showing up in Visual Studio 2015 for SSRS

Question

I'm currently working with SSRS 2014 reports with visual studio 2013. We have been asked to use visual studio 2015, but I ran into an issue with the data sources missing in 2015.

In 2013 I saw the following data sources:

In 2015 I see the following data sources:

Is there any configuration that will allow me to use OracleClient or even show both data providers?

Answer 1

Open your Registry editor and navigate to HKCU\Software\Microsoft\VisualStudio\12.0_Config\DataSources, resp. HKLM\Software\Wow6432Node\Microsoft\VisualStudio\12.0_Config\DataSources

Compare the branch with HKCU\Software\Microsoft\VisualStudio\14.0_Config\DataSources, resp. HKLM\Software\Wow6432Node\Microsoft\VisualStudio\14.0_Config\DataSources

Check also keys ...\VisualStudio\12.0_Config\DataProviders, ...\VisualStudio\14.0_Config\DataProviders

It should be no problem to copy some entries from old Visual Studio to new version.
