Explanation / Answer

For System.data:

Hi you have to add the .dll file of System.Data to your AssetsPlugins folder . To do so, go to your directory UnityEditorDataMonolibmono.0 and get the System.Data file and later add it to the folder mention before

.

For System.Drawing:

You need to add a reference to System.Drawing.dll.

This can be done as follows: In your Solution Explorer (Where all the files are shown with your project), right click the "References" folder and find System.Drawing on the .NET Tab.

For System.Windows.Form:

Expand the project in Solution Tree, right click on References, Add Reference, Select System.Windows.Forms on Framework tab.You need to add reference to some non-default assemblies sometimes
