 This sample shows a minimal implementation for a generic Common Data Service virtual entity data provider plug-in, **DropboxRetrieveMultiplePlugin**, for the [Dropbox](https://www.dropbox.com/) file-sharing service. It uses the "bare metal" approach, translating the <xref:Microsoft.Xrm.Sdk.Query.QueryExpression> through the creation of the custom visitor class, **DropBoxExpressionVisitor**. It returns a collection of the files that satisfy the search criteria as an <xref:Microsoft.Xrm.Sdk.EntityCollection>. 
 
+> [!NOTE]
+> This sample requires the use of ILMERGE to combine the plug-in and Dropbox assemblies prior to registering the assembly with Common Data Service. Use of ILMERGE is not officially supported. A future update to this sample will remove the need to use ILMERGE.

 ## Getting started
 
 In order to build this sample, you must first install the [Dropbox.Api](https://www.nuget.org/packages/Dropbox.Api/) and [Microsoft.CrmSdk.Data](https://www.nuget.org/packages/Microsoft.CrmSdk.Data/) NuGet packages in your solution.  You'll also need a DropBox account and pass a real access token when creating an instance of the **DropboxClient**.
