This topic describes how to use the .NET SDK to query the details of a sample image in a similar image library.
Description
You can call this API to query the details of a sample image. For more information about the parameters, see the Query Sample Image Library Details API reference.
You must use the Content Moderation endpoint to call the service using the SDK. For more information about API endpoints, see Endpoints.
Prerequisites
The .NET dependencies must be installed. For instructions, see Install .NET dependencies.
Note
You must use the required .NET version described in the Installation topic to install the dependencies. Otherwise, subsequent operation calls fail.
