README .NET datalayer.provider.virtual¶

This .NET sample demonstrates how to write a light-weight provider, listing to a wildcard address and managing virtual nodes.

IMPORTANT:

The sample is recommended for large, very large or dynamic sized set of nodes to handle. We are listening just to any wildcarded address ( e.g. myRoot/**) and using self-managed virtual nodes, just returned in OnBrowse() method, which is very efficient.

Please read the Best Practise section in common .NET documentation for more details and recommended samples.

Introduction¶

The sample shows a basic concept for a leight-weight self-managed provider implementation

Description¶
