I am looking at this link where we can get all featureclasses, tables or featuredatasets from a geodatabase. I would like to do the same with a File system datastore. Task is to delete all empty feature classes saved in file system datastore.

Currently I have code that loops through all the files in the directory with shape file extensions and use open dataset to check the count and then delete the files. 

Is there a way to Obtain List of Defintions from File system datastore ?

Uma's solution will work for file geodatabases.  For shape files, we don't yet provide this functionality.  I've added it to our backlog for a future release.  In the meantime, your existing algorithm of looping through files in the directory with the .shp extension is your best bet.

Can you try getting the definitions of feature classes using the FileGeodatabase? Will that work for you?

Like this:

public async Task ObtainingDefinitionsFromGeodatabase(){
  await ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() => {
     using (Geodatabase geodatabase = new Geodatabase(new FileGeodatabaseConnectionPath(new Uri(@"C:\Data\Admin\AdminData.gdb")))){
     IReadOnlyList<FeatureClassDefinition> fileGDBDefinitions = geodatabase.GetDefinitions<FeatureClassDefinition>();

     IReadOnlyList<FeatureDatasetDefinition> featureDatasetDefinitions = geodatabase.GetDefinitions<FeatureDatasetDefinition>();
     IReadOnlyList<FeatureClassDefinition> featureClassDefinitions = geodatabase.GetDefinitions<FeatureClassDefinition>();

     }
   });

Uma Harano‌ Thanks Uma. I have pretty much same code for Geodatabase and I was looking for retrieving shapefile from a folder. Thanks Rich Ruh‌ for confirming that and considering it future releases.
