An image file in a folder	\\Machine\SharedFolder\Imagery.tif
A .lyrx or .lpkx file	\\Machine\SharedFolder\Fires.lyrx
A map service layer	http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer

Example

Create layer with create-params

var flyrCreatnParam = new FeatureLayerCreationParams(new Uri(@"c:\data\world.gdb\cities"))
{
  Name = "World Cities",
  IsVisible = false,
  MinimumScale = 1000000,
  MaximumScale = 5000,
  // At 2.x - DefinitionFilter = new CIMDefinitionFilter()
  //{
  //  DefinitionExpression = "Population > 100000",
  //  Name = "More than 100k"
  //},
  DefinitionQuery = new DefinitionQuery(whereClause: "Population > 100000", name: "More than 100k"),
  RendererDefinition = new SimpleRendererDefinition()
  {
    SymbolTemplate = SymbolFactory.Instance.ConstructPointSymbol(
      CIMColor.CreateRGBColor(255, 0, 0), 8, SimpleMarkerStyle.Hexagon).MakeSymbolReference()
  }
};

var featureLayer = LayerFactory.Instance.CreateLayer<FeatureLayer>(
  flyrCreatnParam, map);

Create FeatureLayer and set to not display in Map.

//The catalog path of the feature layer to add to the map
var featureClassUriVisibility = new Uri(@"C:\Data\Admin\AdminData.gdb\USA\cities");
//Define the Feature Layer's parameters.
var layerParamsVisibility = new FeatureLayerCreationParams(featureClassUriVisibility)
{
  //Set visibility
  IsVisible = false,
};
//Create the layer with the feature layer parameters and add it to the active map
var createdFC = LayerFactory.Instance.CreateLayer<FeatureLayer>(layerParamsVisibility, MapView.Active.Map);

Create Stream Layer with URI

//Must be on the QueuedTask
var url = "https://geoeventsample1.esri.com:6443/arcgis/rest/services/AirportTraffics/StreamServer";
var createParam = new FeatureLayerCreationParams(new Uri(url))
{
  IsVisible = false //turned off by default
};
var streamLayer = LayerFactory.Instance.CreateLayer<StreamLayer>(createParam, map);

//or use "original" create layer (will be visible by default)
Uri uri = new Uri(url);
streamLayer = LayerFactory.Instance.CreateLayer(uri, map) as StreamLayer;
streamLayer.SetVisibility(false);//turn off
