@PreetiMaske Thank you for the information. I have read through the links that you provided and think im still a little confused. A simplified idea of what I'm wanting to do is that i have a map and if i were to click on that map then it would call a method and add one of those mil2525d symbols to that point of the map. To do this would I use the dictionary renderer? Cause to me it seemed that the dictionary renderer already contained the data of what symbols would be used and where they go on the map. My desktop app needs to be more dynamic. Allowing individual symbols to be displayed and removed during runtime. ... View more

@JayantaPoddar That is what I assumed. Is it possible to install previous versions of ArcGIS, say V.100.7? I saw that if you link your account with your organization than it will allow you to install previous versions. However, I'm not with any organization and just need access to version 100.7 ...

@LukeSmallwood  So I'm occasionally getting an error with my ExportVectorTiles. Depending one where I try to export from I will get an error like this...     namespace ArcGISRuntime.WPF.Samples.ExportTiles { public partial class ExportTiles { // URL to the service tiles will be exported from. private Uri _serviceUri = new Uri("https://basemaps.arcgis.com/arcgis/rest/services/World_Basemap_Export_v2/VectorTileServer"); public ExportTiles() { InitializeComponent(); // Call a function to set up the map. Initialize(); } private async void Initialize() { try { // Create the tile layer. ArcGISVectorTiledLayer myLayer = new ArcGISVectorTiledLayer(_serviceUri); // Load the layer. await myLayer.LoadAsync(); // Create the basemap with the layer. Map myMap = new Map(new Basemap(myLayer)) { // Set the min and max scale - export task fails if the scale is too big or small. MaxScale = 5000000, MinScale = 10000000 }; // Assign the map to the mapview.

@LukeSmallwood okay that makes a lot more sense. Thanks for all of your explanations. I know it is probably very similar, but is there an example provided for using the ExportVectorTiles? ... View more

@LukeSmallwood I used that sample you shared a link to for ExportTileCache. It uses the default World_Street_Map and contains a link to it. I have tread looking around and different URL's, but I'm not sure hw to export different maps (like world topographic). The AGOL link shows me a bunch of different maps available for export but I'm not sure where to go/what URL to use for those maps in the program in order to export them. ... View more

@LukeSmallwood Thanks for sharing that info. It looks like they offer a lot of ways to download a basemap for use offline, but as i have been looking around it looks like that most the time these offline maps remain on the local server. Is there a way to possibly download the basemap directly to the local file system of the computer? The AGOL group link you attached had many maps available for export but it seemed they were for export to other Esri/ArcGIS products like ArcGIS pro rather than being able to download them as a tile or raster file. Is it possible to do this? ... View more

@JoeHershman  That is what my MainWindow.xaml looks like. <Window x:Class="map_display.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:local="clr-namespace:map_display" xmlns:esri="http://schemas.esri.com/arcgis/runtime/2013" mc:Ignorable="d" Title="MainWindow" Height="450" Width="800"> <Window.Resources> <local:MapViewModel x:Key="MapViewModel" /> </Window.Resources> <Grid> <esri:MapView x:Name="MainMapView" Map="{Binding Map, Source={StaticResource MapViewModel}}" GraphicsOverlays="{Binding GraphicsOverlays, Source={StaticResource MapViewModel}}" MouseLeftButtonUp ="MainMapView_MouseLeftButtonUp" /> </Grid> </Window>   ...
