Getting Started

(from https://docs.geoblazor.com/pages/gettingStarted.html)

  1. Create a new Blazor Web App (.NET 8), Blazor Server, Blazor Wasm, or Blazor Hybrid (MAUI) project, using the templates provided in your IDE or the dotnet CLI.

  2. add a PackageReference to the latest version of the dymaptic.GeoBlazor.Core package via your IDE's Nuget Package Manager or dotnet add package dymaptic.GeoBlazor.Core. For Blazor Web Apps supporting WebAssembly, add this reference to the .Client WebAssembly project.

  3. The ArcGIS API requires some form of authentication. The simplest is to use an API Key. Generate a key from the ArcGIS Developer Dashboard. For Blazor Server, place it in your appsettings.json, like this:

        "ArcGISApiKey": "yourKeyValue"

    <div style="font-size: 0.8rem; font-style: italic; margin-bottom: 1rem;">

    Note: If you are using Blazor WASM, there are several issues with this approach. First, <code>appsettings.json</code> is not added by default to all templates. If you want to add it yourself, you need to add it inside the <code>wwwroot</code> folder. For Blazor Web Apps with WebAssembly, you must define the API key in both projects.

    <span style="color:red;">Be Aware</span> that the API key will be exposed in the browser (just like it would with Javascript). Even when using Blazor Server, the API key may be present in HTTP requests visible to the user in the browsers dev tools, so you should probably take other steps like <a href="https://developers.arcgis.com/documentation/mapping-apis-and-services/security/api-keys/#referrers" target="_blank"> setting up referrer rules in ArcGIS</a>. </div> <div style="font-size: 0.8rem; font-style: italic"> You can also set up an OAuth2 workflow, which is more secure as it does not expose a static API key, but this is more complex. You can read about all the authentication options in <a href="https://docs.geoblazor.com/pages/authentication.html">Authentication</a>. </div>

  4. In the root file that defines your html, add the following lines to the <head> section. This would be _Layout.cshtml for Blazor Server, index.html for Blazor Wasm and Blazor Hybrid, or App.razor for Blazor Web Apps. Note that YourProject is the namespace for the application that you are creating.

    <link href="_content/dymaptic.GeoBlazor.Core"/>
    <link href="_content/dymaptic.GeoBlazor.Core/assets/esri/themes/light/main.css" rel="stylesheet" />
    <link href="YourProject.styles.css" rel="stylesheet" />

    or (dark theme)

    <link href="_content/dymaptic.GeoBlazor.Core"/>
    <link href="_content/dymaptic.GeoBlazor.Core/assets/esri/themes/dark/main.css" rel="stylesheet" />
    <link href="YourProject.styles.css" rel="stylesheet" />

    <div style="font-size: 0.8rem; font-style: italic; margin-bottom: 1rem;"> Note: You may already have the YourProject.styles.css file. If so, you can just add the two lines to the existing file. In some .Net templates, this file is commented out by default and you will need to add it. </div>

  5. In _Imports.razor (for each executable project), add the following lines, or add as needed to resolve code that you consume.

    @using dymaptic.GeoBlazor.Core.Components
    @using dymaptic.GeoBlazor.Core.Components.Geometries
    @using dymaptic.GeoBlazor.Core.Components.Layers
    @using dymaptic.GeoBlazor.Core.Components.Popups
    @using dymaptic.GeoBlazor.Core.Components.Symbols
    @using dymaptic.GeoBlazor.Core.Components.Views
    @using dymaptic.GeoBlazor.Core.Components.Widgets
    @using dymaptic.GeoBlazor.Core.Events
    @using dymaptic.GeoBlazor.Core.Objects
  6. In Program.cs (for each executable project), add the following line to your builder.Services to inject logic components like GeometryEngine.


    If you are using Blazor Server or InteractiveServer mode in Blazor Web Apps, you should also add the following lines to Program.cs to support the .wsv file type.

    var provider = new FileExtensionContentTypeProvider();
    provider.Mappings[".wsv"] = "application/octet-stream";
    // NOTE: for some reason, you still need the plain "UseStaticFiles" call above
    app.UseStaticFiles(new StaticFileOptions
        ContentTypeProvider = provider
  7. Create a new Razor Component in the Pages folder, or just use Index.razor. Add a MapView. Give it basic

  8. Create a new Razor Component in the Pages folder, or just use Index.razor. Add a MapView. Give it basic parameters to ensure that it can render.

    @page "/"
    <MapView Longitude="_longitude" Latitude="_latitude" Zoom="11" Style="height: 400px; width: 100%;"> 
    @code {
       private readonly double _latitude = 34.027;
       private readonly double _longitude = -118.805;
  9. Within the MapView, define a map using the WebMap component. To load a pre-generated map from ArcGIS Online or Portal, get the Map Id (PortalItem Id) of the map.

    <MapView Longitude="_longitude" Latitude="_latitude" Zoom="11" Style="height: 400px; width: 100%;"> 
            <PortalItem Id="4a6cb60ebbe3483a805999d481c2daa5" />
  10. Add a Widget to the MapView, after the WebMap.

<MapView Longitude="_longitude" Latitude="_latitude" Zoom="11" Style="height: 400px; width: 100%;"> 
        <PortalItem Id="4a6cb60ebbe3483a805999d481c2daa5" />
    <ScaleBarWidget Position="OverlayPosition.BottomLeft" />
  1. Run your application and make sure you can see your map!
  2. Now that you have a great starting point, you can now start to customize the features available in your new app using Geoblazor's capabilites:<br/> -Take a look at the Documentation pages to learn more.
  3. Optional: To remove the Thank You message from your console messages, please consider registering your application on the dymaptic licensing server. After registering and filling out a small questionnaire, you will receive a registration key, which you can add to any configuration (e.g., appsettings.json) to remove the message.
