GeoBlazor

Relationship queries in GeoBlazor let you traverse feature layer relationships without leaving C#. Click a feature, query its ObjectIds, then use RelationshipQuery to pull related records. The API handles all the complexity - you just work with strongly-typed .NET objects. 🎯 #Blazor #dotnet #GIS

GeoBlazor Samples This sample demonstrates how to style feature layer with 2D Web Style Symbols using UniqueValueRenderer in 2D MapView.

WebStyleSymbol in GeoBlazor = access to Esri's entire 2D symbol collection from pure C#/Blazor markup. Pair it with UniqueValueRenderer + conditional logic to auto-style features by category. 25+ symbols, zero image files to manage. Sample code: samples.geoblazor.com/web-style-sy... #Blazor #GIS

Excellent tutorial alert! 🚗 @timpurdum.dev walks through building a complete navigation app with GeoBlazor—geocoding, routing, directions, the works. Great example of enterprise GIS capabilities in pure C#/Blazor.

GeoBlazor Samples The sample KML Layer uses a URL to see major earthquakes for latest 30 days from USGS to the map database

KML feeds → Blazor maps, the .NET way 🗺️
Just point GeoBlazor's KMLLayer at any public URL (USGS earthquakes, weather data, whatever). Add it in markup or inject it at runtime with C# code. Full type safety, no JS interop headaches.

Big shoutout to our colleagues at dymaptic for launching Accessible Map Agent! AI-generated alt text for ArcGIS maps in seconds. This is exactly what the #GeoBlazor community needs—making accessibility achievable without the manual grind. Smart solution to a real dev pain point.

GeoBlazor 4.4.0 drops with exception callbacks for MapView/AuthManager, real-time measurement widget events, Bookmarks edit handlers, and RTL support. Plus API cleanup: consolidated elevation types, better namespaces. Solid foundation work for production apps. #Blazor #dotnet #webdev #GIS

GeoBlazor - Enterprise GIS Mapping Components for .NET Native Blazor components for building interactive maps and GIS applications in .NET. Integrate the full power of ArcGIS into your Blazor applications without JavaScript.

The new GeoBlazor website is live with a great addition: actual customer project ideas and implementations! Perfect if you're exploring what's possible with .NET mapping or need some architectural inspiration. Check it out: www.geoblazor.com #Blazor #dotnet #WebDev #GIS

GeoBlazor Pro teams: license management is now fully self-service. Admins can invite team members via email, see registration status in real-time, and assign/reassign Pro licenses without waiting on support. Finally, enterprise GIS licensing that moves at dev speed. #Blazor #dotnet #GIS

GeoBlazor = complete ArcGIS Maps SDK for JavaScript, but you code it all in C#/Blazor. Only .NET library that gives you full enterprise GIS—not just pins on a map. Spatial queries, feature layers, geocoding, the works. No JS required! #Blazor #dotnet #GIS #webdev #ArcGIS

Just wrapped Live! 360 in Orlando - huge thanks to everyone who came by to talk GeoBlazor! The .NET community's interest in building enterprise maps without touching JavaScript was off the charts. Excited to see your projects come to life! #Blazor #dotnet #GIS #webdev #Live360

@timpurdum.dev is speaking today at Live! 360 on Blazor state management patterns. Critical stuff for anyone building complex Blazor apps (like mapping with GeoBlazor). Component lifecycle, preventing render issues, keeping data clean. Essential dev knowledge. #Blazor #dotnet #webdev #Live360

At Live! 360 today comparing Blazor to React/Angular/Vue for JS developers. Diving into how statically-typed C# + .NET tooling creates full-stack web apps with less friction. Spoiler: it's why we built GeoBlazor - unified type-safe mapping without JS! #Blazor #dotnet #webdev #Live360

VS Live Orlando attendees: the GeoBlazor devs are here Nov 18-19! Come talk about implementing maps, geocoding, spatial queries, and custom visualizations in your Blazor apps. Everything in C#, zero JavaScript required. Let's geek out about mapping!

GeoBlazor support breakdown: Core = community via GitHub/Discord (great for MVP), Pro = enterprise SLAs + priority support (for prod apps that can't wait). Both access same docs & samples. Choose based on your deployment criticality. #Blazor #dotnet #webdev #GIS

CSV files with lat/lon columns? GeoBlazor's CSVLayer component maps them instantly. Declare it in #Blazor markup, set the URL property, add a PopupTemplate and SimpleRenderer, and done. No parsing, no coordinate conversion. Great for sensor data, scientific datasets, or IoT telemetry. #dotnet #GIS

Hot take: mapping libraries shouldn't force you into enterprise licenses just to get started.
GeoBlazor Core = free/OSS with real production features
GeoBlazor Pro = commercial tier only when you need advanced capabilities
Build first, upgrade when it makes sense. #Blazor #dotnet #GIS

Demographic Data Zoom in and click on a city, or use the Search Widget to find a city, and you will see a popup with population data for a 1-mile radius buffer around the selected point.

Query demographic data as easily as querying databases. GeoBlazor's ArcGISRest integration + GeometryEngine lets you pull population stats for any location with just a few lines of C#. Perfect for site analysis, market research, or planning. #Blazor #dotnet #GIS

Day 1: Points: timpurdum.dev/post/2025/11...

Using GeoBlazor on my blog to share food pantry information in the US at this time of insecurity for many.

(Late to post, had to fix an unrelated dotnet 10 bug on my site.)

#dotnet #blazor #gis

Calculate Geometries Use the buttons in the top right to see a demonstration of drawing a buffer around a point, finding the intersection between two graphics, and finding the union of two polygons.

Your #Blazor app needs spatial analysis? Inject #GeometryEngine and you've got geodesic buffers, polygon intersections, unions—all the #GIS operations you need. No JavaScript required, just clean C# with async/await. Real spatial analysis in your .NET stack.
