GeoBlazor

GeoBlazor Pro is now free and open source! It’s under the MIT license, with its code public right next to Core. Upgrading to 4.7 is a version bump, license keys are optional, and your map renders with or without one. Next up: V5, one free package. www.geoblazor.com/blog/announc... #Blazor #GIS

When telemetry arrives faster than your map can draw it, vehicles start showing up where they used to be. The GeoBlazor fix: keep the latest record per vehicle and batch changed vehicles into one ApplyEdits call per map tick. See it in action: geoblazor.com/blog/keeping... #GeoBlazor #Blazor

GeoBlazor users this one's for you: is a legacy ArcGIS API key lurking in your appsettings.json? Those stop working April 15, 2027. The fix is simple: new API key credentials with the same privileges, then swap the ArcGISApiKey value. 🔗 www.geoblazor.com/blog/legacy-...

🗺️ GeoBlazor 4.6.1 now includes Feature Data Tables! - See the sample: samples.geoblazor.com/feature-tables - Read the full release announcement: geoblazor.com/blog/announc... #blazor #dotnet #csharp #gis #arcgis

#GeoJSON layers in GeoBlazor #blazor #ArcGIS #dotnet #csharp

Ever wanted to drop a live GeoJSON feed onto a Blazor map without touching JavaScript? GeoBlazor's GeoJSONLayer makes it painless. 🌐 New sample uses live USGS earthquake data: magnitude-scaled points, GeoJSON-bound popups, runtime feed-swapping. geoblazor.com/blog/visuali... #blazor #gis #dotnet

What if your ArcGIS map could run natively on desktop, mobile, and the web — from a single .NET codebase? That's what GeoBlazor + @platform.uno makes possible. New tutorial is live 🧵 👉 geoblazor.com/blog/bridgin... #dotnet #Blazor #GIS #geospatial

GeoBlazor Pro licensing clarified: pay per dev seat, deploy anywhere without limits. Dev/test/prod environments? Multiple regions? Customer instances? All covered under your team's license. No runtime fees, no deployment surprises. Details: www.geoblazor.com/blog/geoblaz... #Blazor #dotnet #GIS

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

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. timpurdum.dev/post/2025/12... #Blazor #dotnet #GIS

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. Live demo: samples.geoblazor.com/kmllayers #Blazor #dotnet #webdev

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

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

We're hiring a Marketing Lead / GIS Content Creator! Help us tell the GeoBlazor story and grow our boutique GIS + AI consulting team. Looking for someone who gets geospatial tech, can create killer content, and wants to shape the future of spatial development. #GIS #Hiring

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! #Blazor #dotnet #GIS #VSLive #ArcGIS

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 docs.geoblazor.com/pages/license

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

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 samples.geoblazor.com/demographic-...

#30DayMapChallenge 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

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.

Love how GeoBlazor handles bookmark widgets. Full edit/add/reorder capabilities in pure C#. Set up reactive listeners for bookmark events, apply feature effects on selection, all without leaving .NET. Great for building spatial dashboards. #Blazor #dotnet #GIS samples.geoblazor.com/Bookmarks
