There are a number of tools built into ArcGIS Pro: geoprocessing, networking, and wide number of other analytical tools that give ArcGIS Pro the power to do so many things. Did you know that you can publish these tools to consume in a web app? GeoBlazor harnesses the power of the ArcGIS Maps SDK for JS to connect and bring the capabilities of these tools to your .NET web applications. We will discuss the capabilities and limitations of 'publishing' ArcGIS Pro tools and their usefulness in web applications. We will then demonstrate how GeoBlazor can connect to a published tool with minimal code to create a customized routing capability in a .NET web application.
