Create a Custom Connector for your Web API from within Visual Studio

I’m excited to announce that Power Platform is now a connected service in Visual Studio 2022 Preview!

Code-first developers will now be able to create both APIs and connectors from within Microsoft Visual Studio, thereby minimizing context switching when developing custom connectors for Microsoft Power Platform.

Let’s explore how to create a simple Power apps canvas app from an ASP.NET Web API project.

Create a new ASP.NET web API.

Add Power Platform as a connected service.

By adding Power Platform as a service dependency, you can update an existing custom connector, or create a new one from your API.

Connected Services

Visual Studio leverages dev tunnels feature to expose your local running API to a public endpoint. It means you can use Power Apps with your API running in your local environment!
