In our previous post we announced a GitHub example that demonstrates how to develop a .NET MAUI mobile app with the DevExpress Web API Service alongside Entity Framework Core (EF Core) for the backend. This example follows a series of video tutorials dedicated to our 1-Click solution to build CRUD REST API for many popular usage scenarios (powered by the EF Core and XPO ORM).
Introduction to the DevExpress Web API Service
If you reviewed our .NET MAUI example, you know that you can use our Web API Service to create a secure multipurpose OData backend within minutes and you can consume this backend from virtually any frontend technology of your choice. The recent series of posts on how to consume the Web API from JavaScript with Svelte serves as another great example:
If you are not yet familiar with our Web API Service, please see the following posts to get started: Common Questions about the New DevExpress Web API Service (powered by Entity Framework and XPO ORM) | Introduction blog post

Blazor WebAssembly Example Overview
Today we published a new GitHub example: How to Create a Web API Service Backend for a .NET MAUI Application. In this example, we implemented a full client-side Blazor WebAssembly frontend (powered by our Blazor UI component suite). As with the .NET MAUI example, we used our free Web API Service on the backend to take advantage of its many features (auto-generated OData endpoints as well as custom endpoints, authentication and access permissions). We also configured both the backend and the frontend to make use of cookie-based authentication to protect user data.

Just like the .NET MAUI example, our Blazor WebAssembly example also demonstrates how to generate reports and serve them through an API endpoint (please note that the reporting platform is not free – you need to purchase the appropriate DevExpress Subscription to use these features).

To replicate our solution in your next Blazor WebAssembly project, please follow the step-by-step GitHub readme file and remember to:
- First ensure that your development environment is configured as described in the Prerequisites section of the readme file.
- Run the WebApi project and once it starts, launch the Blazor.WebAssembly application.
Your Feedback Matters!
Please take a moment to reply to the following questions – your feedback will help us shape/define future development strategies.

Yes
No
Your experience with it (if any):
2. Are you planning to use our Web API Service for future projects? *
Yes
No
Please elaborate on your reasons: what you like and what you don't, which alternative solutions you already use, what's your experience with them, etc.
3. In addition to basic CRUD and Authorization, which of the following scenarios are of most value to you for API services and why?
Log history of data changes in databases using service endpoints (aka Audit Trail)
Download PDF from report templates and filtered data in databases using service endpoints (aka Reports)
gRPC
