No separate REST APIs, no WebAssembly sync layers. Just one C# codebase so I can actually ship things fast (<a href="https://youtu.be/V3SQZv04oOo" rel="noopener noreferrer">https://youtu.be/V3SQZv04oOo</a>).</p> <p>To make Blazor Interactive Server survive production without the dreaded circuit crashes, I wired up a global exception boundary to catch and log errors silently. I also used EF Core global query filters to handle multi-tenancy automatically, and decoupled the provider so swapping from SQL Server to Postgres is literally a one-word change in appsettings.json (<a href="https://youtu.be/pdCzeQ7V794" rel="noopener noreferrer">https://youtu.be/pdCzeQ7V794</a>).</p> <p>I attached the architecture map. I want to know if this approach is actually solid for a SaaS foundation, or if I'm missing some massive landmines.</p> <p>I threw a live demo up on a free tier. If anyone wants to poke around, test the UI speed, or try to break the tenant isolation, I’d love some brutal feedback.</p> <p>Demo: <a href="https://cnex.runasp.net/" rel="noopener noreferrer">https://cnex.runasp.net/</a></p> <p>User: <a href="mailto:admin@cnex.com">admin@cnex.com</a></p> <p>Pass: Admin@123<br> <a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F5ed7s57zi691yv4qoxcu.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F5ed7s57zi691yv4qoxcu.png" alt=" " width="800" height="1200"></a></p> csharp blazor webapp saas
