I need my existing cloud-hosted application brought up to date. The codebase is currently on .NET 6 and must be cleanly converted to .NET 10 while keeping every feature intact. The focus is entirely on the back-end: business logic, API layers and the database integration that connects to Azure SQL. Along the way, any NuGet dependencies that block the version jump need to be replaced or upgraded, and build pipelines in Azure DevOps adjusted so the new build targets compile and release without manual tweaks. Once the code compiles on .NET 10, it has to be redeployed to my Azure environment behind Azure Bastion. A successful hand-off means: • the application runs in the new runtime without warnings or breaking changes • database migrations (EF Core) run automatically on first deploy • all existing API endpoints return the same payloads as before • the app is reachable through the current Bastion set-up and passes a smoke test I will supply Please work in a private fork of my repo, open a pull request when the upgrade is stable, and document any code sections you had to refactor so I can review them quickly.

Hello, I am an experienced and professional .NET engineer. I can migrate your cloud-hosted application from .NET 6 to .NET 10 cleanly while keeping every feature, API contract and Azure SQL integration intact. I will focus on the back-end — business logic, API layers and EF Core data access — identifying and upgrading or replacing any NuGet dependencies that block the version jump, documenting each one. I will update the Azure DevOps build pipelines so the new build targets compile and release automatically without manual tweaks. I will configure EF Core migrations to run automatically on first deploy and verify every existing API endpoint returns the same payloads with no breaking changes. I will redeploy to your Azure environment behind the existing Azure Bastion setup and validate the application passes your smoke test. I will work in a private fork, open a clean pull request when the upgrade is stable, and document every refactored section for quick review. I have done similar .NET version migrations and Azure DevOps pipeline updates in recent projects. Please click on my username to check my profile and past .NET work. Let's discuss in details via chat. Thanks

Your EF Core migrations will fail silently if you upgrade to .NET 10 without updating the provider package to match Azure SQL's connection resiliency settings. I've seen this break production deploys when the migration runs but doesn't commit schema changes. Quick question - are you using any third-party NuGet packages that haven't released .NET 10-compatible versions yet? And does your Azure DevOps pipeline currently run integration tests against a staging SQL instance, or are you deploying straight to prod? Here's the upgrade path: - .NET 10 MIGRATION: Retarget the project file, update EF Core to 10.x, and replace deprecated middleware (IHostingEnvironment → IWebHostEnvironment) to eliminate runtime warnings. - NUGET DEPENDENCY AUDIT: Run dotnet list package --vulnerable and dotnet list package --deprecated to flag blockers, then swap or patch incompatible libraries before the build breaks. - AZURE DEVOPS PIPELINE: Modify the YAML to use the .NET 10 SDK, update the publish task to target the new runtime identifier, and add a post-deploy health check that hits /health before marking the release green. - AZURE SQL + EF CORE: Configure connection resiliency with EnableRetryOnFailure and test that migrations apply idempotently so redeployments don't throw duplicate key errors. - BASTION SMOKE TEST: Deploy to staging behind Bastion first, verify all endpoints return 200s with unchanged JSON schemas, then promote to prod only after your test suite passes. I've migrated 8 .NET apps from 6 to 8/9 for clients running Azure App Service and SQL Managed Instance. Let's do a 20-minute call to walk through your current pipeline config and any custom middleware that might need refactoring.

Hello there, We will migrate your .NET 6 codebase to .NET 10, upgrade all blocking NuGet packages, and redeploy to your Azure environment behind Bastion. For EF Core migrations, we will validate schema parity against Azure SQL before the first deploy. This catches silent breaking changes early. A couple of quick things to confirm: 1) Are your Azure DevOps pipelines YAML or classic release definitions? 2) Does the app use any deprecated middleware or authentication libraries? The number quoted here is a starting estimate. The exact cost and timeline will be confirmed after we go through the full scope together. Looking forward to discussing further. Best regards, Faizan

Hi, there. I understand you need an existing .NET 6 application upgraded to .NET 10 while preserving all current functionality, API behavior, database integration, and Azure deployment workflows. I have experience working with ASP.NET Core applications, Azure-hosted environments, Azure DevOps pipelines, EF Core migrations, Azure SQL, and framework upgrade projects involving dependency modernization and compatibility validation. Similar work has included upgrading enterprise applications across major .NET versions, resolving NuGet package conflicts, updating CI/CD pipelines, and ensuring backward compatibility for production APIs. My approach would begin with a full dependency and codebase assessment to identify breaking changes and unsupported packages. I would then upgrade the solution, validate business logic and API layers, update EF Core components, and adjust Azure DevOps build and release pipelines to target the new runtime. After deployment to your Azure environment, I would verify database migrations, execute smoke tests against existing endpoints, confirm payload consistency, and document all refactored areas for transparent review. I am comfortable working through a private fork, maintaining clean commits, and delivering a well-documented pull request that makes the upgrade process easy to audit and approve. Thanks.

⭐Hi there Let's set interview schedule if you want discuss for ur project more detail Your .NET 6 app needs a clean .NET 10 upgrade without breaking API contracts, EF Core migrations, Azure SQL connectivity, or the current Bastion deployment flow. I recently upgraded a production C# backend across multiple runtime versions, replaced blocked NuGet packages, fixed deprecated APIs, and restored CI/CD so all existing endpoints passed regression tests with zero payload changes. I’ll first baseline the current build, API responses, DB schema, and Azure DevOps YAML, then upgrade the SDK, EF Core, NuGet refs, DI config, auth middleware, and SQL provider in controlled commits. To avoid a build that compiles locally but fails in Azure, I’ll validate pipeline agents, runtime hosting bundles, migration execution, env vars, RBAC, Key Vault refs, and deployment access through Bastion. You’ll receive a private fork, clean PR, refactor notes, and smoke-test results for fast review. Is your Azure target App Service, VM, or AKS behind Bastion?
