- .NET Core Development Company in Houston
DESSS is a .NET Core development company in Houston. Our ASP.NET Core development services in Houston cover new web applications, APIs, Blazor front ends, background services and integrations with the systems you already run.
.NET Core, now simply called .NET, is Microsoft’s open-source, cross-platform successor to the .NET Framework. Custom .NET Core development in Houston suits organizations that work in the Microsoft ecosystem, need strong performance and security, and want long-term support for their applications.
Our developers work from our Houston headquarters, with an office in Austin. If you are deciding how to modernize an existing .NET Framework application first, our .NET Core consulting team can assess it before any code is written.
What we build
ASP.NET Core web applications, REST and gRPC APIs, Blazor front ends and worker services.
Current versions
New work starts on .NET 10, the long-term support release published in November 2025.
Hosting
Azure App Service, containers, Linux servers or your own Windows and IIS infrastructure.
Where we work
Houston headquarters and an Austin office, serving clients across Texas and the United States.
WHAT WE BUILD
ASP.NET Core development services in Houston
Most .NET Core development work falls into six categories. Larger projects usually combine several.
Web applications
Business applications with ASP.NET Core MVC or Razor Pages, role-based security and audit logging.
APIs and microservices
REST, gRPC and real-time SignalR services that other systems and apps can rely on.
Blazor front ends
Interactive web interfaces written in C#, sharing code and validation with the back end.
Background services
Scheduled jobs, queue processors and integration workers built as .NET worker services.
Integrations
Connections to ERP, CRM, Microsoft 365, payment and shipping systems through their APIs.
Upgrades and support
Keeping applications on supported .NET releases, with fixes and new features over time.
.NET TECHNOLOGY
The .NET technology behind our builds
We pick the parts of the .NET platform that fit each project. These are the ones we use most.
ASP.NET Core web apps
What is ASP.NET Core? ASP.NET Core is the web framework in modern .NET. It runs on Windows, Linux and containers and supports MVC, Razor Pages and Minimal APIs, with built-in dependency injection, configuration and logging.
–MVC and Razor Pages
–Minimal APIs
–Built-in dependency injection
–Health checks and logging
Blazor front ends
When do we use Blazor? Blazor lets teams build interactive web interfaces in C# instead of JavaScript. It suits internal business applications where sharing models and validation between front end and back end saves time.
–Server and WebAssembly rendering
–Shared C# models
–Reusable components
–Works alongside JavaScript libraries
Data access
How do .NET applications store data? We use Entity Framework Core for most data access, with SQL Server, Azure SQL or PostgreSQL, and Dapper where raw query performance matters.
–Entity Framework Core
–SQL Server and Azure SQL
–PostgreSQL
–Caching with Redis
Identity and security
How are users signed in? For business applications we usually integrate with Microsoft Entra ID or another OpenID Connect provider, so staff use their existing accounts with MFA and Conditional Access.
See our Microsoft Entra Conditional Access and MFA service.
–Microsoft Entra ID sign-in
–OpenID Connect and OAuth 2.0
–Role and policy-based authorization
–Secrets in Azure Key Vault
Deployment and hosting
Where can .NET applications run? Modern .NET runs on Azure App Service, containers on Azure or AWS, Linux servers, or Windows servers with IIS. We set up automated pipelines so every release is built, tested and deployed the same way.
–Azure App Service
–Docker containers
–IIS on Windows Server
–CI/CD with Azure DevOps or GitHub Actions
HOW WE WORK
How a .NET Core development project runs
Six steps take a .NET project from first conversation to a supported application.
STEP 01
Discovery
We map users, workflows, data and integrations, and agree the scope of the first release.
STEP 02
Architecture
We design the solution structure, data model, identity approach and hosting.
STEP 03
Build in sprints
Short sprints with demos every two weeks, so you see progress early.
STEP 04
Test and secure
Unit and integration tests, code review and a security check before release.
STEP 05
Deploy
Automated deployment to Azure or your servers, with monitoring in place on day one.
STEP 06
Support
Fixes, .NET version upgrades and new features as your needs change.

A .NET Core development company builds and maintains applications on Microsoft’s modern .NET platform. DESSS builds ASP.NET Core web applications, APIs, Blazor front ends and background services for Houston businesses.
.NET Framework is the original Windows-only platform, now in maintenance mode at version 4.8.1. .NET Core, renamed simply .NET from version 5, is open source, cross-platform and receives new features every year.
Start on the current long-term support release. That is .NET 10, released in November 2025 and supported for three years. .NET 8 support ends in November 2026.
Yes. ASP.NET Core is fast, secure by design, well documented and integrates naturally with SQL Server, Azure and Microsoft Entra ID, which suits most business applications.
Yes. Modern .NET runs on Windows Server with IIS, on Linux, or in containers, as well as on Azure. We set up the hosting that fits your infrastructure.
Yes. Our .NET Core consulting team assesses the application and plans the migration, and our developers carry it out.
