DESSS is a .NET Core consulting company in Houston. Our .NET Core consulting services in Houston help organizations decide whether to upgrade, migrate, refactor or rebuild their .NET applications, and plan the work so the business keeps running.
The most common request is ASP.NET Core migration services in Houston: moving web applications and services from the Windows-only .NET Framework to modern, cross-platform .NET. Some parts move with little change. Others, such as Web Forms pages and WCF services, need a deliberate redesign.
We also review architecture, performance and security for applications already on .NET Core. When the plan is ready, your developers or our .NET Core development team can carry it out.
Most common need
Moving ASP.NET, Web API and WCF applications from .NET Framework to ASP.NET Core.
What you receive
An assessment report, a migration or improvement roadmap, and effort estimates.
Version timeline
.NET 10 is the current long-term support release. .NET 8 support ends in November 2026.
Where we work
From our Houston headquarters, with an office in Austin, for clients across Texas.
CONSULTING SERVICES
.NET Core consulting services in Houston
Six types of .NET consulting cover most of what Houston teams ask for.
Migration assessment
An inventory of projects, dependencies and blockers, with a recommended migration path for each part.
ASP.NET Core migration planning
A staged plan to move ASP.NET MVC, Web Forms, Web API and WCF to ASP.NET Core.
Architecture review
A review of solution structure, layering, data access and integration patterns, with practical improvements.
Performance tuning
Profiling slow requests, memory use and database calls, then fixing the real bottlenecks.
Version upgrades
Planning moves between .NET releases, such as .NET 8 to .NET 10, including breaking changes.
Hosting decisions
Comparing Azure App Service, containers and on-premises IIS for cost, operations and security.
MIGRATION PATHS
ASP.NET Core migration paths
Different parts of a .NET Framework application need different treatment. These are the paths we plan most often.
ASP.NET MVC and Web API
How hard is it to move ASP.NET MVC to ASP.NET Core? MVC and Web API applications usually migrate with moderate effort. Controllers and views carry over in shape, while startup, configuration, dependency injection and middleware are rewritten the ASP.NET Core way.
–Controllers and views adapted
–Startup and configuration rewritten
–Filters become middleware where needed
–Authentication reconfigured
ASP.NET Web Forms
Can Web Forms move to ASP.NET Core? Not directly. Web Forms is not part of ASP.NET Core, so pages are redesigned, usually in Blazor or Razor Pages. We prioritize screens by business value and move them in stages.
–Screen inventory and priority
–Blazor or Razor Pages redesign
–Business logic extracted and reused
–Side-by-side running during migration
WCF services
What happens to WCF services? WCF server support is not part of modern .NET. Services can move to CoreWCF to keep existing clients working, or be redesigned as REST or gRPC APIs when clients can change.
–Client and contract inventory
–CoreWCF for compatibility
–REST or gRPC for new designs
–Contract tests for each endpoint
Data access
Do we have to rewrite data access? Not always. Entity Framework 6 can run on modern .NET, and many teams move to EF Core later. Stored procedures and ADO.NET code usually carry over with minor changes.
–EF6 compatibility check
–EF Core migration where it pays off
–Stored procedure review
–Connection and transaction handling
Incremental migration
Do we have to migrate everything at once? No. Microsoft supports an incremental approach where a new ASP.NET Core application sits in front of the old one and takes over routes one at a time, with shared session and authentication adapters.
For non-.NET legacy systems, see our FoxPro to .NET migration service.
–YARP reverse proxy in front
–System.Web adapters
–Routes moved one area at a time
–Old app retired when empty
HOW WE WORK
How a .NET consulting engagement runs
A migration assessment follows six steps and ends with a plan your team can act on.
STEP 01
Kickoff
We agree the goals, the applications in scope and the people we will talk to.
STEP 02
Inventory
We catalog projects, frameworks, NuGet packages, third-party components and hosting.
STEP 03
Analyze
Automated analysis and manual review identify blockers and the effort for each part.
STEP 04
Choose paths
Each component gets a recommended path: carry over, adapt, redesign or retire.
STEP 05
Roadmap
We sequence the work into stages that keep the application running throughout.
STEP 06
Walkthrough
We present to your team and stay available while the work is carried out.

WHY DESSS
Why choose DESSS for .NET Core consulting
Migration advice is only useful if it reflects what it really takes to deliver.
Consultants who also build
Our consultants work alongside our .NET developers, so estimates reflect real delivery effort.
Migrate without a big bang
We plan staged migrations so the business keeps running while the application moves.
Microsoft ecosystem experience
We also deliver Azure, Microsoft 365, Entra ID and Dynamics work, which simplifies integration decisions.
No lock-in
Your team can carry out the roadmap. We are available for reviews whenever you need them.
DESSS .NET Core consulting includes migration assessments, ASP.NET Core migration planning, architecture and performance reviews, version upgrade planning and hosting advice, delivered as a report and roadmap.
It depends on the size of the application and how much Web Forms or WCF it contains. An assessment gives you a realistic estimate, and staged migrations let you deliver value along the way.
.NET Framework 4.8.1 is still supported as part of Windows, but it receives no new features. New development, libraries and cloud services increasingly target modern .NET.
Not directly, because Web Forms is not part of ASP.NET Core. Pages are redesigned, usually in Blazor or Razor Pages, while business logic is extracted and reused.
They can move to CoreWCF to keep existing clients working, or be redesigned as REST or gRPC APIs. We recommend the path based on who calls each service.
.NET 8 is a long-term support release that reaches end of support in November 2026. Applications on .NET 8 should plan a move to .NET 10, the current long-term support release.
