WPF Development Servicesfor Windows Apps That Can't Fail.
Trading floors, hospital systems, manufacturing dashboards — the places WPF still runs are the places downtime isn't an option. Our WPF development services cover new enterprise builds, .NET Framework to .NET 10 modernization, and cross-platform migration for the rare case where Windows-only genuinely stops making sense.

- MVVM strict

Why Entalogics for WPF
Four problems every
inherited WPF codebase
has.
WPF itself is stable. What we inherit usually isn't — code-behind running to 3,000 lines, no ViewModel layer, and a .NET Framework version Microsoft stopped patching years ago.
Performance01
Nobody virtualized the big list, so it just got slower.
A 10,000-row DataGrid without virtualization can spike past 2GB of memory. VirtualizingStackPanel and proper CollectionView usage fix this before users notice.
Architecture02
MVVM existed in name, not in practice.
ViewModels owned nothing, code-behind owned everything. We enforce real boundaries — logic and state in the ViewModel, layout in the View, services behind interfaces with DI.
State03
Binding failures were invisible by default.
A misspelled property name in XAML just renders blank — WPF won't tell you. We enable binding error tracing and enforce compiled bindings so a typo shows up in debug, not in a user's bug report.
Type safety04
Strings did the job types should have done.
Magic strings in XAML bindings, no design-time DataContext, no compile-time check on a renamed property. We wire strong typing through every layer so a rename breaks the build, not the UI.
When WPF, when not
WPF is a tool,
not a legacy sentence.
Microsoft ships updates but no major new features — WPF is in maintenance mode. That's the wrong fit for some projects and exactly right for others. We'll tell you which one is true for yours.
STAY ON WPF WHEN
- Windows-only is permanent — your users and your IT estate aren't going anywhere
- The existing codebase works — modernizing to .NET 10 with the Fluent theme costs a fraction of a rewrite
- Data-heavy UI is the product — grids, charts, real-time dashboards where WPF's rendering still wins
- DevExpress, Telerik, or Syncfusion are already deeply embedded and working
CONSIDER MIGRATION WHEN
- Cross-platform is a genuine requirement — Mac, Linux, or mobile users need the same app
- Hiring is the bottleneck — XAML developers are a much smaller pool than web developers
- .NET Framework lock-in is blocking security patches or CI/CD modernization
WE SAY NO WHEN
- "Rewrite it because WPF is old" — if it works, modernize it, don't rewrite for fashion
- "WPF for a new consumer app" — the hiring pool and framework trajectory don't justify it
- "Migrate to MAUI in three weeks" — that's not a migration, that's a disaster in progress

The playbook
WPF development patterns
we ship on repeat.
Patterns from real enterprise WPF applications — not MVVM blog posts.
P01
MVVM Toolkit plus DI.
CommunityToolkit.Mvvm for ObservableObject and RelayCommand, DI for service registration. Testable from day one, no framework lock-in.
P02
Compiled bindings wherever possible.
Design-time DataContext enforced, binding failure tracing on. A silent binding error is treated as a bug, not ignored.
P03
Virtualization on every large list.
VirtualizingStackPanel on any ItemsControl over 50 items, container recycling on, deferred scrolling on big datasets.
P04
Prism module composition.
Each feature is its own Prism module with its own registration and navigation. Two teams build two features without touching each other's code.
P05
Integration tests on ViewModels.
Real service fakes over mocking everything. FlaUI for critical UI workflows. CI on every PR.
P06
Incremental .NET 10 upgrade.
One project, one assembly at a time. The app stays deployable the entire way through — no flag-day.
Signature case
A trading dashboard,
modernised from .NET Framework 4.8 to .NET 10.
A financial trading platform on WPF .NET Framework 4.8 — 4-second cold start, DataGrid rendering 15,000 rows without virtualisation consuming 1.8GB, no CI/CD pipeline, and manual ClickOnce deployment requiring IT intervention. Upgraded to .NET 10 with Fluent theme, virtualised grids, and Azure DevOps pipeline in 10 weeks. No feature freeze.
Before
.NET Framework 4.8 · cold start 4s · DataGrid 1.8GB at 15K rows · manual deploy · no CI/CD
After
.NET 10 LTS · cold start 1.4s · DataGrid 180MB at 15K rows · Azure DevOps auto-deploy · full CI

FAQ
Questions we get on almost
every WPF call.
Support status, WinForms vs WPF, modernization, upgrades — in roughly the order people ask.Yes. It ships with .NET 10 LTS, supported until 2028, and picked up the Fluent theme in .NET 9. It's in maintenance mode — no major new features — but it's a credible, actively supported path for Windows-only enterprise apps.
WPF, in almost every case. Better scalability, stronger security posture, and a rendering engine built for complex UI. WinForms is simpler to pick up, but that's its only real advantage left.
Modernize if Windows-only is permanent and the codebase is fundamentally sound — upgrading to .NET 10 costs a fraction of a rewrite. Rewrite only if cross-platform is a genuine requirement, and even then Avalonia offers a WPF-like path.
Yes. One project, one assembly at a time. The app stays deployable throughout, with BinaryFormatter removed and the Fluent theme applied incrementally.
Depends on scope and how much legacy code exists. The week-one audit gives us real numbers — you get a fixed quote from that, not a range that grows.
Yes. DevExpress, Telerik, Syncfusion, or fully custom controls — we adapt to what's already there and flag anything that genuinely needs to change.
