Windows Application Development

A focused Windows desktop app with core functionality typically takes 10-16 weeks. Medium-complexity enterprise apps with database integration, Azure connectivity, and authentication take 16-24 weeks. Complex line-of-business applications with extensive workflows may take 24+ weeks. We provide a detailed timeline after analyzing your business requirements and integration needs.

WinUI 3 is Microsoft's latest native UI framework for Windows desktop apps — it delivers modern Fluent Design, full .NET integration, and first-class Windows 11 support. WPF is the mature, battle-tested framework powering thousands of enterprise apps. UWP targets the Microsoft Store with sandboxed, secure apps. We help you choose the right framework based on your deployment targets, UI requirements, and enterprise infrastructure.

Yes, Windows app modernization is one of our core services. We perform staged migration — refactoring business logic into .NET Standard libraries that both old and new UIs can share, then incrementally rebuilding the UI layer with WinUI 3. The existing application remains fully functional throughout the migration, ensuring zero business disruption.

We support multiple deployment strategies. For Microsoft Store distribution, we handle store listing optimization and staged rollouts. For enterprise deployment, we create MSIX packages compatible with Microsoft Intune, System Center, and group policy deployment. We also support sideloading with code signing certificates and can build custom installers when needed.

Absolutely — Microsoft ecosystem integration is one of our strongest capabilities. We integrate with Azure Active Directory for SSO, Microsoft Graph API for 365 data access, Teams for collaboration features, SharePoint for document management, Power BI for embedded analytics, and Dynamics 365 for CRM/ERP connectivity. Your Windows app becomes a natural hub for your Microsoft-powered workflows.

We implement data virtualization patterns that load only visible records, use async/await throughout to keep the UI thread responsive, leverage compiled bindings in WinUI 3 for faster data display, optimize Entity Framework queries, and implement background data loading with progress indicators. We test with production-scale datasets to guarantee smooth performance regardless of data volume.

Yes, many enterprise environments require reliable offline functionality. We build Windows apps with local SQLite or LiteDB storage that syncs with Azure or SQL Server when connectivity is available. Our offline architecture handles conflict resolution, sync scheduling, and data merging transparently so your teams stay productive in any network condition.

We build and test for Windows on ARM (ARM64) compatibility using the latest .NET versions with native ARM64 support. Our apps run natively on devices like Surface Pro X and Surface Pro 9 5G without x86 emulation overhead, delivering the performance and battery life that ARM64 Windows users expect.

We implement defense-in-depth security: Azure AD authentication with conditional access policies, role-based authorization, Windows Hello biometric integration, data encryption at rest (DPAPI) and in transit (TLS 1.3), secure credential storage via Windows Credential Manager, and application signing with code signing certificates. Security is architected from day one, not bolted on after development.

Yes, we offer ongoing maintenance plans that include Windows OS compatibility updates, .NET version upgrades, security patch management, performance monitoring, bug fixes, and minor feature enhancements. Our support packages ensure your Windows application remains secure, current, and aligned with Microsoft's evolving platform without requiring a full development team.

For cross-platform needs, we can build with .NET MAUI which targets Windows, macOS, iOS, and Android from a shared C# codebase. However, for maximum Windows-native performance and the deepest Microsoft ecosystem integration, we typically recommend native WinUI 3 for the Windows client with shared .NET business logic that can power additional platform clients via API.

Yes, we start every Windows project with a free, no-obligation consultation. We discuss your business requirements, analyze your existing Microsoft infrastructure, evaluate build-vs-buy decisions, explore architecture options, and outline potential approaches. For complex enterprise projects, we can provide a proof-of-concept prototype to validate technical feasibility before full commitment.
