.NET & Custom Development Services
When your business outgrows no-code solutions, Stallions brings enterprise-grade .NET development — deeply integrated with Azure, Dynamics 365, and the Power Platform — to build exactly what you need.
The right framework for
serious business software
Not every project warrants custom code. But when it does, .NET stands apart as Microsoft's flagship development platform — the same framework that powers Azure itself.
When should you choose .NET?
.NET isn't a competitor to low-code platforms like Power Apps — it's the next tier up. Organisations turn to .NET when business requirements exceed what configuration, customisation, or citizen development can handle.
- Your application needs to process millions of transactions or concurrent users, and no-code solutions hit performance walls
- You're building a proprietary product, portal, or SaaS platform that must be entirely bespoke to your business
- You need deep integrations with legacy systems, third-party APIs, or complex business logic that low-code simply can't express
- Security, compliance, and auditability requirements demand full control over code, hosting, and data flow
- Your team requires CI/CD pipelines, automated testing, and DevOps-grade release management
- You're extending Dynamics 365 or Power Platform with custom APIs, middleware, or microservices that sit outside those platforms
Enterprise-Grade Performance
.NET compiles to native code via ahead-of-time compilation, delivering speeds that rival C++ while maintaining developer productivity. ASP.NET consistently leads TechEmpower benchmarks.
Security-First Architecture
Built-in identity management, data protection APIs, anti-forgery tokens, and HTTPS enforcement. .NET gives you full control over every layer of your application's security posture.
Cloud-Native by Design
.NET was rebuilt from the ground up to be cross-platform and cloud-native. Containerised microservices, serverless functions, and Kubernetes orchestration are all first-class citizens.
Full Microsoft Ecosystem Alignment
From Azure Active Directory and SQL Server to Dynamics 365 SDKs and the Power Platform — .NET is the native language of the entire Microsoft stack, ensuring seamless interoperability.
Common Use Cases
What organisations build with .NET
From internal line-of-business applications to public-facing platforms serving millions, .NET handles the full spectrum of enterprise software needs.
Enterprise Web Applications
Intranets, customer portals, case management systems, and multi-tenant SaaS platforms. ASP.NET Core with Blazor or MVC patterns delivers production-grade web applications with full server-side rendering, real-time communication via SignalR, and responsive frontends.
RESTful APIs & Microservices
Building the middleware and service layers that connect your CRM, ERP, line-of-business apps, and third-party services. .NET Minimal APIs and gRPC services offer lightweight, high-throughput communication between distributed components.
Integration & Data Pipelines
ETL processes, real-time event streaming, and orchestrated workflows that move data between Dynamics 365, Azure services, legacy databases, and external APIs. Azure Functions and Durable Functions manage complex, stateful integrations.
Line-of-Business Applications
Bespoke applications for workforce management, fleet tracking, asset management, licensing, and compliance — where commercial off-the-shelf software doesn't fit. Think WPF desktop apps, cross-platform MAUI apps, or hybrid web-mobile solutions.
AI & Machine Learning Services
ML.NET for in-app predictions, Azure Cognitive Services integration, and custom AI models deployed as .NET APIs. From document intelligence and natural language processing to predictive analytics baked directly into your business workflows.
Background Processing & Automation
Worker services, scheduled jobs, and event-driven automation that runs reliably behind the scenes. From nightly data reconciliation to real-time notification engines, .NET's hosting model supports long-running, resilient background processes.
.NET + Azure
Where .NET and Azure become one platform
Azure was built with .NET, and .NET was rebuilt for Azure. This isn't a bolt-on compatibility — it's a deeply integrated engineering relationship where each platform amplifies the other.
Azure App Service & Container Apps
Deploy .NET applications directly from Visual Studio or CI/CD pipelines to fully managed hosting. Auto-scaling, deployment slots for blue-green releases, and built-in monitoring through Application Insights — all configured natively for .NET workloads without manual infrastructure management.
Azure Functions (Serverless)
.NET isolated worker processes run as event-driven serverless functions — triggered by HTTP requests, Service Bus messages, Cosmos DB changes, timer schedules, or Dataverse events. Pay only for execution time, scale to zero when idle, and burst to thousands of instances under load.
Azure SQL & Cosmos DB
Entity Framework Core provides an object-relational mapper purpose-built for .NET, offering LINQ queries, migrations, and change tracking against Azure SQL. For globally distributed, multi-model data needs, Cosmos DB's .NET SDK delivers sub-10ms reads with turnkey global replication.
Azure DevOps & GitHub Actions
Build, test, and release .NET applications through automated pipelines integrated with Azure Repos or GitHub. Infrastructure as Code with Bicep or Terraform, automated testing with xUnit, and continuous deployment to any Azure resource — all from a single, auditable workflow.
Azure Service Bus & Event Grid
Enterprise-grade messaging and event routing for distributed .NET architectures. Decouple your microservices, handle peak loads with message queuing, and orchestrate complex event-driven workflows that span Dynamics 365, custom APIs, and third-party systems.
Azure Identity & Key Vault
Managed identities eliminate the need for stored credentials. .NET applications authenticate to Azure resources — databases, storage, APIs — using Azure AD tokens, while Key Vault centrally manages secrets, certificates, and encryption keys with hardware-backed security.
.NET in the Dynamics 365 Ecosystem
Custom code that extends your Microsoft Success
.NET is the underlying runtime of Dynamics 365 and Power Platform. When you need to go beyond what configuration allows, .NET is how you get there — natively, supportably, and at scale.
Dynamics 365 CRM / Customer Engagement
Dynamics 365 CE runs on the Dataverse platform, which exposes a rich .NET SDK for server-side extensibility. When business rules, workflows, or Power Automate flows reach their limits, .NET plug-ins and custom workflow activities step in to handle complex, high-performance logic at the platform level.
Stallions' developers write C# plug-ins that execute synchronously or asynchronously within the Dataverse pipeline, ensuring your custom logic runs with full transactional integrity and access to the entire execution context.
- Custom plug-ins for complex business logic — validation, calculations, and cross-entity orchestration that runs inside the Dataverse transaction pipeline
- Custom APIs and custom actions that expose bespoke operations as first-class Dataverse endpoints, callable from Power Automate, JavaScript, or external systems
- Integration middleware using Azure Functions or ASP.NET APIs to sync CRM data with ERP systems, legacy databases, or third-party platforms
- PCF (PowerApps Component Framework) controls built with TypeScript and React, extending the CRM UI with custom grids, visualisations, or embedded experiences
- External portals and customer-facing applications that read and write to Dataverse via the Web API, providing branded self-service experiences
Power Platform Extensions
The Power Platform — Power Apps, Power Automate, Power BI, and Copilot Studio — is built for rapid, citizen-led development. But enterprise deployments frequently encounter scenarios where low-code reaches its ceiling: complex algorithms, high-volume data processing, or integrations that require custom authentication and error handling.
That's where .NET custom connectors, Azure Functions, and API Management enter the picture — bridging the gap between what business users build in Power Apps and the enterprise-grade backend services they need to connect to.
- Custom connectors backed by .NET APIs that expose line-of-business systems, legacy databases, or third-party services to Power Apps and Power Automate
- Azure Functions as the compute layer behind Power Automate flows — handling transformations, validations, and orchestrations too complex for expressions
- API Management gateways that provide security, throttling, and monitoring for APIs consumed by canvas apps and model-driven apps
- Power BI embedded analytics driven by .NET backend services that aggregate, transform, and cache data from multiple sources
- Copilot Studio plugin actions backed by .NET APIs, enabling AI assistants to perform real business operations securely
Dynamics 365 Finance & Operations
D365 F&O is built on the X++ language, which itself compiles to .NET CIL (Common Intermediate Language). The platform's extensibility model relies heavily on .NET patterns — class extensions, Chain of Command, and event handlers — making C# and .NET knowledge directly transferable.
Beyond the X++ layer, Stallions builds external .NET services that integrate with F&O's OData APIs, batch processing framework, and Data Management Framework to extend functionality without modifying the core platform.
- External .NET integration services that consume D365 F&O OData and REST endpoints for warehouse management, procurement automation, and financial reconciliation
- Custom electronic reporting configurations and external processing services for regulatory compliance, tax calculations, and multi-jurisdiction financial reporting
- Azure Logic Apps and Functions orchestrating data flows between F&O, CRM, third-party logistics providers, and banking systems
- Custom workspace tiles and embedded Power BI dashboards driven by .NET backend data aggregation services
- ISV solution development — building distributable packages that extend F&O for industry-specific verticals like local government, transport, and public sector
Development Philosophy
Low-code implementation vs. custom development
These aren't competing approaches — they're complementary tools in the same toolbox. The difference is knowing when each one delivers the most value.
No-Code / Low-Code
- Configure, don't code — use out-of-the-box entities, forms, views, and business rules to deliver requirements through platform configuration
- Rapid deployment in days or weeks, not months, leveraging Microsoft's pre-built modules and templates
- Citizen developers and functional consultants can own the build, reducing dependency on engineering teams
- Automatic platform updates — Microsoft handles infrastructure, security patches, and feature rollouts
- Ideal for standard CRM processes, approval workflows, simple data collection apps, and dashboards
Custom .NET Development
- Full control over architecture, performance, and logic — no platform constraints or expression limitations
- Enterprise scalability with containerised microservices, load balancing, and horizontal scaling patterns
- Deep integration with external systems through custom middleware, message brokers, and event-driven architectures
- Automated testing, CI/CD pipelines, code reviews, and DevOps practices ensure production-grade reliability
- Ideal for bespoke platforms, high-volume processing, complex algorithms, and IP-rich proprietary applications

Discovery & Architecture
We begin with deep-dive workshops — often through our complimentary Day On-Site — to understand your business processes, pain points, existing technology landscape, and integration requirements. We map out the solution architecture, identifying which components belong in D365 configuration, which in Power Platform, and which require custom .NET development.
Platform-First Design
We exhaust every platform-native capability before introducing custom code. D365 entities, business rules, security roles, Power Automate flows, and canvas apps are designed and validated first. Only the gaps — the requirements that genuinely cannot be met through configuration — are earmarked for .NET development.
Agile .NET Development
Custom components are built in two-week sprints using Azure DevOps for backlog management, CI/CD pipelines, and automated testing. Every sprint produces a deployable increment — plug-ins, APIs, integration services, or frontend components — reviewed and validated against acceptance criteria.
Integration & Testing
Custom .NET components are integrated into the broader D365 and Power Platform ecosystem with end-to-end testing. We validate plug-in performance within Dataverse, API throughput under load, data integrity across systems, and user acceptance across all roles and scenarios.
Deployment & Knowledge Transfer
Solutions are deployed through managed release pipelines with rollback capabilities. We provide comprehensive documentation, admin guides, and hands-on training so your team can confidently manage, extend, and support the solution independently. Our managed support plans are available for ongoing needs.
One partner. The entire Microsoft stack. No gaps.
What makes Stallions Solutions different is that .NET development doesn't exist in isolation here. It sits alongside our deep expertise in Dynamics 365 CRM, Finance & Operations, Power Platform, Azure infrastructure, AI & Copilot, SharePoint, and Office 365. That means when your CRM implementation needs a custom portal, when your Power App needs a high-performance backend, or when your F&O deployment needs an integration layer — the same team handles it all, with consistent architecture, shared context, and zero handoff friction.
This is what it means to be a true one-stop shop: not just offering services across the stack, but delivering them as a unified, coherent solution where every component is designed to work together from day one.
Stallions Solutions delivers innovative business management solutions as a Microsoft Certified Partner. Our experienced consultants design customised solutions using Dynamics 365, Power Platform, Azure, Machine Learning, and SharePoint to optimize processes and improve bottom lines.
