PSSPL is a .NET Core development company that develops web apps, APIs, and cloud-native apps using ASP.NET Core and .NET 10, and assists in modernizing the legacy .NET platform before time runs out for your present .NET version. Be it a fresh project development, migration from .NET Framework, or just manpower support for running an application in production, our ASP.NET Core development services revolve around a single principle – develop and deliver solutions that work and can be quantified.
Thereafter, neither of them will receive any security or reliability updates by Microsoft. .NET 10 is the LTS version, and it will be supported until November 2028. For those who have their application in .NET 8, .NET 9, or even older .NET Framework, it is now time to make plans for the transition – not the next week, when you are forced to patch because support has ended.
ASP.NET Core development services encompass the design, development, migration, and ongoing support of web applications, REST and gRPC APIs, microservices, and cloud-native systems built on ASP.NET Core, the web framework within Microsoft’s unified .NET platform (currently .NET 10 LTS).
As a Microsoft Solutions Partner, PSSPL provides end-to-end ASP.NET Core development services, including custom application development, .NET Framework modernization, cloud and container deployment, security hardening, and long-term application support.
The unified, cross-platform runtime and SDK underlying all modern .NET development (currently version 10).
The web framework built on .NET, used to develop web applications, APIs, and cloud-native services.
The earlier, Windows-only platform (up to version 4.8.1). Still supported by Microsoft, but no longer the target for new development.
Designated in Data & AI, and Digital & App Innovation. Recognized by Microsoft for consistent delivery quality and technical capability.
Current-platform development, with proven migration experience from .NET Framework, MVC, and Web Forms. Every engagement is evaluated against Microsoft's official version roadmap.
Independently certified quality management and information security. Certifications are audited and renewed on a recurring cycle, not a one-time claim.
Offices across the USA, UK, Australia, and India, supporting time-zone-aligned engagement. Clients work with a consistent team, regardless of region.
Sustained delivery across the Microsoft technology stack. A track record built on long-term client relationships rather than one-off projects.
A core team of ASP.NET Core engineers and architects, not developers shared across unrelated technology stacks. Specialization that carries through discovery, build, and support.
Single point of accountability from discovery through migration, deployment, and long-term production support. No handoffs between disconnected vendors or teams.

Dedicated ASP.NET Core Developers
Professional engineers assigned to work with clients as part of their team and existing development workflow.
Legacy .NET Modernization
Migration of legacy .NET applications into a modernized architecture which is supported and cloud-friendly.
.NET Framework to .NET 10 Migration
Migration of applications from .NET Framework and .NET 8/9 before end-of-support into .NET 10 LTS.
Cloud & Container Deployment
Deployment of applications to cloud platforms such as Azure, AWS, or Google Cloud using containers and Kubernetes.
Performance Optimization
Profiling, caching techniques, asynchronous operations, and Native AOT when applicable to cut down latency and cost infrastructure.
Security Hardening
OWASP-compliant security checks, authentication and identity services, secret management, and dependency vulnerability assessments.
Testing & Quality Engineering
Automated unit, integration, API, and end-to-end test automation embedded in the delivery pipeline. Learn more about QA as a Service offering.
Support & Version Upgrades
Regular updates, SDK and runtime upgrades, and SLA-based support to ensure that applications stay at supported version levels.
Current Platform
.NET 10 is the current Long-Term Support release, supported through November 2028. PSSPL builds new applications on .NET 10 and targets it in all migration engagements, focusing on the platform capabilities that directly affect architecture and total cost of ownership.
Modern hosting by Kestrel, minimal hosting, and cross-platform deployment on Linux, Windows, and containers.
Efficient HTTP APIs that offer excellent performance characteristics and are well-suited for microservices and internal use cases.
Startup and runtime improvements for compatible scenarios that are not reliant on reflection-dependent code and specific libraries.
Selection of server, WebAssembly, and hybrid rendering models based on latency, offline capabilities, and reach.
Tracing, metrics, and logs that work with Application Insights, Grafana, or any other monitoring system.
OAuth 2.0, OpenID Connect, JWT and managed identities for secure access.
Modern data access capabilities with improved performance and migration capabilities.
Resilience pipeline and health checks and graceful degradation for dependent services.
Containerized, pipeline-driven delivery to Kubernetes and managed platforms.
For organizations on .NET Framework, Web Forms, ASP.NET MVC, or a .NET 8/9 build approaching end-of-support, PSSPL plans a structured migration path to .NET 10, including compatibility assessment, parallel-run validation, and rollback planning.
Migration Approach — The 4 R’s
| Approach | Applicable When |
|---|---|
| Rehost | The application is stable and the primary requirement is infrastructure or hosting change. |
| Replatform | Cloud, container, or managed-service benefits are needed with limited code change. |
| Refactor | Maintainability, scalability, or release velocity is the core constraint. |
| Rebuild | The existing architecture prevents meaningful modernization. |
How we deliver
Goals, existing systems, constraints, and risks evaluated.
Target architecture and data strategy planned along with delivery sequence.
Interfaces and UX designed before implementation.
Delivery done in increments rather than in one big release.
Unit, integration, API, and end-to-end testing part of the pipeline.
Threat modeling and OWASP validation.
Pipeline configuration, infrastructure-as-code, and environment automation.
Controlled rollout with monitoring and rollback readiness.
Ongoing observability, SLA management, and version upgrades.
We’re direct about what we work with because vague claims about “cutting-edge technology” don’t help you evaluate whether we’re the right fit.

ASP.NET Core serves as the application platform, with AI capabilities delivered through external services such as Azure AI, OpenAI, ML.NET, or client-owned models, integrated via API. PSSPL builds both the application and the governance layer required for AI to operate reliably in production.
Regulatory compliance — including GDPR, HIPAA, and similar frameworks — depends on project scope, jurisdiction, and organizational controls. PSSPL implements and documents the relevant technical controls for each engagement in line with client requirements.
Project cost is determined by application complexity, number of integrations, UI/UX requirements, migration risk, cloud architecture, security and compliance requirements, team composition, and support expectations.
To prepare an estimate, PSSPL evaluates project type, current technology stack and version, timeline, target cloud platform, integration requirements, migration scope, and approximate team and budget parameters.
Share your current technology stack and objectives. PSSPL will assess compatibility, recommend a .NET 10 migration path, and scope the engagement — including a structured migration off .NET 8/9 ahead of end-of-support.

The .NET is the underlying cross-platform runtime and SDK, currently in its 10th version. The ASP.NET Core is the web framework that runs on the .NET for web application and APIs and real-time service development.
The .NET 10 is the latest LTS version, which is maintained until November 2028. The .NET 8 reaches EOL by 10 November 2026. All new development and applications with long lifetimes should be developed on the .NET 10.
