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 โ 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).

.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.
| 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. |
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.

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 โ including GDPR, HIPAA, and similar frameworks โ 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 โ including a structured migration off .NET 8/9 ahead of end-of-support.
