Cross-Platform. High-Performance. Cloud-Native by Design.
The Active Server Pages.NET Core has ranked among the fastest server-side frameworks for three years in a row, and it's the first version of .NET built to run natively on Linux and macOS, not just Windows. It also comes with essential enterprise features like built-in security, request handling, and configuration management already included, so teams spend less time on setup and more time building.
High Performance That Keeps Applications Responsive
Independent industry benchmarks have placed the framework at the top for real-world speed, year after year. Businesses that move from older systems typically see their applications respond 3 to 5 times faster, without any drop in reliability.
High Throughput
Low Latency

Common ASP.NET Core Challenges & How We Solve Them
Senior .NET engineers recognise these patterns before they become production incidents. Here is how we prevent or resolve each one.
EF Core N+1 Queries Causing Database Overload
Problem
API endpoints that return 200 records execute 200+ SQL queries. Database CPU at 90%. Response times above 2 seconds. Production incidents on busy days.
Solution
EF Core query audit with SQL Server Profiler or EF logging. Eager loading with .Include()/.ThenInclude(), .AsSplitQuery() for wide result sets, compiled queries for hot paths. Result: 90%+ query count reduction.
Scoped Service Resolved from Singleton — ObjectDisposedException
Problem
ObjectDisposedException or DbContext threading errors in production. Inconsistent data appearing in responses. Intermittent errors on high-traffic endpoints.
Solution
DI lifetime audit across all service registrations. IServiceScopeFactory pattern for Singleton services needing scoped services. ValidateScopes() in development to catch mismatches before production.
Unhandled Exceptions Leaking Stack Traces to API Consumers
Problem
Unhandled exceptions return stack traces to API clients. Security risk. Inconsistent error responses breaking client applications.
Solution
Global exception handling with IExceptionHandler (.NET 8) or UseExceptionHandler middleware. ProblemDetails RFC 7807 standard responses. Serilog structured logging for every exception with correlation IDs.
.NET Framework to .NET 8 Migration Stalling
Problem
Migration started 6 months ago. Still on .NET Framework for 60% of the application. Two codebases to maintain. Team velocity dropping.
Solution
Strangler Fig: new endpoints on ASP.NET Core, legacy on .NET Framework, reverse proxy routes traffic. Identify Windows-only dependencies and replace with cross-platform alternatives (e.g. gRPC for COM). Dedicated migration track alongside feature work.
DbContext Contention Under High Concurrency
Problem
Under load, SQL Server shows blocking chains. Deadlocks appearing in Application Insights. API latency spikes at 80%+ concurrency.
Solution
All EF Core calls made async end-to-end. .AsNoTracking() for read-only queries. AsSplitQuery() for wide includes. Redis caching for frequently read, rarely written data. SQL Server read replica routing for reporting endpoints.
JWT Authentication Not Validating Correctly in Production
Problem
401 Unauthorized errors in production but not in development. CORS errors on preflight. Token expiry not handled gracefully by frontend.
Solution
Environment-specific JWT configuration via Azure Key Vault or environment variables. CORS policy scoped to environment. ClockSkew tolerance set explicitly. Refresh token implementation with sliding expiry.
Six Problems Every .NET Team Encounters
Senior .NET engineers recognise these patterns before they become production incidents. Here is how we prevent or resolve each one.
EF Core N+1 Queries Causing Database Overload
Problem
API endpoints that return 200 records execute 200+ SQL queries. Database CPU at 90%. Response times above 2 seconds. Production incidents on busy days.
Root Cause
Lazy loading enabled, navigation properties loaded inside loops, missing .Include() for related entities, no split query evaluation.
Solution
EF Core query audit with SQL Server Profiler or EF logging. Eager loading with .Include()/.ThenInclude(), .AsSplitQuery() for wide result sets, compiled queries for hot paths. Result: 90%+ query count reduction.
Scoped Service Resolved from Singleton — ObjectDisposedException
Problem
ObjectDisposedException or DbContext threading errors in production. Inconsistent data appearing in responses. Intermittent errors on high-traffic endpoints.
Root Cause
Scoped lifetime service (e.g. DbContext) injected into a Singleton service. The DbContext is disposed after the first request, but the Singleton lives forever.
Solution
DI lifetime audit across all service registrations. IServiceScopeFactory pattern for Singleton services needing scoped services. ValidateScopes() in development to catch mismatches before production.
Unhandled Exceptions Leaking Stack Traces to API Consumers
Problem
Unhandled exceptions return stack traces to API clients. Security risk. Inconsistent error responses breaking client applications.
Root Cause
No global exception handling middleware. Individual try-catch blocks in every controller. No ProblemDetails standard error response format.
Solution
Global exception handling with IExceptionHandler (.NET 8) or UseExceptionHandler middleware. ProblemDetails RFC 7807 standard responses. Serilog structured logging for every exception with correlation IDs.
.NET Framework to .NET 8 Migration Stalling
Problem
Migration started 6 months ago. Still on .NET Framework for 60% of the application. Two codebases to maintain. Team velocity dropping.
Root Cause
Windows-only dependencies (COM interop, Windows registry, System.Web), no migration plan, attempting to migrate everything simultaneously.
Solution
Strangler Fig: new endpoints on ASP.NET Core, legacy on .NET Framework, reverse proxy routes traffic. Identify Windows-only dependencies and replace with cross-platform alternatives (e.g. gRPC for COM). Dedicated migration track alongside feature work.
DbContext Contention Under High Concurrency
Problem
Under load, SQL Server shows blocking chains. Deadlocks appearing in Application Insights. API latency spikes at 80%+ concurrency.
Root Cause
Long-running transactions holding locks, missing async/await on EF Core calls (blocking thread pool), no read-replica routing for read-heavy endpoints.
Solution
All EF Core calls made async end-to-end. .AsNoTracking() for read-only queries. AsSplitQuery() for wide includes. Redis caching for frequently read, rarely written data. SQL Server read replica routing for reporting endpoints.
JWT Authentication Not Validating Correctly in Production
Problem
401 Unauthorized errors in production but not in development. CORS errors on preflight. Token expiry not handled gracefully by frontend.
Root Cause
JWT signing key mismatch between environments, incorrect CORS policy for production origins, missing clock skew tolerance on token validation.
Solution
Environment-specific JWT configuration via Azure Key Vault or environment variables. CORS policy scoped to environment. ClockSkew tolerance set explicitly. Refresh token implementation with sliding expiry.

ASP.NET Core, endorsed by Microsoft, is an open-source technology. The mature framework of .NET Core brings forth benefits such as high performance, top-notch security, cross-platform compatibility, cost efficiency, Docker support, and the utilization of an asynchronous pattern in MVC.
ASP.NET Core offers numerous advantages for web development, including high performance, cross-platform support, enhanced security features, cost efficiency, and robust support for Docker. Its open-source nature and continuous updates make it an ideal choice for building modern and scalable web applications.
ASP.NET Core’s cross-platform compatibility ensures that users can access web applications seamlessly on a variety of devices, including Windows, macOS, and Linux. This means a consistent experience regardless of the device or operating system they are using, enhancing accessibility and user satisfaction.
ASP.NET and ASP.NET Core are both web development frameworks by Microsoft. However, ASP.NET is a framework for building Windows applications, while ASP.NET Core is a cross-platform, high-performance, and open-source framework designed for modern, cloud-based, and modular applications.
Migrating to ASP.NET Core offers benefits such as improved performance, enhanced modularity, cross-platform compatibility, and support for the latest web development practices. ASP.NET Core is designed to be more lightweight and provides a more modern and flexible development experience compared to traditional ASP.NET.
We are a team of experienced ASP.NET Core developers with a proven track record of delivering successful projects. We offer custom asp.net core solutions, agile development methodologies, and post-launch support.
