.NET Development Specialists
From maintaining business-critical ASP.NET WebForms systems to building modern .NET web applications, we bring deep Microsoft-stack expertise to wherever your business needs it.
NorthWest Software Solutions is a .NET development shop comfortable at both ends of the spectrum. We maintain and stabilize legacy ASP.NET WebForms and .NET Framework systems, and we build new solutions on modern .NET without losing sight of the business value already locked inside your existing applications.
Our team has spent years in the Microsoft stack: classic WebForms codebases, SQL Server at every scale, and modern ASP.NET Core applications. Wherever your project sits, we bring the right experience to move it forward.
Ongoing bug fixes, performance tuning, and stability improvements for your existing ASP.NET WebForms or .NET Framework applications. We keep the lights on and the wheels turning.
New projects built on modern ASP.NET Core and .NET 8/9 — clean architecture, REST APIs, Blazor, and more. We're equally at home building greenfield as we are maintaining the old.
Need new functionality added to an existing app — legacy or modern? We fit features naturally into your codebase without destabilizing what already works.
Schema design, query optimization, and full migrations to Microsoft SQL Server — including moving off Access, Excel-as-a-database, or other ad-hoc data stores into a proper production-grade SQL Server environment.
Legacy applications are frequent targets. We audit, patch, and harden your .NET apps against common vulnerabilities — keeping your data and users protected.
Step-by-step migration paths — upgrading .NET Framework versions, moving to ASP.NET Core, replacing deprecated components — without a risky big-bang rewrite.
Slow page loads and database bottlenecks dragging you down? We profile and optimize across the stack — .NET code and SQL Server queries alike.
Inherited an undocumented codebase? We audit, document, and provide clear roadmaps so you understand what you own and what your options are.
We assess your application honestly. If maintenance is the right call, we say so. If a modern rebuild makes sense, we'll tell you that too — with a real plan, not a sales pitch.
From WebForms and .NET Framework to ASP.NET Core and SQL Server — we work across the Microsoft ecosystem and bring genuine depth, not surface-level familiarity.
We prioritize stability. Every change is tested, reviewed, and deployed carefully so your production environment stays healthy.
Plain-language updates, honest timelines, and no technical jargon for jargon's sake. You always know where your project stands.
Tell us about your .NET project — whether it's a legacy system in need of care, a database migration, or something new you want to build. We're happy to have an initial conversation at no charge.
