ASP.NET development services on .NET 10, rendered for search.

Founcy Solutions' ASP.NET development services build and upgrade ASP.NET Core applications on .NET 10 LTS: Razor Pages, MVC, Blazor and Web APIs. Every public route is server-rendered, so Google and AI crawlers receive complete HTML. On .NET 8 or 9? Support for both ends on November 10, 2026.

What are ASP.NET development services?

ASP.NET development services design, build, upgrade and support web applications on Microsoft's ASP.NET framework, written in C#. Today that means ASP.NET Core on .NET 10: Razor Pages and MVC for server-rendered sites, Blazor for interactive components, and Minimal APIs or Web API for services. Upgrades are a big share of the work, from .NET Framework and Web Forms or from .NET 8 and 9 as they reach end of support. Done well, an ASP.NET Core site is fast, secure, runs on Linux or Windows, and serves search engines complete HTML.

Runtime

what's included

ASP.NET Core development, built and upgraded right.

New builds and upgrades share the same foundations: a deliberate render-mode plan, a clean data layer and SEO handled in code.

01

Render-mode plan

Static SSR, Server, WebAssembly or Auto chosen per route, so public pages always ship real HTML.

02

.NET 10 build

MVC, Razor Pages, Blazor and Web API on the current long-term-support release.

03

Data layer

Entity Framework Core with versioned migrations, or Dapper where raw speed matters.

04

Identity

ASP.NET Core Identity or Microsoft Entra ID, with roles, policies and MFA.

05

SEO middleware

Redirect and canonical rules, a generated sitemap and JSON-LD, all written in code and covered by tests.

06

Tests & pipeline

xUnit and Playwright suites, CI/CD and staging slots. Existing apps also get an upgrade report.

built to rank

ASP.NET Core is great for SEO, if you set it up that way.

It renders on the server by default. The common traps are client-only Blazor on public pages and redirect rules buried in server config nobody reads.

how it works

Audit, architect, ship, keep current.

New build or upgrade, the order is the same: understand, plan, protect with tests, then change.

  1. 01

    Audit

    Code, NuGet packages, target framework, hosting and a performance baseline, including how search engines see the site today.

    → audit and upgrade report
  2. 02

    Architect

    Render modes per route, data access, authentication and hosting, decided and written down.

    → architecture decision record
  3. 03

    Build or upgrade

    Sprints with tests in place before any refactor, deployed to a staging slot after every merge.

    → working staging build
  4. 04

    Tune

    Load testing, Core Web Vitals, a security review and a crawl of the staging site.

    → launch checklist
  5. 05

    Support

    Monthly .NET patching and a planned move to each new LTS, well before the old one expires.

    → version roadmap

what drives the cost

What does an ASP.NET project cost?

Upgrade or new build, these four answers decide most of it. Set them to see your project type.

Starting point

Moving off .NET Framework is a port, not an upgrade.

Codebase size

More projects and pages mean more to test and verify.

Third-party packages

Old NuGet packages without current versions need replacing.

Hosting change

Moving from Windows/IIS to Linux containers adds pipeline and infra work.

faq

ASP.NET questions.

ASP.NET on .NET Framework is Windows-only and in maintenance mode. ASP.NET Core is cross-platform, open source and actively developed. Every new build should target ASP.NET Core on .NET 10.
.NET 10, the current long-term-support release, supported until November 14, 2028. .NET 8 and .NET 9 both reach end of support on November 10, 2026, after which they stop receiving security patches.
Yes. It renders HTML on the server, gives full control over routing, redirects and headers, and performs well. The one trap is client-only Blazor WebAssembly on public pages, so we prerender those routes or use static SSR.
Yes, though Web Forms doesn't exist in ASP.NET Core, so the UI moves to Razor Pages or Blazor and the business logic is ported. A YARP proxy lets the old and new apps run side by side while pages move across.
Whether it's a new build or an upgrade, the size of the codebase, third-party package compatibility, existing test coverage, the integrations involved, and hosting changes such as moving from Windows/IIS to Linux containers.
No. ASP.NET Core runs on Linux or Windows, on AWS, Google Cloud, on-premises IIS or any container platform. Azure does add tight integration with Entra ID and Microsoft's tooling, so it's often a good fit for Microsoft shops.
Yes. Common setups are architecture reviews, pairing on a hard problem, or taking ownership of a defined workstream such as the upgrade, the CI/CD pipeline or the public-facing site, while your team keeps the core product.
start your .net project

Get to .NET 10 before the deadline does.

Send the site or app you're running. We'll audit the framework, packages and hosting, and map a route to .NET 10 that keeps public pages server-rendered.
