iolysAI agents for Visual Studio 2026
Your compass through AI

Connect the right coding agent to your C# and .NET solution without leaving Visual Studio.

A major iolys advantage

Use the subscriptions you already pay for.

With supported provider CLIs, eligible Codex, Gemini, Kimi, and Kiro account access can travel into Visual Studio 2026. You are not forced to create a second, metered API setup just to use AI while developing C# and .NET applications.

ALSO SUPPORTED

Databricks, local models, and APIs

Connect Databricks Unity Catalog, use Ollama locally, or bring your own API credentials whenever that route fits better.

Your infrastructure. Your billing.

The problem

.NET developers should not be locked into one AI coding assistant.

AI models improve quickly, but switching providers still pushes C# developers toward another editor, another interface, and another workflow outside Visual Studio 2026.

01

Provider lock-in

Your .NET development workflow becomes tied to one vendor’s roadmap, models, and pricing.

02

Constant context switching

Powerful agents live outside Visual Studio 2026, separating the work from the code.

03

Local models left behind

Private and self-hosted options rarely fit naturally into the Visual Studio 2026 workflow.

The provider layer

One Visual Studio 2026 workspace.
Every useful route to AI.

iolys connects your C# and .NET solutions to multiple AI coding agents, so the provider can change while your development workflow stays familiar.

02

Use provider CLIs

Bring capable AI coding agents such as Codex, Gemini, Kimi, and Kiro into Visual Studio 2026 for C# and .NET work.

03

Connect APIs your way

Use OpenAI-compatible endpoints and Databricks Unity Catalog workspaces across cloud services and self-hosted infrastructure.

04

Run local with Ollama

Keep sensitive work close and use the local models that fit your machine and priorities.

05

Stay oriented

See the active machine, solution, workspace, session, provider, and model before work begins.

06

Keep control

Review tool activity, affected files, permissions, and sensitive actions in plain language.

Freedom by design

Use the AI access you already have for .NET development.

Your provider strategy should match the task—not the limitations of an extension.

Choose a subscription-backed CLI for agentic work, an API when you need direct model access, or a local endpoint when privacy and control matter most.

Why iolys exists

C# and .NET developers deserve the same freedom to choose.

Most AI coding innovation has centered on VS Code, while developers building C# and .NET applications in Visual Studio 2026 remain tied to a much narrower set of choices. iolys was built to change that.

Instead of asking developers to change tools whenever a better model appears, iolys lets the AI change behind a consistent, trustworthy Visual Studio 2026 experience.

Simple annual pricing

Choose the plan that fits your team.

iolys pricing covers the Visual Studio 2026 extension for your C# and .NET projects. Your provider subscriptions, API accounts, and local infrastructure stay yours.

FAQ

Clear answers before you choose a route.

Does iolys support C# and .NET projects?

Yes. iolys works from the active Visual Studio 2026 solution, including C# projects, .NET applications, libraries, tests, and multi-project solutions.

Is iolys an AI provider?

No. iolys is a provider-independent workspace that connects Visual Studio 2026 to models, agents, CLIs, and compatible APIs.

Can I use my existing AI subscriptions?

Yes. Where a supported provider CLI uses eligible account-based access, iolys brings that route into Visual Studio 2026. You do not have to buy separate pay-as-you-go API access for those connections.

Does it support local models?

Yes. iolys supports Ollama and is designed to work with local and self-hosted model routes alongside cloud providers.

Do I need to leave Visual Studio 2026?

No. The extension is built specifically for Visual Studio 2026 so conversations, workspace context, and agent activity stay close to your code.

What happens when I change providers?

The provider and model change; the core iolys interface, navigation, permission flow, and workspace context remain consistent.
