Workflow ≠ Multi-Agent

My graph structure is llm → tools → llm → … → END. The LLM decides which tool to call each step, but the topology is fixed. This is a ReAct Agentic Workflow, which is one agent with tools rather than a multi-agent system.

This distinction sounds pedantic until an interviewer asks "how do your agents communicate with each other?" and I have no answer because there's only one agent.

What I did well:

FastAPI streaming implementation is clean

Tool docstrings: this is how the model decides what to call, so vague descriptions directly hurt quality

System prompt placed before conversation history, prefix caching friendly

I’m building CodeMeridian, a local code knowledge graph for AI coding tools.

The idea came from a very specific pain: AI agents feel great on small repos, but once a project grows into MVP territory, they begin guessing from nearby files, stale docs, and half-remembered architecture rules.

CodeMeridian indexes C# and TypeScript/TSX into Neo4j, then exposes MCP tools so the agent can ask things before editing:

What calls this?

What tests cover it?

Is this graph stale?

What files are actually in scope?

It does not replace Copilot, Claude, Codex, or local models.

It is more like giving them a project map with a red line drawn around the dangerous parts.

If your business is still running on Classic ASP, this is the wake-up call you need. The web has moved on - and your application needs to move with it.

Classic ASP was a reliable workhorse in its time. But in 2026, it is a liability. No security updates, no modern framework support, no scalability for today's demands. The longer you wait, the higher the technical debt - and the greater the risk to your business.

ASP.NET Core is the answer. And migrating does not have to be overwhelming when you have the right roadmap.

Why Classic ASP is No Longer Viable

No Microsoft Support Classic ASP reached end of life years ago. There are no official security patches, no bug fixes, and no future updates coming. Every day your application runs on it is a day of unnecessary risk.

Security Vulnerabilities Modern web threats have evolved dramatically. Classic ASP lacks the built-in protections that today's applications require - leaving your data and your users exposed.

Talent Shortage Finding developers who know Classic ASP is increasingly difficult and expensive. The talent pool shrinks every year while demand for ASP.NET Core developers continues to grow.

Performance Limitations Classic ASP simply cannot match the speed, efficiency, and throughput of modern ASP.NET Core applications - especially under high traffic loads.

Cloud Incompatibility Modern cloud infrastructure on Azure, AWS, and Google Cloud is built around contemporary frameworks. Classic ASP does not fit naturally into containerized or serverless environments.

What ASP.NET Core Brings to the Table

Speed and Performance ASP.NET Core is one of the fastest web frameworks available today. Benchmarks consistently show it outperforming Classic ASP by significant margins in response time and resource efficiency.

Built-In Security Modern authentication, authorization, data protection, and HTTPS enforcement are baked directly into the framework - not bolted on as an afterthought.

Cross-Platform Freedom Run your application on Windows, Linux, or macOS. Deploy to any cloud provider. Classic ASP locks you to Windows IIS - ASP.NET Core sets you free.

Scalability by Design Whether you are handling hundreds or millions of requests, ASP.NET Core scales horizontally and vertically with ease - ready for whatever growth your business demands.

Active Community and Ecosystem A massive global developer community, thousands of NuGet packages, and regular Microsoft releases mean your technology stack stays current and well-supported for years to come.

Modern Development Experience Clean MVC architecture, Razor Pages, dependency injection, and full Visual Studio and VS Code integration make development faster, more maintainable, and more enjoyable.

The Migration Roadmap for 2026

Step 1 - Audit Your Existing Application Document every page, function, database connection, and third-party integration in your Classic ASP codebase. Know exactly what you are working with before you begin.

Step 2 - Choose Your Migration Strategy Depending on your application size and risk tolerance, choose between a full rewrite, a phased module-by-module migration, or a strangler fig pattern where the new system gradually replaces the old one.

Step 3 - Convert Your Code Translate VBScript logic to C#, migrate ADO database calls to Entity Framework, rebuild your UI layer with Razor Pages or MVC views, and replace legacy session management with modern state handling.

Step 4 - Test Thoroughly Unit tests, integration tests, performance benchmarks, security scans, and user acceptance testing are all essential before going live.

Step 5 - Deploy and Monitor Launch on a modern hosting environment with a solid rollback plan in place. Monitor performance closely in the first 30 days post-migration.

Who This Roadmap is For

Development teams managing inherited Classic ASP codebases

CTOs and IT managers planning their 2026 technology modernization strategy

Business owners facing performance or security issues with legacy web applications

Software architects designing large-scale migration projects

Enterprises evaluating the true cost of staying on outdated technology

The Bottom Line

Migrating from Classic ASP to ASP.NET is not just a technical upgrade - it is a business decision that affects your security posture, your development velocity, your scalability, and your long-term competitiveness.

The One Technologies has a proven migration methodology that covers every phase from initial audit to post-launch support - minimizing risk and maximizing the value of your modernized application.

2026 is the year to make the move. The roadmap is ready. Is your business?

If your C# application runs behind a proxy, you have probably run into an annoying issue with the Google BigQuery client libraries: your BigQuery data calls route through the proxy perfectly by setting the HttpClientFactory property on the BigQueryClientBuilder, but your authentication and token refresh requests ignore the proxy entirely and attempt to hit the standard network, causing timeouts.

The Solution

To resolve this, assign a proxy-wrapped credential to the GoogleCredential property instead of the legacy Credential property on the client builder.

Example code:

using System.Net; using Google.Apis.Auth.OAuth2; using Google.Apis.Http; using Google.Cloud.BigQuery.V2; // 1. Configure your corporate proxy IWebProxy proxySettings = new WebProxy("http://your-proxy-host:8080", bypassOnLocal: true) { Credentials = new NetworkCredential("username", "password") }; // 2. Wrap it inside Google's API HttpClientFactory HttpClientFactory proxyClientFactory = HttpClientFactory.ForProxy(proxySettings); // 3. Load credentials and attach the proxy factory to the Auth layer GoogleCredential credential = await GoogleCredential.FromFileAsync("path/to/service-account.json"); credential = credential.CreateWithHttpClientFactory(proxyClientFactory); // 4. Construct the client using the correct strongly-typed property BigQueryClient bigQueryClient = new BigQueryClientBuilder { ProjectId = "your-google-cloud-project-id", HttpClientFactory = proxyClientFactory, // Proxies BigQuery data calls GoogleCredential = credential // CRITICAL: Proxies Auth/token calls }.Build();

The Key Difference

builder.Credential = credential; $\rightarrow$ Fails to route authentication traffic through the proxy network.
