Infragistics Ultimate 26.1 ships a complete AI toolchain – Agent Skills, the
Ignite UI CLI MCP server, and the Theming MCP server – across Angular,
React, Web Components, and Blazor. The release also introduces Grid Lite, a
free MIT-licensed open-source data grid, grid scroll performance gains of up
to 150% FPS at 100k rows, PDF export for every grid family, a new Intl-based
i18n engine, and new components including IgbQueryBuilder.

Ignite UI MCP Testbed: An Open-Source Bench for Measuring What Your AI Agent’s Tooling Actually Does
The Ignite UI MCP Testbed is a free, open-source end-to-end testing suite that runs one shared prompt across a matrix of supported platforms, AI models, and tooling variants, then lets you compare the results side by side. It currently covers web app generation tests against Angular, React, Blazor, and Web Components. Every run can include scenario-specific Playwright verification tests. No account, no license, no breaking changes - clone it and run your first test matrix today and evaluate how your AI agent skills and MCP servers perform.
MCP vs RAG: MCP-based retrieval beats a vector-indexed RAG on grounding and citation depth, but it's slower and more expensive. Use it for correctness-critical requests; keep RAG for high-volume, latency-sensitive ones.
MCP vs RAG is the central tradeoff this report measures: retrieval-augmented generation over a static vector index is the default architecture for AI documentation assistants, but it degrades silently as source documentation changes faster than the index is rebuilt. This report benchmarks that architecture against a Model Context Protocol (MCP) server that queries Ignite UI documentation and API definitions, using Anthropic Claude as the orchestrating model in both configurations.
A 32-test benchmark pitting a paid AI model (claude-sonnet-4-6) against a free one (big-pickle) on the same Ignite UI authentication build across Angular, Blazor, React, and Web Components. Both tied at 94% - the free model got there because Ignite UI MCP servers and Agent Skills supplied the exact component APIs and icon names it lacked. Web Components is the one case where the MCP server is required, not optional.
Ignite UI for Angular 22 ships derived themes for the Data Grid - set three color properties on grid-theme() and nested buttons, inputs, chips, and scrollbars realign automatically - plus a dedicated excel-filtering-theme() function and an updated Select dropdown position. Two default changes need attention on upgrade: input type is now box (ng update preserves the old line look), and Select positioning moved to AutoPositionStrategy.
Ignite UI for Blazor 26.1 brings the AI-assisted development toolchain to Blazor - four Agent Skills plus official CLI MCP support (documentation and API) for GitHub Copilot, Cursor, Claude Code, and JetBrains AI - and adds grid scroll-performance gains. It also ships three new components - the IgbChat preview, IgbSplitter, and IgbHighlight - plus a Dock Manager 2.1 update with two-way Layout binding and new pane and tab events. No breaking changes; supports .NET 8, .NET 9, and .NET 10.
AI results improve over time even when the model never changes - context accumulation across your dev stack. Run a clean-room test to measure your true baseline.
Seven paired benchmarks against Ignite UI for Blazor and Angular show what MCP servers and Agent Skills change in AI-assisted development: component compliance rises from 0/5 to 5/5 in every scenario where the untooled model ignored the library, single-prompt feature completion rises from 71% to 100%, and total session cost including corrections is equal or lower.
The latest Ultimate UI for Windows Forms release delivers a focused set of charting enhancements that give you more control over how your data looks, how it’s labeled, and how users can interact with it. From expanded marker styling options to a powerful new series type, an early preview of user-driven annotations, and a modern serialization upgrade, […]
