* Update dotnet-mcp-builder skill to ModelContextProtocol 2.x Align the skill with the C# SDK 2.0.0 release and the MCP 2026-07-28 spec: stable line is now 2.x, HttpServerTransportOptions.Stateless defaults to true, roots/sampling/MCP-channel logging are [Obsolete] (MCP9005) with the multi-round-trip input_required pattern as the replacement, discovery-first negotiation (server/discover) supersedes the initialize handshake, Mcp-Method/Mcp-Name routable headers, raw structuredContent for non-object results, required Tool.inputSchema, and the new ModelContextProtocol.Extensions.Tasks and ModelContextProtocol.Extensions.Apps packages (typed MCP Apps support replacing the hand-rolled _meta/ui:// pattern on 1.x). * Address Copilot review: Apps extension accuracy, header scope, capability ownership - packages.md: the Apps package replaces the manual _meta wiring, not the ui:// resource; note the experimental MCPEXP003 diagnostic; label the 1.x -> 2.0 list as highlights and add the OAuth/SSE runtime changes with a pointer to the full release notes. - transport-http.md: Mcp-Method is on every POST, Mcp-Name only on named invocations (tools/call, prompts/get, resources/read) - do not require it globally at gateways. - mcp-apps.md: current MIME type is text/html;profile=mcp-app (skybridge is a legacy draft value); document [McpAppUi] + WithMcpApps(). - server-features.md: roots/sampling are client capabilities, only logging sits on ServerCapabilities. * Correct stateful HTTP guidance: 2026-07-28 has no HTTP sessions Per the official SDK v2 elicitation docs, a server with Stateless=false refuses the 2026-07-28 revision so dual-path clients fall back to an initialize-capable revision; ElicitAsync cannot be used on 2026-07-28 Streamable HTTP at all. Reframe stateful HTTP as down-level compatibility mode and document the multi-round-trip pattern (InputRequiredException / InputRequest.ForElicitation, retry with InputResponses -> ElicitResult) as the current-protocol way to ask mid-tool, across SKILL.md, transport-http.md, and elicitation.md.

Install a Plugin
For most users, the Awesome Copilot marketplace is already registered in the Copilot CLI/VS Code, so you can install a plugin directly:
copilot plugin install <plugin-name>@awesome-copilot
If you are using an older Copilot CLI version or a custom setup and see an error that the marketplace is unknown, register it once and then install:
copilot plugin marketplace add github/awesome-copilot
copilot plugin install <plugin-name>@awesome-copilot
