NuGet MCP Server doesn’t work in GitHub Copilot Chat window even after restarting

[v-luzh]

NuGet Product Used

Visual Studio Package Management UI

Product Version

VS Main\11625.112 + NuGet Client Dev\7.6.0.33

Worked before?

It's a regression since it doesn’t repro on VS Main\11617.104 + NuGet Client Dev\7.6.0.22.

Impact

It's more difficult to complete my work

Repro Steps & Context

Note:

1. Repro rate: 100%

Repro Steps:

1. Create a C# Console App (.NET 10.0) in VS and open the project-level PM UI.
2. Go back to the ‘Browse’ tab of PM UI, select the source ‘nuget.org’ from the ‘Package source’ dropdown list and select a vulnerable package from the ‘Version’ dropdown list (for example, Newtonsoft.Json 11.0.2 in this instance).
3. Install the vulnerable package and click the ‘Installed’ tab.
4. Go to the Solution Explorer window and click the link ‘Fix with GitHub Copilot’ on vulnerability InfoBar at the top of Solution Explorer window.
5. Click the ‘select tools’ button (the spanner icon) on the bottom-right of GitHub Copilot Chat window.

Expected Result:

No error occurs.

Actual Result:

NuGet MCP Server doesn’t work even after restarting as the screenshot below.

Potentially affected by NuGet/NuGet.Client@4ee8cd0?

I just updated to latest build, its using the new version of the MCP server and its working.

@v-luzh can you open the output window, switch to GitHub Copilot output, and copy/paste any output related to the NuGet MCP server?
