Search for a NuGet

I’ve seen some references to nuget search, but this obviously does not work for me.

nuget search
Unknown command: 'search'
NuGet.Commands.CommandException: Unknown command: 'search'

I’ve also seen some references to dotnet search, but that also fails:

dotnet search Microsoft.Azure.Storage.Common
You must install or update .NET to run this application.

App: /home/b0ef/.dotnet/tools/dotnet-search
Architecture: x64
Framework: 'Microsoft.NETCore.App', version '2.1.0' (x64)
.NET location: /nix/store/m4y7xyqcgnv1jq83smv9v71y9f145c7r-dotnet-sdk-7.0.302

The following frameworks were found:
  7.0.5 at [/nix/store/m4y7xyqcgnv1jq83smv9v71y9f145c7r-dotnet-sdk-7.0.302/shared/Microsoft.NETCore.App]

To install missing framework, download:
https://aka.ms/dotnet-core-applaunch?framework=Microsoft.NETCore.App&framework_version=2.1.0&arch=x64&rid=nixos.22.05-x64

That depends on .NET Core 2.1, which was released in 2018?

This is a .NET question, not a Nix question.

nuget search refers to nuget.exe only. dotnet search is a .NET global tool; there is no such thing as a self-contained global tool which means it’s the luck of the dice if it works with your installed runtimes, and NuGet does not have a way to search from the command line.

You can override the tool’s hard-coded desired runtime:

> dotnet tool install --tool-path .tools dotnet-search
> DOTNET_ROLL_FORWARD=MAJOR dotnet exec .tools/.store/dotnet-search/1.0.0/dotnet-search/1.0.0/tools/netcoreapp2.1/any/dotnet-search.dll

EDIT: I appear myself to not understand how .NET target frameworks work - I haven’t explicitly verified the below but I’m not longer sure it’s true; leaving it in for posterity. Something different is happening on my machine vs yours: my machine appears to be requesting runtime 7.0.7, and yours is requesting something from the netcoreapp2.1 era.

(By the way, you also appear not to understand how .NET target frameworks work. A netcoreapp2.1-framework tool can run on any runtime at or exceeding netcoreapp2.1, since all such runtimes implement the netcoreapp2.1 framework, and in particular such a tool can in principle run on the .NET 7 runtime. The thing that is wrong with this particular tool is that it has implicitly selected a runtime that is later than what you have installed, presumably because it was built with SDK 7.0.304. dotnet --list-runtimes shows that SDK 7.0.302 gives you runtime version 7.0.5.)
