Couldn't find any project/solution.

Error message

Couldn't find any project/solution.

What it means

First of two sibling checks in AddAsync to ProjectNugetPackageAdder: when neither a projectFile nor a solutionFile can be determined (both null), the CLI cannot locate any target to install the NuGet package into, so it throws a CliUsageException. This branch fires before attempting to derive a project from the solution.

Solutions

1. cd into the folder containing your .sln (or pass --solution / --project explicitly) and re-run.
2. Verify the .sln / .csproj exists with 'ls *.sln *.csproj'.
3. Pass the path explicitly: 'abp add-package <pkg> --project ./src/Acme.MyProject/Acme.MyProject.csproj'.

Example fix

// before (run from /docs)
abp add-package Volo.Abp.AspNetCore.Mvc
// after
cd /repo/Acme.App
abp add-package Volo.Abp.AspNetCore.Mvc

string sln = Directory.GetFiles(Environment.CurrentDirectory, "*.sln").FirstOrDefault();
string proj = Directory.GetFiles(Environment.CurrentDirectory, "*.csproj").FirstOrDefault();
if (sln == null && proj == null)
{ Console.Error.WriteLine("No .sln or .csproj in current directory."); return; }

When it happens

Trigger: Running 'abp add-package <pkg>' in a directory that contains neither a .sln nor a .csproj, or calling AddAsync without passing solutionFile/projectFile when the current working directory has no recognizable solution/project.

Common situations: Wrong working directory (running from repo root, docs folder, or src subfolder with no .sln); deleted .sln; running the command inside a folder unrelated to the ABP solution.
