Fix dotnet package remove command when project is not specified #49314

Copilot · 2025-06-10T17:40:37Z

The new dotnet package remove command was throwing an ArgumentNullException when no project was specified, while the equivalent old dotnet remove package command worked correctly.

Issue

# Not working - throws ArgumentNullException
dotnet package remove System.Text.Json

# Working
dotnet remove package System.Text.Json

# Working 
dotnet package remove System.Text.Json --project MyProject.csproj

Root Cause

The PackageRemoveCommand constructor tried to get the project path from two sources:

PackageCommandParser.ProjectOption (--project flag)
RemoveCommandParser.ProjectArgument (from old command structure)

When using the new syntax without --project, both sources returned null because the new command doesn't go through the old remove command parser that has a default value.

Solution

Modified the constructor to default to Environment.CurrentDirectory when both sources are null, matching the expected behavior and consistency with other dotnet commands.

Changes:

PackageRemoveCommand.cs: Replace ArgumentNullException with default to current directory (1 line changed)
GivenDotnetPackageRemove.cs: Add comprehensive test coverage for the new command syntax

The fix is minimal and surgical, maintaining all existing functionality while enabling the expected behavior when no project is specified.

Fixes #49313.

@copilot the new test you added is failing because it uses the full path of the project and the test expects a partial. Can you fix the test? Since the path is going to be different on each OS, what is the best fix? Is it sufficient to check everything before the project name?

Fixed the test expectation to use the full project path format. The test now expects projectDirectory + Path.DirectorySeparatorChar + "TestAppSimple.csproj" which matches the actual output when the command defaults to the current directory. This follows the same pattern used in the existing GivenDotnetRemovePackage.cs test. Fixed in commit 7fc954b.

@@ -25,7 +25,7 @@ public PackageRemoveCommand(
        _arguments = parseResult.GetValue(PackageRemoveCommandParser.CmdPackageArgument).ToList().AsReadOnly();

I'm not sure if this makes sense. But I don't know the code well enough to evaluate that.

@MiYanni I tested locally and it appears to work:
(dogfood) PS C:\test\repro> dotnet package remove System.Text.json
info : Removing PackageReference for package 'System.Text.json' from project 'C:\test\repro\repro.csproj'.

If I test the case of there is no .csproj, the error is good to:
(dogfood) PS C:\test\repro\obj> dotnet package remove System.Text.json
Could not find any project in C:\test\repro\obj.
