As of 9.0.200, this isn't strictly true anymore - slnx files will be considered as well if they are present in the current directory.

Suggested change

	The solution file to modify. If unspecified, the command searches for a `.sln` file in the current directory.
	The solution file to modify. If unspecified, the command searches for a `.sln` or `.slnx` file in the current directory.

The command supports many more types of project files than just csproj or vbproj - I think the clarification here could be removed entirely.

Suggested change

	One or more paths to the project files (`.csproj` or `.vbproj`) that should be removed from the solution.
	One or more paths to the project files to remove from the solution.

We should add note here to explain the sln vs slnx probing algorithm that I described in the linked issue.

For consistency in the CLI documentation, these kinds of notes should go in a Description section near the top of the file, following the synopsis. Changes for formatting consistency are also needed in the examples section. The article also needs to be split into multiple files (one for each subcommand) to be consistent with what was done for dotnet workload and its subcommands. That requires changes to the other sln subcommands and to the TOC. It would probably be best for you to address only the comments that are easy to do and leave the rest for us.

@nileshsheth do you mind if we close this case? You can open an issue with your proposed changes. Right now we're heads down with the .NET 10 release, and your proposed changed would required significant time for use to review/make suggests/etc.
