`dotnet new --uninstall` not working for folder templates

Unable to uninstall folder-based templates

This could be an issue with the dotnet net --uninstall (or dotnet new -u) command, or just an issue with uninstall documentation, but it doesn’t seem possible to uninstall a template via a folder template.

General

Steps

1. Create template folder (.template.config folder with a template.json file)

   I have confirmed it with this JSON config.

   {
       "$schema": "http://json.schemastore.org/template",
       "author": "Some Author",
       "classifications": [ "Some", "Various", "Search Keywords" ],
       "identity": "Some.Identity",
       "shortName": "name-used-in-dotnetnew",
       "name": "Some Template Name"
   }
   

2. Install template

   dotnet new --install ./some-template-folder/
   

3. [optional] Use newly-installed template

   The template "Some Template Name" was created successfully.
   

4. Attempt to uninstall template

   dotnet new --uninstall ./some-template-folder/
   

   Instead of uninstalling, I keep getting this error message.

   Could not find something to uninstall called '.\some-template-folder\'.

This happened with .NET Core SDK v1.1.0 and v2.0.0.

@patridge - I believe you have discovered a bug. Could you try uninstalling one more time, using the full path, but without a trailing slash: dotnet new --uninstall "C:\full\path\to\some-template-folder"

Could you also let me know the output from running dotnet --version?

I filed a PR for clarifying this in the docs here: dotnet/docs#3054, regardless of any internal changes required.
