Pinning a specific Version

2dog already pins your project to a specific version in Directory.Build.props. You can edit this file manually.

You can also choose the version of the 2dog tool that you run. Separately, you can choose the version of the 2dog packages that the tool uses.

Run a specific tool version

Add @ and the version number after 2dog:

dnx 2dog@4.7.2.154 doctor

Replace the number with the version that you want to use. This example runs doctor from that release of the tool. If that release is not on your computer, dnx downloads it.

Use the same syntax with other commands. For example, this command previews a project update with the selected tool version:

dnx 2dog@4.7.2.154 update --dry-run

Remove --dry-run to apply the update. The update command changes the project's package versions to the tool's versions; it does not downgrade newer versions. See update for details.

Print the version

Use the version command to show the tool's version and its package versions:

dnx 2dog@4.7.2.154 version

--version belongs to dnx and chooses the tool version. version is a 2dog command and prints version information. See the version command reference for the output format.

Keep the project's package versions

Projects created by 2dog store their package versions in Directory.Build.props. For example:

<Project>
  <PropertyGroup Label="2dog">
    <TwoDogVersion>4.7.2.154</TwoDogVersion>
  </PropertyGroup>
</Project>

This is a shortened example; keep the other version properties in your file. Projects use $(TwoDogVersion) in their package references.

Only 2dog update changes this value. This value does not select the tool that dnx runs. To select the tool, use @version.
