Make Tizen MSI Installers

On Windows, .NET uses .msi installers to track and manage worklaods and packs between Visual Studio and the CLI.

Right now Tizen just has the .nupkg for the file based system. This repo attempts to correctly wrap the packages in .msi installers and installer packages for consumption by VS and/or the CLI.

build.ps1

This script takes the .nupkg files and wraps them into msi files which is then wrapped back into .nupkg.

The reason for the double wrap is because although dotnet is using .nupkg for the actual work, Visual Studio requires that it be done via .msi installers per CPU architecture. And then the .nupkg that wraps the .msi is just for the fact that the CLI uses NuGet to aquire and install things.

The implementation of this script just runs a MSBuild project that takes the .nupkg files from a source (in this case I manually downloaded all the Tizen packages from nuget.org) and generates all the other packaging.

All the tools used by this process are tools found in dotnet/arcade and are available on the public dotnet-eng NuGet feed: https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet-eng/nuget/v3/index.json

Required Files

The files used by the build process are 2 types:

• *.nupkg
  These are the actual packages to wrap.
• vs-workload.props
  This file is used to set properties for the build as the convert.proj is reusable.
  There is a different version used in this file to the NuGet SemVer version as the .msi installers require a 4-part, integer-based version. So the current pattern we have been using is to take the NuGet version of 7.0.100-preview.13.30 and strip out the "preview" part and just use the build number 7.0.100.30.

  This does required that all the previews of the 7.0.100 version keep incrementing the build number. For example, if there is a preview 13 build with version 7.0.100-preview.13.30, then even if there is a preview 14, the build must be incremented and not restarted: 7.0.100-preview.14.31. To restart the version build, you will have to increment the 3rd version component to be something along the lines of 7.0.101 which will result in a SemVer version of 7.0.101-preview.14.1 and a .msi version of 7.0.101.1.

install-manifest.ps1

This script is a modified version of the script found at:

https://github.com/Samsung/Tizen.NET/blob/main/workload/scripts/workload-install.ps1

The modifications are to remove and worklaod/pack installation. All that it does is to make sure the workload manifest is on disk for the next/future installation of the workloads.

install-tizen.ps1

This script is just the basic dotnet command to install a workload:

dotnet workload install tizen --source $PSScriptRoot\bin\msi-nupkgs --skip-sign-check

There is an additoinal line in the script to remove the installation cache of .msi files for testing purposes.

The --skip-sign-check argument on the install is to disable the signing check during installation because I have not signed these files as I do not have access to any Samsung certificates. Also note, this check can be disabled by domain policies, so cannot be relied upon to always work.
