.NET Core 3.0 sdk

This package installs the .NET Core 3.0 sdk for your platform and provides the dotnet executable.

No elevation/root required.

Partners with the dotnet-sdk-3.0 package.

Usable as a standalone but also for shipping .NET based packages:

Scenario 1: Global Installation

To make the dotnet command available globally, run

`` Haskell seems to provide nice highlighting
npm i -g dotnet-3.0 // for running dotnet apps
npm i -g dotnet-sdk-3.0 // for developing dotnet apps
`

Scenario 2: Dependency

When installed as a dependency of a package, the dotnet command will be available to that package's scripts.
This enables a very simple development and shipping experience for platform-independent .NET based applications.

The following package.json uses both the dotnet-sdk-3.0 and dotnet-3.0 in order to simplify both developing and shipping the package.

` json
{
"name": "contoso",
"version": "1.33.7",
"description": "Contoso C# app",
"scripts": {
"build": "dotnet build src/contoso.csproj",
"test": "dotnet test src/contoso.test.csproj",
"start": "dotnet bin/netcoreapp2.0/contoso.dll"
},
"devDependencies": {
"dotnet-sdk-3.0": "*"
},
"dependencies": {
"dotnet-3.0": "*"
}
}
`

This allows consuming the contoso package easily as a standalone using

` Haskell seems to provide nice highlighting
npx contoso
`

or when installed (e.g. as a dependency of another package) using

` Haskell seems to provide nice highlighting
npm start
`

Unsurprisingly, during development the following commands will work:

` Haskell seems to provide nice highlighting
npm run build
npm run test
`

Technical Details

$3

We created several platform-specific helper packages that actually provide the promised dotnet installation (e.g. dotnet-sdk-3.0-win).
Such packages exist for Windows, Linux and MacOS.
Here, we will merely determine the executing platform, acquire the corresponding package and populate .bin with scripts forwarding any calls to the actual binaries.

$3

The platform-specific package (see above) is installed in a shared location in order to reliably deduplicate it across installations.
By default, the installation location is ~/.net/3.0 since it is accessible without elevation.

$3

DEBUG - set to 1 to show debugging messages from the caller/installer scripts

NO_NET_SDK - set to 1 to prevent the runtime runner for checking for and deferring to the SDK runner before using just the runtime.

DOTNET_SHARED_ARCH - overrides the architecture (one of osx, linux, win, win-ia32).

DOTNET_SHARED_HOME - overrides the base folder for installing dotnet runtimes/sdks. defaults to
- linux/osx: ~/.net
- windows: %USERPROFILE%\.net

$3

Since the .NET core tools and runtime both use a command called dotnet, both the runtime and sdk variants of this package do the same.
If you have both installed, it will by default use the SDK which should support the needs of runtime running too.

dotnet -- runs the SDK dotnet tool if installed, or falls back to running the runtime dotnet tool.

install-dotnet-sdk -- installs the shared .NET Core sdk if it's not installed. use --force` to overwrite if necessary
