This extension provides a unified way for other extensions like the C# and C# Dev Kit extensions to install local versions of the .NET Runtime, and machine-wide versions of the .NET SDK. Those extensions tell the .NET Install Tool when they would like a .NET SDK to be on the machine, and we install one for them if there's not already one that matches the SDK they need to run properly. Users can also install the .NET SDK themselves by reading below.
This extension was probably included as a dependency of one of the following extensions, though this list is not exhaustive:
The above extensions call into this extension to provide a unified way of downloading shared .NET Runtimes or .NET SDKs. If you already have an installation of .NET that you'd like to use, see the troubleshooting section below. If you want to remove this extension completely, you will need to uninstall any extensions that depend on it first. If this extension is uninstalled, any .NET Runtimes installed by it will also be removed.
As of version 2.0.2, you can install the .NET SDK using part of our private API via the VS Code Command Palette!
To use the feature: Bring up the command palette (ctrl + shift + p) and run the command: .NET Install Tool - Install the .NET SDK System-Wide.
The command will try to find the best version of .NET for you to install, but you can tell it to install other versions as well based on its prompt. Note this feature does not support all distros, WSL, nor preview or RC versions of .NET.
The rest of the extension functionality is still limited to other extensions that rely on our extension.
If you want to use your own installation(s) of .NET, you can either use one for all extensions in VS Code, or use different installations for specific extensions.
This is the path to an existing .NET host executable that will select a runtime based on what's installed beside it for an extension's code to run under.
C#, C# DevKit, and more have components written in .NET. This .NET PATH is the dotnet.exe or dotnet that these extensions will use to run their code, not your code.
Using a path value in which .NET does not meet the requirements of a specific extension will cause that extension to fail. The version of .NET that is used for your project is determined by the .NET host, or dotnet.exe. The .NET host picks a runtime based on your project. To use a specific version of .NET for your project, install the .NET SDK using the .NET Install Tool - Install SDK System-Wide command, install .NET manually using our instructions, or edit your PATH environment variable to point to a dotnet.exe that has an /sdk/ folder with only one SDK.
If you want to use the installation for all extensions, set the dotnetAcquisitionExtension.sharedExistingDotnetPath.
Example:
"dotnetAcquisitionExtension.sharedExistingDotnetPath": "/usr/share/dotnet/dotnet"If instead you want more granular control, add the requesting extension to the dotnetAcquisitionExtension.existingDotnetPath setting in your vscode.json settings file. You can read more about using external installations in our documentation, but here's an example of how to tell the C# extension to use your existing .NET installation:
"dotnetAcquisitionExtension.existingDotnetPath": [
{
"extensionId": "ms-dotnettools.csharp",
"path": "C:\\Program Files\\dotnet\\dotnet.exe"
}
]For C# Dev Kit you would use the same thing, but with the extension ID ms-dotnettools.csdevkit. Other extensions, like the MAUI and Unity extensions, will have their own extension IDs that you can find in the extension pane by right-clicking on them and choosing 'Copy Extension ID'.
NOTE: You'll need to make a new item in the settings array for each extension that uses this extension to acquire .NET.
It can sometimes take a while to download .NET. While the default download time is 600 seconds, if you need more time you can set the dotnetAcquisitionExtension.installTimeoutValue setting to change that timeout. Here's an example of increasing the download timeout to 11 minutes:
{
"dotnetAcquisitionExtension.installTimeoutValue": 660
}You can read more about changing the installation timeout in our documentation.
This is a known issue with axios, the system we use to make web-requests. The requests we make need to be routed through the proxy. We have logic to try to detect your proxy automatically. If your proxy does not get detected by us, please try adding it here. You may want to consider temporarily switching to version 1.7.2 of the runtime extension if you are still experiencing issues as this version does not use axios. Note that proxies that require additional credentials are not yet supported.
Note: GFW / China also blocks some of our requests, which may be why our extension thinks you are offline or times out.
You can add the proxy in the extension settings like following the advice above for timeouts.
{
"dotnetSDKAcquisitionExtension.proxyUrl": "https://your_proxy_url:port"
}Prior to the release of this extension, extension authors had no way of knowing if the .NET Runtime was installed on their target machines. Other solutions had a number of challenges:
- Duplication of .NET runtimes and slow updates: Each extension was acquiring its own copy of .NET, wasting disk space.
- Clean up: When extensions installed .NET in a non-VSCode-managed folder location it was likely to be left behind.
- Servicing and floating versions: It was difficult to ensure that extensions would use the latest releases, particularly without re-shipping their extension.
- Corrupted installations: Corrupted installations could arise when VS Code was shut down mid-download or unzip.
- Network security policies: Alternative installation methods could have resulted in errors due to blocking from network security policies.
- Locked down environments: Some developers are unable to freely install software, requiring the ability to install extensions manually via a VSIX.
- Missing dependencies: Users may run into situations where .NET cannot run as-is, requiring the installation of missing pieces.
This extension attempts to solve the above issues.
