Installing without Internet connectivity

Some environments may not have access to the Internet and thus the marketplace to download extensions or dependencies dynamically. To install the C# language extension and dependencies without Internet access, the following is required:

NOTE: It is important that if extensions offer platform-specific versions, that you ensure you are downloading/installing the matching platform pieces. Failure to do so could put your VS Code environment in a non-functional state.

• Download and install the required .NET 8 runtime from https://dot.net/downloads
• Download the following VS Code extensions for your specific platform:
  • .NET Install Tool
  • C# language extension
  • Optional extensions such as the C# Dev Kit, MAUI, or IntelliCode for C#
• Follow the documentation to Install from VSIX in VS Code with the downloaded extension files
