Run one-shot commands under Visual Studio developer prompt. Use any shell with Visual Studio developer prompt. Dump developer prompt environment variables.
For fast startup, use the --read-cache and --write-cache options. The cache will contain all environment variables in plaintext, so make sure you don't have any sensitive data in your environment variables when using --write-cache. The cache will be automatically regenerated when the underlying Visual Studio installation is detected to be updated.
