failing to download behind corporate proxy

When I try to install intellisense support in VS Code (v1.19.3) I get no output messages indicating failure and bakery is not added.

The dev tools show the following in the log >
`ERR Failed to download Cake Bakery from NuGet: Error: self signed certificate in certificate chain`
which is the proxy doing it's thing.

When this happened with browsing/installing vs code extensions, the following was needed in my settings.json which resolved the issue.
`"http.proxyStrictSSL": false,`

However the cake plugin for adding both debug or intellisense does not work due to certificate issues and the above setting has no effect.

I've tried uninstalling and reinstalling both cake and c# extensions in case is was anything corrupted but to no avail.

Start by reproducing Cake Bakery installation in VS Code v1.19.3 behind a corporate proxy and trace the NuGet download that reports a self-signed certificate error. Compare its proxy handling with VS Code's http.proxyStrictSSL setting; done means Bakery installs successfully through the proxy without the reported certificate failure.
