Proxy issues when installing MS C# Extension (omnisharp)

[FloMaetschke]

• VSCode Version: 1.7.0-insider
• OS Version: Windows Server 2008 R2

Steps to Reproduce:

1. Use Visual Studio Code with Corporate Proxy

settings.json contains:

	// The proxy setting to use. If not set will be taken from the http_proxy and https_proxy environment variables
	"http.proxy": "http://user:[email protected]:8080",
	"http.proxyStrictSSL": false,

2. Install C# Extension

Result:

Proxy works for Installation of Extensions and Update checking. The proxyStrictSSL works.
It seems that the OmniSharp Extensions Network Connection does not use http.proxyStrictSSL.
=> unable to verify the first certificate

The OmniSharp Log shows:

Attempting to download omnisharp-1.9-beta14-win-x64-net451.zip

The Debug Console of VSCode shows:

It's an OmniSharp issue and it's already logged there dotnet/vscode-csharp#579

Thx, for the linked temporary workaround. I can now use omnisharp.
