Needed to work correctly with salesforcde streaming api and salesforce platform events.
Would be useful to add to the master branch and to the Nuget package

@stewoe - any idea when this commit will be pushed to nuget package. Since am using addheaders and if it is taking is there any alternative to add headers?

Doesn't look like this is ever going to get merged. @couchand, are you interested in maintaining a NuGet package for your fork?

I am also facing error, "
'LongPollingTransport' does not contain a definition for 'AddHeaders' and no extension method 'AddHeaders' accepting a first argument of type 'LongPollingTransport' could be found (are you missing a using directive or an assembly reference?)"
Can someone please help to resolve it ASAP?

I'm cleaning out my queue. It looks like this repo has been abandoned and this PR won't get merged.

@kjkrum I'm not interested in maintaining a NuGet package, but anyone who would like to is free to use this under the terms of the license of this repo.
