Recent changes made to the C# sdk (version 3.x) are causing some file upload issues.

Hi,

The changes made to the official c# sdk recently are creating some issues while uploading files, corrupting them.

I bielive the DefaultHttpClient is in cause (on my solution i made change to override the method Resquest1 to revert it to its previous behaviour).

Could you have a look at the issue : https://github.com/smartsheet/smartsheet-csharp-sdk/issues/51 .

Thanks.
