Uploading more than 4 MB file using Client object model

cant upload the file more than 3 MB to SharePoint Library using Client Object model.

Following is the two ways i tried.

Way 1:

using (FileStream fs = new FileStream(strCurrentTempPath, FileMode.Open))
{                    SP.File.SaveBinaryDirect(ClientContextName,ServerRelativeUrl, FileStream, true);
}

Microsoft.SharePoint.Client.File file = oWeb.GetFileByServerRelativeUrl(ServerRelativeUrl);

FileVersionCollection versions = file.Versions;

FileSaveBinaryInformation fsbi = new FileSaveBinaryInformation();

ClientContext ctx = new ClientContext(RootUrl);
byte[] binaryData =System.IO.File.ReadAllBytes(strCurrentTempPath);

fsbi.Content = binaryData;
file.SaveBinary(fsbi);

clientContext.Load(file);
clientContext.Load(versions);
clientContext.ExecuteQuery();
