I am trying to upload a file with size 40MB in Document Library using SharePoint 2010 Managed CSOM (C#).

I am using following code

ClientContext clientContext = new ClientContext(siteUrl);
CredentialCache myCache = new CredentialCache();
myCache.Add(new Uri(siteUrl), "NTLM", new NetworkCredential(userName, password));
clientContext.Credentials = myCache;
List documentLibrary = clientContext.Web.Lists.GetByTitle(documentLibraryName);
clientContext.Load(documentLibrary);
clientContext.ExecuteQuery(); 

byte[] bFile = System.IO.File.ReadAllBytes(filePath);
FileCreationInformation file = new FileCreationInformation();
file.Content = bFile;
file.Url = url;
file.Overwrite = true;
Microsoft.SharePoint.Client.File newFile = documentLibrary.RootFolder.Files.Add(file);
clientContext.Load(newFile);
clientContext.ExecuteQuery();

I am using SharePoint.Client.dll of version 14.0.0.0 so can't use methods provided for SP2013.

When I try to upload my file it throws me following exception

The remote server returned an error: (400) Bad Request

I have gone through

All the setting specified in this links are already implemented. But still the error is being thrown.

Initially I was not able to upload the file using GUI too. But after making changes I am now able to upload 40MB file through UI. But not from CSOM (C#) code.

Please provide suggestion what I should configure additionally to get it resolved.

Edits

I also want to update the document property at the time of upload. Currently I am doing this with following code:

newFile.ListItemAllFields[internalNames-1] = values-1;
newFile.ListItemAllFields[internalNames-2] = values-2;
newFile.ListItemAllFields.Update();
clientContext.ExecuteQuery();

Is this possible with SaveBinaryDirect() in the same call?

Reset to default

you should be using some other method that bypasses the executQuery. I think its got a set timeout and max 2mb file limit.

use SaveBinaryDirect with filestream.

https://msdn.microsoft.com/en-us/library/microsoft.sharepoint.client.file.savebinarydirect(v=office.14)

example function to call:

public void SaveBinaryDirect(ClientContext ctx, string libraryName, string filePath)
        {
            Web web = ctx.Web;
            // Ensure that the target library exists. Create it if it is missing.
            if (!LibraryExists(ctx, web, libraryName))
            {
                CreateLibrary(ctx, web, libraryName);
            }

            using (FileStream fs = new FileStream(filePath, FileMode.Open))
            {
                Microsoft.SharePoint.Client.File.SaveBinaryDirect(ctx, string.Format("/{0}/{1}", libraryName, System.IO.Path.GetFileName(filePath)), fs, true);
            }

        }
