Had issues with the GWT designer tab not appearing.

Installed the GWT Designer GPE and the designer tab reappeared.

SharePoint 2013 Downloading a document library using C# and Microsoft.SharePoint.Client

References

using Microsoft.SharePoint.Client;
using Microsoft.SharePoint;
using SP = Microsoft.SharePoint.Client;
using System.IO;

Main program drive code

• Gets a list of documents from a document library
• Loops through the list of documents
• Checks if there is more than one version of the document
• Loops through the list of versions in a document library and calls downloadSharePointFile to download that version.

                        ListItemCollection collListItem = querySharePointList(list.Title);

                        foreach (ListItem oListItem in collListItem)

                        {                            

                            Console.WriteLine(string.Format("{0} - {1}", oListItem["FileLeafRef"], oListItem["FileRef"]));

                            context2013.Load(oListItem);

                            context2013.Load(oListItem.File);

                            context2013.Load(oListItem.File.Versions);

                            context2013.ExecuteQuery();

                            //if (oListItem.File.Versions.Count > 1)

                                //MessageBox.Show("More than one version");

                            if (oListItem.File.Versions.Count > 1)

                            {

                                foreach (FileVersion version in oListItem.File.Versions)

                                {

                                    Console.WriteLine(String.Format("Version no: {0} url - {1}", version.VersionLabel, version.Url));

                                    downloadSharePointFile(version.Url, oListItem["FileLeafRef"].ToString());

                                }

                            }

                            //downloadSharePointFile(oListItem["FileRef"].ToString(), oListItem["FileLeafRef"].ToString());

                        }

Query the document library for a list of all the documents in the document library

title - the name of the document library

        private ListItemCollection querySharePointList(string title)

        {

            SP.List oList = context2013.Web.Lists.GetByTitle(title);

            CamlQuery camlQuery = new CamlQuery();

            camlQuery.ViewXml = "5000";

            ListItemCollection collListItem = oList.GetItems(camlQuery);

            context2013.Load(collListItem);

            context2013.ExecuteQuery();

            return collListItem;

        }

Download the document from the document library

filename - url to the document

documentName - name of the document

        private void downloadSharePointFile(string filename, string documentName)

        {

            string baseUri = "base url of the sharepoint application";

            // Create a new WebClient instance.

            WebClient myWebClient = new WebClient();

            System.Net.NetworkCredential netCredential = new System.Net.NetworkCredential("username", "password", "domain name");

            myWebClient.Credentials = netCredential;

            // Concatenate the domain with the Web resource filename.

            // Download the Web resource and save it into the current filesystem folder.

            string fileUrl = baseUri  + "/" + filename;

            myWebClient.DownloadFile(fileUrl, @"c:\temp\" + documentName);

        }

Creating a new web in SharePoint 2010 using C# and Microsoft.SharePoint.Client;

Implementation

            // Starting with ClientContext, the constructor requires a URL to the server running SharePoint.
            ClientContext context2010 = new ClientContext("SharePoint URL");

            WebCreationInformation creation = new WebCreationInformation();
            creation.Url = "New web URL name";
            creation.Title = "New web title";
            Web newWeb = context2010.Web.Webs.Add(creation);

            // Retrieve the new web information.
            context2010.Load(newWeb, w => w.Title);
            context2010.ExecuteQuery();

            MessageBox.Show("Web created");

SharePoint 2010 - Uploading a document into a document library with C# and Microsoft.SharePoint

Still working with 2010 in 2016? Me too.

You need to reference these libraries:

using Microsoft.SharePoint;
using System.IO;

        private static void uploadDocument()
        {
            String fileToUpload = @"C:\Temp\Accessibility audit of SharePoint 2010 January 2013.docx";
            String sharePointSite = "SharePoint site URL";
            String documentLibraryName = "Name of document library";
            try
            {
                using (SPSite oSite = new SPSite(sharePointSite))
                {
                    using (SPWeb oWeb = oSite.OpenWeb())
                    {
                        if (!System.IO.File.Exists(fileToUpload))
                            throw new FileNotFoundException("File not found.", fileToUpload);

                        SPFolder myLibrary = oWeb.Folders[documentLibraryName];

                        // Prepare to upload
                        Boolean replaceExistingFiles = true;
                        String fileName = System.IO.Path.GetFileName(fileToUpload);
                        FileStream fileStream = System.IO.File.OpenRead(fileToUpload);

                        // Upload document
                        SPFile spfile = myLibrary.Files.Add(fileName, fileStream, replaceExistingFiles);
                        // 2/12/2013 12:15 PM
                        spfile.Item.Properties.Clear();
                        spfile.Update();

                        // Commit
                        myLibrary.Update();
                    }
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }

Type was not included in the set of types which can be serialized by this SerializationPolicy or its Class object could not be loaded. For security purposes, this type will not be serialized.

While working on a GWT application incorporating a SuggestBox and a custom suggestion oracle class I got stung by the following error:

"Type 'custom suggestion class' was not included in the set of types which can be serialized by this SerializationPolicy or its Class object could not be loaded. For security purposes, this type will not be serialised."

The solution to my particular problem was to move the custom suggestion class into the client side package (it needs to be on the client side).

The following blog post from "Developer Resource" had the answer to my problem : http://developer-resource.blogspot.com.au/2008/07/google-web-toolkit-suggest-box-rpc.html?showComment=1220955960000#c5951897759257003353

Decided to put a post up about this solution to the problem because it has a very faint web foot print, most other suggested fixes are about creating a empty constructor for your suggestion class.
