As you can see, one the Deactivation, I have called the following methods:

• DeleteImagesJsCssFolders(rootweb);

• ChangeSiteMaster(rootweb, defaultMasterPage);

• DeleteFolders(rootweb, masterPagesfolder);

• DeleteFolders(rootweb, pageLayoutsFolder);

DeleteImageJsCssFolder

As we need to update the CSS, images and JavaScript on activation and remove them when we remove our solution, the code will remove all used CSS, images and JavaScript which the solution used. Code is like below:

private void DeleteImagesJsCssFolders(SPWeb rootweb)
{
SPFolder folder;
string imagesPath = rootweb.Url + publishingImagesPath + publishingImagesFolder;
folder = rootweb.GetFolder(imagesPath);
if (folder != null && folder.ItemCount > 0)
{
folder.Delete();
}

string styleLibraryPath = rootweb.Url + stylePath + styleFolder;
folder = rootweb.GetFolder(styleLibraryPath);
if (folder != null && folder.ItemCount > 0)
{
folder.Delete();
}

string jsLibraryPath = rootweb.Url + jsPath + jsFolder;
folder = rootweb.GetFolder(jsLibraryPath);
if (folder != null && folder.ItemCount > 0)
{
folder.Delete();
}
}

ChangeSiteMaster

On retraction, we need to reset the master page to the original state, so we have to implement the logic so that existing master page will reset to Sharepoint site. The code should be like:

/// <summary>
/// Changes site master page to default
/// </summary>
/// <param name="web">root web of the site</param>
internal void ChangeSiteMaster(SPWeb web, string defaultMasterPage)
{
using (SPWeb currweb = web)
{
currweb.CustomMasterUrl = GetUrlWithTrailingSlash(currweb.ServerRelativeUrl) + defaultMasterPage;
currweb.Update();
foreach (SPWeb childweb in currweb.Webs)
{
ChangeSiteMaster(childweb, defaultMasterPage);
childweb.Dispose();
}
}
}

DeleteFolder

Finally we need to remove the folder which contains Master Pages and Page layouts. Here is the code for that:

/// <summary>
/// Deletes folder from the master page gallery
/// </summary>
/// <param name="rootweb">rootweb of the site</param>
internal void DeleteFolders(SPWeb rootweb, string folderName)
{
//Removing the master pages and page layouts folder.
SPList galleryList = rootweb.GetCatalog(SPListTemplateType.MasterPageCatalog);
SPFolderCollection subfolders = galleryList.RootFolder.SubFolders;
if (subfolders != null && subfolders.Count > 0)
{
SPFolder folder = subfolders.OfType<SPFolder>().ToList().Find(i => string.Equals(i.Name.Replace(" ", ""),
folderName.Replace(" ", ""),
StringComparison.CurrentCultureIgnoreCase));
if (folder != null)
{
folder.Delete();
galleryList.Update();
}
}
}

That's all. We are ready with our Branding Solution.

Summary

As this solution structure is standard and more flexible, it is ready for use for your development purpose. This will save a lot of your development effort and provide a standard solution structure which you can use for multiple applications in Sharepoint.
