SharePoint Dragons

The SharePoint 2010 Best Practice Overview page just underwent a major overhaul and here’s the result: http://social.technet.microsoft.com/wiki/contents/articles/8666.sharepoint-2010-best-practices-en-us.aspx

The SPUtility.SendEmail() method has a limit of the max number of characters on a single line: 2048. However, you can divide the message body in chunks of several lines, thereby circumventing the maximum: http://social.msdn.microsoft.com/Forums/en/sharepointdevelopment/thread/a0292b6b-e412-4ccb-910d-1df90f90d5d9. Alternatively, you can send emails directly, using code like this:

System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
message.From = new System.Net.Mail.MailAddress(objWeb.Site.WebApplication.OutboundMailSenderAddress);
message.To.Add(new System.Net.Mail.MailAddress(objTcnlSite.AcmaEmail));
message.Subject = Subject;
message.Body = Body;
message.IsBodyHtml = true;
System.Net.Mail.SmtpClient smtpClient = new System.Net.Mail.SmtpClient(objWeb.Site.WebApplication.OutboundMailServiceInstance.Server.Address);
smtpClient.UseDefaultCredentials = true;
smtpClient.Send(message);
smtpClient = null;
message.Dispose();

The Asset vs Picture library TechNet Wiki article has been revised. You can find the latest version here: http://social.technet.microsoft.com/wiki/contents/articles/8110.sharepoint-2010-best-practices-asset-vs-picture-library-en-us.aspx

You can use the logging database to store ULS logs, check http://www.oriolardevol.com/Article/Details/36. See http://www.oriolardevol.com/Article/Details/Sharepoint%20Logging%20database%20-%20ULS%20Trace%20tables,%20how%20they%20work for info on how it is stored. Consolidated storage and access to the ULS is a huge benefit, and also makes querying it a lot easier. In addition, the logging db also contains other useful info such as DMVs and performance counters:http://sharepoint.microsoft.com/blogs/fromthefield/Lists/Posts/Post.aspx?ID=124

The TechNet Wiki page about dealing with performance issues has been updated: http://social.technet.microsoft.com/wiki/contents/articles/7926.sharepoint-2010-tips-for-dealing-with-performance-issues.aspx
