an error message "Administration service is stopped. Start the Microsoft SharePoint Foundation Administration 2010 service in order for the operation to continue." is shown below:

Since I do not start the administration service, I go to start the service by going to Administrative Tools -> Services. Then , I click SharePoint 2010 Administration and start it.

REST: CRUD authentication in C#

DefaultCredentials:
"The DefaultCredentials property applies only to NTLM, negotiate, and Kerberos-based authentication. DefaultCredentials represents the system credentials for the current security context in which the application is running. For a client-side application, these are usually the Windows credentials (user name, password, and domain) of the user running the application. For ASP.NET applications, the default credentials are the user credentials of the logged-in user, or the user being impersonated."

DefaultCredential in C#

context.Credentials = CredentialCache.DefaultCredentials;
projectsBindingSource.DataSource = context.Projects;

If you don't want to use current window credentials, you can using the following code:

ICredentials cache = new NetworkCredential("username", "password", "domain");
context.Credentials = cache;

SharePoint foundation: incoming emails do not trigger workflows

"This problem occurs because a security fix in Windows SharePoint Services 3.0 SP1 prevents declarative workflows from starting automatically under the system account. E-mail enabled list items are always created under the system account."


By default, sharepoint foundation will not trigger the workflow by emailed items. In order to enable this property, you need to type some commands

1. "stsadm -o getproperty -pn declarativeworkflowautostartonemailenabled"

2. "stsadm -o setproperty -pn declarativeworkflowautostartonemailenabled -pv true"
