Attempt to obtain projects that begin with a particular word , but I get the following error: "The 'StartsWith' member cannot be used in the expression."
ProjectContext projContext = new ProjectContext(urlPWA);
projContext.Credentials = new SharePointOnlineCredentials(user,passwordSecurity);
projContext.Load(projContext.Projects, c => c.Where(p => p.Name.StartsWith(name, true, new CultureInfo("es-ES"))).IncludeWithDefaultProperties(f => f.Name, f => f.Tasks, f => f.ProjectResources, f => f.Owner.UserId, f => f.CheckedOutBy.UserId));
projContext.ExecuteQuery();
