Just create an extension for the StringBuilder class:

Public Module Extensions
    <Extension()>
    Public Sub AppendFormatWithNewLine(ByRef sb As System.Text.StringBuilder, ByVal format As String, ParamArray values() As Object)
        sb.AppendLine(String.Format(format, values))
    End Sub
End Module

Use StringBuilder's append line built-in functions:

StringBuilder sb = new StringBuilder();
sb.AppendLine("First line");
sb.AppendLine("Second line");
sb.AppendLine("Third line");

Output

First line
Second line
Third line

I would make use of the Environment.NewLine property.

Something like:

StringBuilder sb = new StringBuilder();
sb.AppendFormat("Foo{0}Bar", Environment.NewLine);
string s = sb.ToString();

Or

StringBuilder sb = new StringBuilder();
sb.Append("Foo");
sb.Append("Foo2");
sb.Append(Environment.NewLine);
sb.Append("Bar");
string s = sb.ToString();

If you wish to have a new line after each append, you can have a look at Ben Voigt's answer.

StringBuilder sb = new StringBuilder();

You can use sb.AppendLine() or sb.Append(Environment.NewLine);

For multiple lines the best way I find is to do this:

        IEnumerable<string> lines = new List<string>
        {
            string.Format("{{ line with formatting... {0} }}", id),
            "line 2",
            "line 3"
        };
        StringBuilder sb = new StringBuilder();
        foreach(var line in lines)
            sb.AppendLine(line);

In this way you don't have to clutter the screen with the Environment.NewLine or AppendLine() repeated multiple times. It will also be less error prone than having to remember to type them.
