NewLine in object summary

You want to use some thing like this

/// <summary> 
/// Your Main comment 
/// <para>This is line 1</para> 
/// <para>This is line 2</para> 
/// </summary> 
public bool TestLine { get; set; }

This may be an old thread but I was searching for an anwser while using Visual Studio 2019. I wanted paragraph and lines breaks. The following works well for me:

/// <summary>
/// <para>parameter name="guidType" options:</para>
/// <br>0 = SequentialAsString</br>
/// <br>1 = SequentialAsBinary</br>
/// <br>2 = SequentialAtEnd</br>
/// </summary>

Produces the following:

parameter name="guidType" options:

0 = SequentialAsString
1 = SequentialAsBinary
2 = SequentialAtEnd

Yes:

/// <summary> 
/// Main comment 
/// <para>Line 1</para> 
/// <para>Line 2</para> 
/// </summary> 
public bool TestLine { get; set; }
