Visual Studio XML summary comment on single line

Question

In Visual Studio, how do I change the default XML summary comment snippet from three lines to one line?

Currently it provides this snippet when I type ///

Answer 1

You can manually format the comment however you like it, as long as it remains valid xml.

The cheapest approach might be to disable the automatic comment-building action in Visual Studio (Tools > Options > Text Editor > C# > Generate XML Documentation comments for ///) and use a code snippet to insert ///

.

If you want the default format to be a single line, and/or help to keep the format tidy and readable, my addin Atomineer Pro Documentation may also be of interest. Among the many options is one to use a compact 1-line format for any comment that is short enough to fit on a single line. It is specifically designed to do this, so it may work better for your needs.

A final suggestion is that there are several other add-ins (Resharper, etc) that can generate simple boilerplate xml doc-comments - I believe some of these addins can be configured to use a particular text snippet. If you already have such an addin, it may be that yours can be adjusted to provide the one-line format you require, in a slightly more advanced manner than is possible with the basic Visual Studio tweak suggested above.
