Question

My problem is t

Answer 1

I use VS 2010 and my XML documentation is regenerated correctly on each build.

Even a simple rebuild will force the file to update. If you modify the class description and rebuild, you should also get XML with the updated description.

Answer 2

I also experienced this issue in Visual Studio 2015 Update 3.

I enabled Diagnostic MSBuild project build output verbosity in Visual Studio's Tools > Options and discovered that it was copying a version of the XML documentation file from another project's output directory.

Only after I did a Clean on all the solution's build configurations and then re-built my project, did the XML documentation file get regenerated and reflect the latest XML comments in my code.

Answer 3

I faced this exact problem and I couldn't figure it out for the life of me.

It turned out that I had a old version of the .xml file in a folder where I saved dlls used in the project. So visual studio was just copying that xml file instead of generating a new one. (This was on Visual Studio Communtiy 2017)

So check if you have a old version of the .xml file in any of the same directories as any of your referenced dlls.
