VS 2015 RTM - csproj xml node Project\ProjectExtensions\VisualStudio\UserProperties attribute order differs based on machine that saves file

[bbarry]

When 2 or more people make changes to a project that has multiple properties stored on the UserProperties tag, the order of the properties on the attribute appears to depend on order that code runs to set the attributes.

I have several csproj files with

<ProjectExtensions>
  <VisualStudio>
    <UserProperties 
      PingPoet_SlashDocs_DocCommentIncludeFileBasePath="...removed..." 
      PingPoet_SlashDocs_SlashDocPathReplacePattern="...removed..." 
      PingPoet_SlashDocs_SlashDocPathMatchPattern="^...removed...$" />
  </VisualStudio>
</ProjectExtensions>

(the node is on one line).

With the project file in source control and multiple developers, this line changes every time a dev makes any change to the file. This results in merge conflicts very often as in this case there are 6 possible ways to have that line.
