Just thought I'd throw my two cents into this old topic, as Martin's answer didn't quite have enough detail for me in regards to the solution files.
Ranorex IDE generates 3 solution files:
- MyProject.rxsln
MyProject.sln
MyProject_2010.sln
The .rxsln is Ranorex's own solution file format, and is what you should use when opening in the Ranorex IDE. Whenever you make changes to referenced projects, it will automatically update the related "MyProject.sln" and "MyProject_2010.sln".
So what are the other two for?
You can use Visual Studio to also edit, compile and even run the test suite projects (it will still consume a license for execution), although you won't get the embedded report viewing.
The "
MyProject.sln" is a Visual Studio 2008 compatible version.
The "
MyProject_2010.sln" is a Visual Studio 2010 onwards compatible version, including 2012 and 2013.
It's a case of Microsoft tinkering with their solution file layouts and they kept changing it from VS 2005, 2008 and 2010. It seems they've finally settled on the format from 2010, so this is the one to use if you have a newer version of Visual Studio installed.
An important note: If you do have staff who like to use Visual Studio to do their work, then they need to remember that Visual Studio doesn't reflect project add/removal/rename in the other solution files.
