Studio 2015 beta 1 was recently released and you can find more information about this release by going here. As an OpenExchange developer the next question which probably pops is if my Studio 2014 plugin will work on the new Studio version. The short answer is no and this is because Studio 2015 is build on a newer .NET version and there is a new plugin location from where Studio 2015 loads your plugins. There 3 main things that must be done in order to have your plugin ready for Studio 2015: Besides the new .NET Framework you also need to reference the new Studio API assemblies which have the same name as before is just that they are located in the Studio 2015 install folder. So here are the exact steps you to recompile your plugin:

1. .Net 4.5.2 is not working with Visual Studio 2010 so you need to upgrade to Visual Studio 2012 or Visual Studio 2013. My recommendation is to go with Visual Studio 2013 because of many reasons but the most important is the fact that Visual Studio 2013 has a community version which is completely free and has the exact same features as the professional version. More on community version here. 

1. Recompile plugin against Studio 2015 assemblies

As I mentioned in my introduction Studio 2015 is build against a newer version of Microsoft .NET, to be more precise is .Net Framework 4.5.2. This means that Studio 2014 plugins will not work since they are build against .Net Framework 4 and this is because you can have backward compatibility but there is no way to have future compatibility.  

2. Studio 2015 plugin install location

Coming soon.

3. Submint new plugin version on OpenExchange
