I have researched the topic and discovered that:
- You can install vs2012/13 on the same machine running vs2010 sp1
- You can target .NET framework 4.0 for your current projects and run them locally
The problem arises when you deploy your websites to servers that do not have fixes to bugs in .NET 4.0 that were made when installing .NET framework 4.5 on the local machine.
My question is, what is the best way I can make sure I can do the following using the same machine:
- I can still run my old/current vs2010 sp1 projects without breaking locally or when deployed remotely
- I can create new solutions using vs2010 sp1 targeting the .NET4.0 framework safely
- I can create new solutions using vs2012/13
If I cannot have the scenario above, would using Visual Studio Online help? (I have not had much to read on Visual Studio Online) but just thought that it could be an alternative to the above?
