I'm in the process of converting a VS 2010 Azure solution to VS 2013 (staying with. Net 4.0). We are using the Reactive library that was installed via nuget. When I tried to build the converted solution in VS 2013 the source file that uses the Reactive.Observable
class would not compile. It threw a CS0234 error for the 'using' statement 'using System.Reactive.Linq;'.
The odd thing is the editor is underlining the line in blue, not red. The four Reactive assemblies ARE listed under the project references in the solution explorer. I can open them up in the object browser so I know the files really are there.
If I remove the 'using' statements from the source file, I can go down to the line that references the Observable object (which is now underlined in red), right-click and select Resolve. It shows the correct 'using' statement to use, I click it and it inserts
that statement at the beginning of the file as expected.
So I save the file and try to compile it. The compile fails (same CS0234 error) and the using statement is underlined in blue again.
I created a simple console app targeting 4.0, added the Reactive package from nuget and tried a similar call which worked just fine.
Any ideas what is missing? Could migrating from 2010 to 2013 broken something?
