Are NuGet package names case-sensitive?

nuget Rx-Interfaces ~> 2.2
nuget NUnit ~> 2.6

Wrong casing, nunit:

$ paket update nuget nunit
Paket version 0.17.16.0
found: paket.dependencies

    - exploring NUnit 2.6.1
    - exploring Rx-Interfaces 2.2.2

Correct casing, NUnit:

$ paket update nuget NUnit
Paket version 0.17.16.0
found: paket.dependencies
Resolving packages:
  - fetching versions for NUnit
    - exploring NUnit 2.6.3
    - exploring Rx-Interfaces 2.2.2

nuget.exe doesn't care about casing, but we apparently do:

$ nuget install nunit
Installing 'NUnit 2.6.3'.
Successfully installed 'NUnit 2.6.3'.

BTW, paket add nuget machine.specifications works as well. We should

• have a consistent story regarding paket add nuget <name> and paket update nuget <name>
• write API-reported casing to the dependencies and lock files

$ paket add nuget machine.specifications
Paket version 0.17.16.0
found: paket.dependencies
Adding machine.specifications to paket.dependencies <-- incorrect casing!
Resolving packages:
    - exploring NUnit 2.6.3
    - exploring Rx-Interfaces 2.2.2
  - fetching versions for machine.specifications <-- incorrect casing
    - exploring machine.specifications 0.9.1 <-- again

Yes there are still some places where have to use the corrected version name.
