Paket Case-Sensitivity when creating package references

Description

SDKRepro.zip

This repo contains two projects: MySDK and MyClient.
MyClient has a project reference to MySDK.

Expected behaviour:

When creating nuget packages using the provided pack command-line, two packages should be created and MyClient should have a dependency on the MySDK package.

paket.exe pack nuget --build-config Debug --build-platform "AnyCPU" --version 1.0.0

MyClient.nuspec inside MyClient-1.0.0.nupkg should look like this:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<package xmlns="http://schemas.microsoft.com/packaging/2011/10/nuspec.xsd">
  <metadata>
    <id>MyClient</id>
    <version>1.0.0</version>
    <title>MyClient</title>
    <authors>MyCompany</authors>
    <description>MyClient program.</description>
    <dependencies>
      <dependency id="MySDK" version="1.0.0" />
    </dependencies>
  </metadata>
</package>

Actual behaviour

The dependency is not found:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<package xmlns="http://schemas.microsoft.com/packaging/2011/10/nuspec.xsd">
  <metadata>
    <id>MyClient</id>
    <version>1.0.0</version>
    <title>MyClient</title>
    <authors>MyCompany</authors>
    <description>MyClient program.</description>
  </metadata>
</package>

This behaviour seems to depend on casing of the MySdk directory:

• If the directory is renamed to MySDK, the dependency is found
• If the directory name is Pascal case (MySdk), the dependency is not found

Tested on Windows 7 on an NTFS file system

Known workarounds

Be careful with casing.

Start with SDKRepro.zip and reproduce the issue using paket.exe pack nuget --build-config Debug --build-platform "AnyCPU" --version 1.0.0. Compare the generated MyClient.nuspec when the MySDK directory uses MySDK versus MySdk; done means the MyClient package contains a MySDK dependency regardless of directory casing.
