difference between backward slash and forward slash in file source

[FlorisDevreese]

The result of nuget pack differs depending on if you use forward slash / or backward slash \ in the .nuspec file.

Details

Used nuget.exe Version: 4.9.3.5777 on Windows 10 v1709 (16299.699)

Repro

1. Create folder layout

testPackage.nuspec
sources/
    file.txt

2. Use this nuspec

<?xml version="1.0"?>
<package xmlns="http://schemas.microsoft.com/packaging/2010/07/nuspec.xsd">
  <metadata>
    <id>testPackage</id>
    <version>1.0.0</version>
    <authors>name</authors>
    <description>description</description>
  </metadata>
  <files>
    <file src="sources/**" target="forward/"/>
    <file src="sources\**" target="backward/"/>
  </files>
</package>

3. nuget.exe pack testPackage.nuspec

Expected result

<nupkg>/
    backward/
        file.txt
    forward/
        file.txt

Actual result

<nupkg>/
    backward/
        file.txt
    forward/
        sources/
            file.txt

Notes

• I could be wrong, but I don't think this is works as designed
• This chould be related to Cross-platform glob pattern and path issues #3584
