Repro steps

1. Ctrl + N in Visual Studio and select F# script

2. Add #r "nuget: ini-parser" to the file

   It's important to type this into the file instead of pasting from the clipboard.

3. Observe C:\Users\...\.nuget\packages

Expected behavior

Only ini-parser directory should appear.

Actual behavior

The following directories appear:

• in/1.0.0/
• ini/1.0.7/
• ini-parser/3.4.0/

Every package on nuget.org whose ID is a prefix of the desired package is downloaded.

Another example: I tried to use microsoft.powershell.5.1.referenceassemblies once. Here are the packages that got downloaded:

I have a bunch of packages in my NuGet cache directory that I never used (knowingly), but whose IDs are all prefixes of packages I did use:

• b
• in
• java
• javascript
• l
• lib
• me
• mi
• mic
• micro
• o
• op
• s

This also looks like this is the reason why it takes so long for IntelliSense to work for the package I try to use.
