nuget spec dependencies, get latest version?

nuget, nuspec, specifications, versioning

Solution

As of Nuget 2.8 you can add the following attribute to your nuget.config

<configuration>
    <config> 
        <add key="dependencyversion" value="Highest" /> 
    </config>
</configuration>

When resolving your packages, the latest version of that package will be resolved. Other attributes include HighestMinor, HighestPatch and lowest (based on semantic versioning)

Problem

In the nuspec versioning docs I see ``` 1.0 = 1.0 ≤ x (,1.0] = x ≤ 1.0 (,1.0) = x < 1.0 [1.0] = x == 1.0 (1.0) = invalid (1.0,) = 1.0 < x (1.0,2.0) = 1.0 < x < 2.0 [1.0,2.0] = 1.0 ≤ x ≤ 2.0 empty = latest version. ``` I have a `packages.config` that looks like this ``` <packages> <package id="psake" version="4.2.0.1" /> </packages> ``` and I would like to change the version to "latest". I've tried both ``` <packages> <package id="psake" version="" /> </packages> ``` and ``` <packages> <package id="psake" /> </packages> ``` but both result in `Unable to parse version value '' from 'packages.config'.` I am using Nuget.exe 2.8.2
