List all Defined MSBuild Variables - Equivalent to set

Is there a way to list all defined variables in an executing MSBuild project?

I'm trying to figure out exactly what paths and variables are set (to pass into WiX), and it's difficult to debug everything. Essentially, I would like something equivelent to running set at the command line. Example:

C:\Users\dsokol>set
ALLUSERSP开发者_运维百科ROFILE=C:\ProgramData
APPDATA=C:\Users\dsokol\AppData\Roaming
asl.log=Destination=file
CLASSPATH=.;C:\Program Files (x86)\QuickTime\QTSystem\QTJava.zip
CommonProgramFiles=C:\Program Files\Common Files
CommonProgramFiles(x86)=C:\Program Files (x86)\Common Files
...

Except that I would like it to list out all of the MSBuild variables (such as Target, OutDir?, and all the crap I've defined in the top of the XML file. Ideally:

$(OutDir)="C:\MyOutDir\bin"
$(ProductVersion)="6.1.0"
$(Platform)="Win32"

Does such a thing exist?

Have you tried running msbuild with with /v:diag command line option? This prints out all of the properties which includes the environment variables and the properties that have been set.

---

I bingoogled everywhere and couldn't find anything about existing code that does it, so I came with my own approach.

First - you build a project with msbuild using the preprocess/pp parameter to put all the linked projects to a single file.

C:\Program Files (x86)\MSBuild\14.0\Bin\MSBuild.exe" /verbosity:detailed /fl /p:Configuration=Debug /p:Platform=x86 MyApp.csproj /pp:flatproject.proj >detailedlog.txt

That already gives you a single project xml file with all properties that were set (perhaps except the environment variables or the ones passed with the /p parameter to msbuild or perhaps some others that might be set otherwise). For me that's over 800 properties. Now if you want to compile a list in alphabetical order - you could do that with a little bit of code - in my case C# and XAML:

<Window x:Class="WpfApplication4.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:WpfApplication4"
        mc:Ignorable="d"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <TextBox
            x:Name="tb"
            VerticalAlignment="Stretch"
            HorizontalScrollBarVisibility="Visible"
            VerticalScrollBarVisibility="Visible"/>
    </Grid>
</Window>

C# bit:

public partial class MainWindow : Window
{
    Dictionary<string,string> properties = new Dictionary<string, string>();

    public MainWindow()
    {
        InitializeComponent();
        var xml = new XmlDocument();
        xml.LoadXml(File.ReadAllText(@"c:\git\Photos\Photos\AppStubCS\AppStubCS.Windows\x.prop"));
        PopulateProperties(xml);
        SortAndOutput();
    }

    private void SortAndOutput()
    {
        var sb = new StringBuilder();
        foreach (var kvp in properties.OrderBy(kvp => kvp.Key))
        {
            sb.AppendFormat("{0}: {1}\r\n", kvp.Key, kvp.Value);
        }
        this.tb.Text = sb.ToString();
    }

    private void PopulateProperties(XmlNode xml)
    {
        if (xml.Name == "PropertyGroup")
        {
            foreach (var childNode in xml.ChildNodes.OfType<XmlElement>())
            {
                var name = childNode.Name;
                var val = childNode.InnerText;

                if (properties.ContainsKey(name))
                {
                    properties[name] = val;
                }
                else
                {
                    properties.Add(name, val);
                }
            }
        }
        else
        {
            foreach (var childNode in xml.ChildNodes.OfType<XmlElement>())
            {
                PopulateProperties(childNode);
            }
        }
    }
}

For some reason, /v:diagnostic did not dump the environment variables for me.

I tried some stuff, and then the sort-of obvious simple thing worked. Try:

<Exec Command='set' />

You might want to try Debugging MSBuild script with VisualStudio. I haven't tried it, but it seems like it could allow you to step through a script and also list variables.

---

I know this question is a little old and I'm not sure if there's actually a way to enumerate all defined property names in MSBuild parlance (I'm not aware of one), but I would recommend using the /bl (/binlog[:filename]) switch and loading the resulting binary log in the MSBuild Binary and Structured Log Viewer which will not only tell you every property defined and its value, but also show what the values were as each target or task is called throughout the build. This tool has been incredibly useful for learning the inner workings and finding appropriate extension points when customizing MSBuild and can even take you to the line of MSBuild xml that was being executed when you double click on events in the log. There's also a Visual Studio extension mentioned on the site linked that can be used to troubleshoot design time builds (when VS calls MSBuild for things like XAML previews, etc.)
