When setting the icon of the project tree using IProjectTreePropertiesProvider the Icon property doesn’t change the icon that is showned. It’s always the default C# proect.

Here’s the code I’m using:

[Export(typeof(IProjectTreePropertiesProvider))]
[AppliesTo(NanoCSharpProjectUnconfigured.UniqueCapability)]
internal class ProjectTreePropertiesProvider : IProjectTreePropertiesProvider
{
    /// <summary>
    /// Calculates new property values for each node in the project tree.
    /// </summary>
    /// <param name="propertyContext">Context information that can be used for the calculation.</param>
    /// <param name="propertyValues">Values calculated so far for the current node by lower priority tree properties providers.</param>
    public void CalculatePropertyValues(
        IProjectTreeCustomizablePropertyContext propertyContext,
        IProjectTreeCustomizablePropertyValues propertyValues)
    {
        // set the icon for the root project node
        if (propertyValues.Flags.Contains(ProjectTreeFlags.Common.ProjectRoot))
        {
            propertyValues.Icon = KnownMonikers.AbstractCube.ToProjectSystemType(); ;// NanoFrameworkMonikers.NanoFrameworkProject.ToProjectSystemType();
            propertyValues.ExpandedIcon = NanoFrameworkMonikers.NanoFrameworkProject.ToProjectSystemType();
        }
    }
}

To rule out any issues with the icon format on my resources, I’ve momentarily replaced it with one of VS stock icons, as can be seen from the above. The result is the same.

The ExpandedIcon property does work.

Attaching screenshots of a project tree expanded and colapsed for illustration.

Worth noting that this happens in both VS2017 and VS2019.

Hi,

Any update on this?

Glad to hear you got it working. I agree the comment is confusing. Take a look at https://github.com/microsoft/VSProjectSystem/pull/327 and see if you find it an improvement.

Thanks again for your feedback and helping to improve the project system!
