SOS Debugging Extensions for Microsoft.NET.CoreRuntime

▲

While trying to track down a fatal null pointer language exceptions (c000027b) in a UWP C#/XAML store project with WinDbg, I cannot get to the CLR Exception object because of a missing SOS debugging extention for Microsoft.NET.CoreRuntime. I was unable to locate a matching sos.dll. What am I missing?

Note: The app crash is reproducible, but only happens when not debugging. So running the project under the Visual Studio debugger is unfortunately not a solutions in this case.

Thank you magicandre1981 and Andrew Richards for your help! With the CLRStack provided by Andrew Richards I was able to narrow down the problematic part to a single method. After an initial workaround based on catching a generic exception, further investigation showed that a Uri passed to the BitmapImage constructor BitmapImage(Uri) cannot reliably be retrieved back via the UriSource property.

A person more knowledgeable about the internal caching mechanism of BitmapImage could may be shed some light on this behaviour. If the BitmapImage internal caching comes into operation, accessing BitmapImage.UriSource.OriginalString may apparently raise a null pointer exception, even if BitmapImage(Uri) was used with a valid Uri to construct the BitmapImage object.

My amended serialisation method does no longer access BitmapImage.UriSource.OriginalString, but instead maintains that Uri with an additional private property of the CastImage class. Problem solved.

/// <summary>
/// Translates the current instance into a JsonObject.
/// </summary>
/// <returns>The current instance as a JsonObject.</returns>
public JsonObject Serialise()
{
    JsonObject jsonObject = new JsonObject();

    jsonObject.Add("Number", this.number.HasValue ? JsonValue.CreateNumberValue(this.number.Value) : JsonValue.CreateNullValue());
    jsonObject.Add("Category", (!string.IsNullOrEmpty(this.category)) ? JsonValue.CreateStringValue(this.category) : JsonValue.CreateNullValue());
    jsonObject.Add("Comment", (!string.IsNullOrEmpty(this.comment)) ? JsonValue.CreateStringValue(this.comment) : JsonValue.CreateNullValue());

    if (this.performer != null)
    {
        jsonObject.Add("Performer", this.performer.Serialise());
    }
    else
    {
        jsonObject.Add("Performer", JsonValue.CreateNullValue());
    }

    if (this.castImages != null)
    {
        jsonObject.Add("CastImages", this.castImages.Serialise());
    }
    else
    {
        jsonObject.Add("CastImages", JsonValue.CreateNullValue());
    }

    jsonObject.Add("CastClip", this.castClip != null ? JsonValue.CreateStringValue(this.castClip.ToString()) : JsonValue.CreateNullValue());


    return jsonObject;
}

ok, with the help of the Windbg Extension PDE.dll from Andrew Richards, after running !PDE.dpx -dse to shows all Stowed Exceptions (those 0xC000027B exceptions) I see 5 Stowed Exceptions:
