The "ExpandPriContent" task failed unexpectedly. Cannot access a disposed object.

Describe the bug

I'm often experiencing the following bug when compiling. Usually it works, but once hitting this, I have to restart Visual Studio. Looks to be a failure in the telemetry code, preventing me from compiling. I don't have a consistent repro, but have observed it with both v1.0.0 and v1.1.4:

Steps to reproduce the bug

No specific repro. Happens after building a maui app over and over. I've observed it on two different PCs, one running Win10 and the other Win11. VS version was 17.3.1 on both.

Expected behavior

No response

Screenshots

No response

NuGet package version

1.1.4

Packaging type

Packaged (MSIX)

Windows version

Windows 11 version 21H2 (22000)

IDE

Visual Studio 2022

Additional context

Visual Studio 17.3.1. Looks very similar to Xamarin telemetry issue (that was supposed to be fixed in 17.3.1 but I'm still occasionally observing that one too). See https://developercommunity.visualstudio.com/t/Unexpecter-error-of-task-Xamarin-Teleme/10096527

Had a similar error today building an Xamarin Forms UWP app with VS 17.3.4 I think. Updating to 17.3.5 fixed, but it seemed random.

@rohanp-msft is there a known workaround for this without having to restart the VS? Is there anything we could help with to resolve this issue? Happens quite frequently when there is a change in xaml files.

[rohanp-msft]

@LadderLogic AFAIK, there isn't another workaround (rebuilding the solution might be one, though that's just as bad). This was postponed due to some higher priority work. I will be able to look at this in a week's time. We apologize for the delay.

[rohanp-msft]

@LadderLogic Hi Nanda, do you have a repro of this?

This is unrelated other than this exception also occurs in the same task. Somehow, the PRI XML dump was invalid here. Anyway, it looks like the problem is gone for you after the upgrade.

@LadderLogic Hi Nanda, do you have a repro of this?

@rohanp-msft, it's part of a large solution with multiple projects referencing the same xaml control library, but I'll try to make a small repo soon.

[rohanp-msft]

Since there haven't been any recent reports of this issue, we expect this is addressed by an update to VS. I am closing this issue. If it is reported again on latest VS, etc., we will revisit it.

[ADD-David-Antolin]

Yes, it is still happening in Visual Studio 2022 17.5.0 and WindowsAppsSDK 1.2.221109.1.

@soroshsabz The owners have changed (see the current Assignees of this issue). I notified them when you commented. @loneursid can provide the triage results.

FYI - this seems to have helped others with the System.ObjectDisposedException: for VS builds: >set MSBUILDDISABLENODEREUSE=1 for MSBuilds: (above) or >msbuild /nodeReuse:false ...

[DominikErnst]

Same here! Solutions?

[Scottj1s]

We have root caused this issue to a bug in the MSIX packaging support logic in Windows App SDK and will have a fix available soon. There is no workaround.

I see the issue once in a while when building Windows Runtime Components which are C++ WinUI3 Desktop type components. I am using the latest everything VS2022 17.96, Latest Windows App SDK etc. When it happens it is after working for a while and normally a clean rebuild works to resolve but more recently that is failing. This is starting to become a productivity issue.

I have a suspicion that files might get left open which also may be why Clean fails once in a while. Which also may be why closing VS and opening again solves the issue.

[Scottj1s]

Here's an explanation of the fix (thanks, @evelynwu-msft), which will be available in WinAppSDK 1.6:

The Single-project MSIX Packaging build tasks were, by default, directly using VS's default telemetry session. After they finished running, they would dispose this default session. Later, if some other build task in the same MSBuild process accessed the now-disposed default session, an exception would be raised.
