[Question] DataGrid and System.Reflection.MissingMetadataException: 'Windows.Foundation.IReference`1<Double>'

[omikhailov]

Hello!

I have the following problem: I changed hardware, installed the latest Windows updates and also updated the WCT and WinUI 2 packages, and now after starting the application in Release mode, it fails. In Debug mode with enabled Optimize Code and .Net Native Toolchain options, the following exception is thrown in GetXamlTypeByType() within XamlTypeInfo.g.cs :

System.Reflection.MissingMetadataException
  HResult=0x80131543
  Message=Windows.Foundation.IReference`1<Double>

    </Type>

  </Application>
</Directives>

... and adding

<Type Name="Windows.Foundation.IReference`1{Double}" Dynamic="Required All" />

does not fix it.

Is it some known issue with the DataGrid?

Here is the link to .zip file with the app code in case if somebody would need to reproduce the issue: https://1drv.ms/u/s!AhdSWUTnA1aPgjz3Mp8UNmITf-zv?e=LEaD2m I'm on Windows 10 Pro 19043.1237, Visual Studio 2019 16.11.3 and Ryzen 3600

Hello omikhailov, thank you for your interest in Windows Community Toolkit!

I have automatically added a "needs triage" label to help get things started. Our team will analyze and investigate the issue, and escalate it to the relevant team if possible.. Other community members may also answer the question and provide feedback 🙌

Hi @omikhailov the project looks a bit complex, can you point us to the project that should be run (you can also just attach zip files to issues directly usually)?

What specific versions of the Toolkit and WinUI are you using as there are various previews and stable releases available at the moment?

[omikhailov]

Hi, Michael!

Startup project is called Hamburger, and all projects within solution use Windows Community Toolkit 7.0.2 and WinUI 2.7

@Arlodotexe @XAML-Knight wonder if this repros for either of you? I don't think we've heard reports of this from anywhere else.

[michael-hawker]

Actually, just got a notification on another issue which appears to be very similar filed on the platform here: https://github.com/microsoft/microsoft-ui-xaml/issues/2545

@Sergio0694 do you remember context here? Did it go away targeting a newer platform version? @omikhailov have you tried updating to the latest SDK, Toolkit, and WinUI versions since?

[omikhailov]

@omikhailov have you tried updating to the latest SDK, Toolkit, and WinUI versions since?

Just tried and it didn't resolve the issue as well as updating Windows to 19044.1415

Confirming the runtime error in the Hamburger app.
