Information

It looks like this is a bug in the Windows OS that went out beginning of March related to deploying the WinAppSDK runtime that's packaged with the WinAppSDK nuget. There is a planned OS update in the near future that will resolve this issue.

Workaround

2 available workarounds

1. Manually install the runtime that corresponds to the version you are using https://learn.microsoft.com/en-us/windows/apps/windows-app-sdk/downloads

   • MAUI 8.0.20+ is 1.5.2
   • MAUI 8.0.10-8.0.14 is 1.4.2

2. Set the project property in your MAUI app project. Ideally workaround 1 works for you. Disabling the DeploymentManager will cause some features of WinUI to no longer work.

   <PropertyGroup>
       <WindowsAppSdkDeploymentManagerInitialize>false</WindowsAppSdkDeploymentManagerInitialize>
   </PropertyGroup>

Description

The program fails to compile after version 8.0.20 of the Microsoft.Maui.Controls and Microsoft.Maui.Controls.Compatibility packages.

Steps to Reproduce

1.Use visual studio 2022 to create a new MAUI project file.
2.Compile and run it on Windows platform, and the program starts normally.

(The Nuget package version used is shown in the figure)

4.Upgrade the nuget package version to 8.0.20.

5.Compile the program again and find that the program cannot run normally.

The exception information is as follows:
引发的异常:“System.Runtime.InteropServices.COMException”(位于 WinRT.Runtime.dll 中) WinRT 信息: 找不到元素。
