##[error]C:\Program Files\Microsoft Visual Studio\2022\Preview\MSBuild\Current\Bin\Microsoft.Common.CurrentVersion.targets(43,3): error MSB4011: "D:\a_work\1\s.packages\microsoft.dotnet.arcade.sdk\10.0.0-beta.25372.103\tools\BeforeCommonTargets.targets" cannot be imported again. It was already imported at "D:\a_work\1\s.packages\microsoft.dotnet.arcade.sdk\10.0.0-beta.25372.103\Sdk\Sdk.targets (13,3)". This is most likely a build authoring error. This subsequent import will be ignored. [D:\a_work\1\s\src\Installers\Windows\AspNetCoreModule-Setup\ANCMIISExpressV2\AncmIISExpressV2.wixproj]

This is because Arcade's sdk.targets imports that file: https://github.com/dotnet/arcade/blob/2586309f3f8553152e2d1d54612e9199975f9cd4/src/Microsoft.DotNet.Arcade.Sdk/sdk/Sdk.targets#L13

And so does Microsoft.Common.CurrentVersion.targets:

<Import Project="$(CustomBeforeMicrosoftCommonTargets)" Condition="'$(CustomBeforeMicrosoftCommonTargets)' != '' and Exists('$(CustomBeforeMicrosoftCommonTargets)')"/>

due to: https://github.com/dotnet/arcade/blob/2586309f3f8553152e2d1d54612e9199975f9cd4/src/Microsoft.DotNet.Arcade.Sdk/tools/Settings.props#L7

This makes me think that typically Microsoft.Common.CurrentVersion.targets would come before sdk.targets in the preprocessed file, but in this case it's the other way around. We're doing a bunch of weird custom import stuff here so that's not terribly surprising. Investigating

I see, the Wix sdk.targets imports Microsoft.Common.targets now:

<Import Project="$(MSBuildToolsPath)\Microsoft.Common.targets" />

Which causes Microsoft.Common.CurrentVersion.targets to get imported, which causes the double-import of BeforeCommonTargets.targets from Arcade. @NikolaMilosavljevic @joeloff did either of you guys run into this?

Nope, didn't run into that for the SDK

Take a look at the SDK PR - you should consider using the predefined system colors. These now work with high contrast themes, making the installer pass a number of accessibility tests that failed in v3
