UIAutomationClient.dll not found

[ms0713]

Issue Title

UIAutomationClient.dll is not found in Reference Assemblies folder for .Net Core 3.0 Preview

General

I want to use System.Windows.Automation in my .Net Core 3.0 console application. When I try to reference UIAutomationClient.dll, i did not find the same in Reference Assemblies folder for .Net Core 3.0. Rather UIAutomationClient.xml is available on following folder
Reference Assemblies/Microsoft/Framework/.NETFramework/v4.X

.Net Framework folders have this UIAutomationClient.dll. i.e. 4.8, 4.7.2 etc..

Am I looking at the wrong place or I need to do something different in .Net Core 3.0 application?

Project Type : .Net Core 3.0 Console Application
Required Namespace : System.Windows.Automation
Required Dll for Reference : UIAutomationClient.dll
Using VS 2019 version 16.3 Preview2
.Net Core SDK version 3.0 Preview8

@vatsan-madhavan - Any plans to bring automation to Core?

@ms0713, Are you using a WindowsDesktop SDK project (Use dotnet new wpf to see an example of one)?

You cant refer it in .Net Core Console Application. Thats limitation.

This is working. Thanks!

I installed the latest rc1. Have the same issue. Can't manually reference the assembly due to the following error:

Below is a portion of .csproj file:

<Project Sdk="Microsoft.NET.Sdk.WindowsDesktop">
  <PropertyGroup>
    <TargetFramework>netcoreapp3.0</TargetFramework>
    <AppendTargetFrameworkToOutputPath>false</AppendTargetFrameworkToOutputPath>
    <GenerateAssemblyInfo>false</GenerateAssemblyInfo>
 <Configurations>EndToEndWithFake;EndToEndWithReal;IntegrationWithFake;IntegrationWithReal</Configurations>
    <UseWpf>true</UseWpf>
  </PropertyGroup>

Can't manually reference the assembly

@godrose What do you mean by that, exactly?

Did you use Visual Studio's Reference Manager dialog to browse to the location of UIAutomation.dll reference assembly (for e.g., something like C:\Program Files\dotnet\packs\Microsoft.WindowsDesktop.App.Ref\3.0.0-rc2-19460-02\ref\netcoreapp3.0\UIAutomation.dll) and try to add that as a reference in your .NET Core WPF project - like this ?

If my guess is correct, then you can't do that.

All WPF assemblies are already implicitly referenced automatically when using Microsoft.NET.Sdk.WindowsDesktop - you don't have to do anything. This includes UIAutomation.dll.

One caveat - there is currently a bug in .NET Core 3.0 that excludes theme assemblies from being referenced automatically - see dotnet/wpf#765. We plan to fix it in .NET Core 3.1.

Thanks for the quick response. The only way I could make this work was copying the dll manually. I see this as a regression .

Would you explain your scenario better, possibly with a self-contained minimal repro project attached? I'm not quite following what you are trying to do that requires you to copy UIAutomationClient.dll manually, or browse to it and add a reference to it using the Visual Studio Reference Manager.

Given the fact that UIAutomationClient.dll is implicitly referenced by all Microsoft.NET.Sdk.WindowsDesktop projects when <UseWPF>true</UseWPF> is set in the project, such projects would get a reference to it automatically without needing any additional work. If you are having to do more here, I'd like to understand your scenario better.

What if you need to reference UIAutomation in a program which is not a Desktop app and does not use WPF? Is there a reliable way to ref it besides copying over dlls?

[vatsan-madhavan]

You can use a FrameworkReference to Microsoft.WindowsDesktop.App.Wpf from a console app and get references to WPF assemblies (which includes UIA* assemblies).

Hello
After adding a manual reference to C:\Program Files\dotnet\packs\Microsoft.WindowsDesktop.App.Ref\5.0.0\ref\net5.0\UIAutomationClient.dll into my .NET 5.0 WinForms project (as suggested by @vatsan-madhavan), it solved my compilation issue for System.Windows.Automation classes (thanks!)

However, I've got this warning below (but the project builds ok). Any idea how to fix that?
