[VCPKG] Visual Studio Preview 5 v17.12 caused SDK Resolver Failure on Microsoft.Build.Vcpkg

[RobsonPontin]

Describe the bug

Updating from Visual Studio Preview 3 to Preview 5 caused the VCPKG targets to no longer load C++ projects due to the following error:

D:\repos\MyRepo\src\MyLib\MyLib.vcxproj : error  : SDK Resolver Failure: "The SDK resolver "Microsoft.DotNet.MSBuildSdkResolver" failed while attempting to resolve the SDK "Microsoft.Build.Vcpkg". Exception: "System.IO.FileNotFoundException: Could not load file or assembly 'System.Text.Json, Version=8.0.0.4, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The system cannot find the file specified.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].
""  D:\repos\MyRepo\Directory.Build.targets

The issues is related to the file Directory.Build.Targets which has the SDK entry for Microsoft.Build.Vcpkg:

<?xml version="1.0" encoding="utf-8"?>
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <Sdk Name="Microsoft.Build.Vcpkg" />
</Project>

This works fine with latest VS 2022 17.11.5 and I did test it with VS 2022 Preview 3.

Also note that the project I'm working on is a WinUI 3 apps.

To Reproduce

Having C++ projects on a WinUI 3 solution, add Directory.Build.Targets file with the SDK entry for Microsoft.Build.Vcpkg.

<?xml version="1.0" encoding="utf-8"?>
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <Sdk Name="Microsoft.Build.Vcpkg" />
</Project>

Exceptions (if any)

error  : SDK Resolver Failure: "The SDK resolver "Microsoft.DotNet.MSBuildSdkResolver" failed while attempting to resolve the SDK "Microsoft.Build.Vcpkg". Exception: "System.IO.FileNotFoundException: Could not load file or assembly 'System.Text.Json, Version=8.0.0.4, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The system cannot find the file specified.

I have the same error with you. But the scenery is a little different. First, create a CLR project A. Then add a C# project. Close VS and open the sln again. The project A shows unloaded. The error in output windows shows:

G:\Sync\C++\ClassLibrary1\ClassLibrary1\ClassLibrary1.vcxproj : error  : SDK Resolver Failure: "The SDK resolver "Microsoft.DotNet.MSBuildSdkResolver" failed while attempting to resolve the SDK "Microsoft.NET.Sdk". Exception: "System.IO.FileNotFoundException: Could not load file or assembly 'System.Text.Json, Version=8.0.0.4, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The system cannot find the file specified.

I believe this should be fixed in 17.12.0 which released today. Please try that and report back if it's not resolved.

Just tried VS v17.12 and no longer see the issue.
all good, thank you.
