Could not load file or assembly Microsoft.Identity.Client, Version=4.22.0.0

Comienza reproduciendo la prueba que falla alrededor de SqlAgentService.ExecuteJob e inspecciona el app.config y las referencias de paquetes del proyecto de pruebas independiente de .NET 4.8. Compara las versiones de Microsoft.Identity.Client resueltas por el proyecto de pruebas y por Microsoft.SqlServer.SqlManagementObjects y, a continuación, verifica que la prueba ya no genere el error de carga del ensamblado.

I have a .NET 4.8 framework Windows application that is using Microsoft.SqlServer.SqlManagementObjects (v161.47027.0) in its own class. I am unit testing that class in a separate .NET 4.8 library test project.

However when I run a test like so:

[Test]
public void SqlAgentJobDoesntExist_ThrowsException()
{
     var connection = new SqlConnectionStringBuilder(ConnectionString); //ConnectionString coming from app.config in the test project
     var sqlAgent = new SqlAgentService(connection);
     Assert.Throws<NullReferenceException>(() => { var result = sqlAgent.ExecuteJob("NotFound"); });
}

It is throwing an error around this bit of code in my service class:

public CompletionResult ExecuteJob(string jobName)
{
    try
    {
        var connection = new ServerConnection(_connectionBuilder.DataSource, _connectionBuilder.UserID, _connectionBuilder.Password);
        var server = new Server(connection);
        var job = server.JobServer.Jobs[jobName]; //<-- throwing error here
...

Error:

Microsoft.SqlServer.Management.Common.ConnectionFailureException : Failed to connect to server XXXXXXXXXXX.
----> System.TypeInitializationException : The type initializer for 'Microsoft.Data.SqlClient.SqlAuthenticationProviderManager' threw an exception.
----> System.IO.FileLoadException : Could not load file or assembly 'Microsoft.Identity.Client, Version=4.22.0.0, Culture=neutral, PublicKeyToken=0a613f4dd989e8ae' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Two reasons this is odd:

1. The application itself is working fine (the main project), this error is only happening in my unit test project
2. It's odd because SMO already installs Microsoft.Identity.Client as a dependency when adding as a NuGet package. Why is it asking for this older 4.22 version?
