Microsoft.AnalysisServices 19.86.2.1 is not adapted to work on Linux.

Question

Hi,

When I try to connect to Server from Microsoft.AnalysisServices.Tabular on my local machine which is on Windows, it works correctly. While in Kubernetes cluster I get the error

The type initializer for 'Microsoft.AnalysisServices.Hosting.ClientHostingManager' threw an exception. Value cannot be null. (Parameter 'path1')

my class stack trace

Inner exception System.ArgumentNullException handled at Microsoft.AnalysisServices.Hosting.ClientHostingManager.get_IsProcessWithUserInterface: at System.ArgumentNullException.Throw (System.Private.CoreLib, Version=8.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e) at System.IO.Path.Combine (System.Private.CoreLib, Version=8.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e) at Microsoft.AnalysisServices.Configuration.ClientConfigLoader.AddDefaultConfigurationValues (Microsoft.AnalysisServices.Runtime.Core, Version=19.86.2.1, Culture=neutral, PublicKeyToken=89845dcd8080cc91) at Microsoft.AnalysisServices.Configuration.ClientConfigLoader.LoadClientConfiguration (Microsoft.AnalysisServices.Runtime.Core, Version=19.86.2.1, Culture=neutral, PublicKeyToken=89845dcd8080cc91) at Microsoft.AnalysisServices.Hosting.ClientHostingManager.InitializeRuntimeAndClientConfiguration (Microsoft.AnalysisServices.Runtime.Core, Version=19.86.2.1, Culture=neutral, PublicKeyToken=89845dcd8080cc91) at Microsoft.AnalysisServices.Hosting.ClientHostingManager.InitializeConfiguration (Microsoft.AnalysisServices.Runtime.Core, Version=19.86.2.1, Culture=neutral, PublicKeyToken=89845dcd8080cc91) at Microsoft.AnalysisServices.Hosting.ClientHostingManager.Initialize (Microsoft.AnalysisServices.Runtime.Core, Version=19.86.2.1, Culture=neutral, PublicKeyToken=89845dcd8080cc91) at Microsoft.AnalysisServices.Hosting.ClientHostingManager..cctor (Microsoft.AnalysisServices.Runtime.Core, Version=19.86.2.1, Culture=neutral, PublicKeyToken=89845dcd8080cc91)

Digging deeper led me to ClientConfigLoader in Microsoft.AnalysisServices.Runtime.Core namespace. In AddDefaultConfigurationValues method it has this

  if (!config.ContainsKey(262145))    {        
config.Add(262145,Path.Combine(Path.GetPathRoot(Environment.SystemDirectory), "ASClientDiagnostics"));    
}

Environment.SystemDirectory for Windows is C:\WINNT\System32. But for Linux, it will be "". As a result Path.GetPathRoot(Environment.SystemDirectory) returns null and Path.Combine fails with null for path1.

How to workaround this (except running a windows pool in Kubernetes) or how to create bug report to the team owning it?

I don't know if MSFT saw this question or if it was an already known issue, but it was fixed in latest update. Thanks. Code in question was updated to this:

if (!config.ContainsKey(262145))
{
    string text = Environment.SystemDirectory;
    if (string.IsNullOrEmpty(text))
    {
        text = AppContext.BaseDirectory;
    }
    if (string.IsNullOrEmpty(text))
    {
        text = Assembly.GetEntryAssembly().Location;
    }
    if (string.IsNullOrEmpty(text))
    {
        text = Environment.CurrentDirectory;
    }
    config.Add(262145, Path.Combine(Path.GetPathRoot(text), "ASClientDiagnostics"));
}

So resolution - update Microsoft.AnalysisServices to version 19.86.6 (at least).
