Same issue here when trying to call this line of code:

this.tm.LanguageDirection.AddTranslationUnit(tu, new ImportSettings());

where tu is a translation unit with target language set as var tu = new TranslationUnit(sourceSegment, new Segment(new CultureInfo("zh-CN")));

I am also on Trados Studio 2022, version 17.0.6.14902

I have also included this on my App.config file, but it does not have any effect:

<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
        <dependentAssembly>
            <assemblyIdentity name="icu.net" publicKeyToken="416fdd914afa6b66" culture="neutral" />
            <bindingRedirect oldVersion="0.0.0.0-2.7.0.0" newVersion="2.7.0.0" />
        </dependentAssembly>
    </assemblyBinding>

Please can you check this out?

Hi Bram van der Steen   Stelios Mathioulakis , thx for reporting this issue; I'll followup today and circle back to you

Hi Bram van der Steen , Stelios Mathioulakis , It appears that we'll need to add another binding redirect to resolve dependency changes against the latest releases.

Please add both of these binding redirects to your app.config file and let me know if it resolves the issue.

<dependentAssembly>
  <assemblyIdentity name="icu.net" publicKeyToken="416fdd914afa6b66" culture="neutral" />
  <bindingRedirect oldVersion="0.0.0.0-2.7.0.0" newVersion="2.7.0.0" />
</dependentAssembly>

<dependentAssembly>
	<assemblyIdentity name="Microsoft.Extensions.DependencyModel" publicKeyToken="adb9793829ddae60" culture="neutral" />
	<bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0" />
</dependentAssembly>

It works now, thanks

Yes, perfect. Thank you very much!
