hi @hikalkan
The current situation is that we can't get IConfiguration under the module's ConfigureServices method.

Currently using the following method to get IConfiguration, but this will be out of date.

var configuration = context.Services.BuildConfiguration();

Although can inject IConfiguration in the Startup class, this can't be integrated with abp.

Can you try this in ConfigureServices: context.Services.GetSingletonInstance<IConfiguration>()

[maliming]

Actually I tried. I can't get IConfiguration or IConfigurationRoot like IWebHostEnvironment.

Could not find singleton service: Microsoft.Extensions.Configuration.IConfiguration, Microsoft.Extensions.Configuration.Abstractions, Version=3.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60

Could not find singleton service: Microsoft.Extensions.Configuration.IConfigurationRoot, Microsoft.Extensions.Configuration.Abstractions, Version=3.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60

OK, let me check this.

[hikalkan]

var config = context.Services.GetSingletonInstanceOrNull<HostBuilderContext>().Configuration

should work. I changed services.GetConfiguration() to use the code above (see 0f24054), so you can use context.Services.GetConfiguration() just like before in ConfigureServices method.

Merge dev to your branch to be able to use it.

All done.
