Microsoft.Bcl.AsyncInterfaces dependency issue

[mtissington]

Describe the bug Using CsvHelper 32.0.3 Visual Studio 2022 Professional (latest updates) 17.10.1 Built project with .NET 4.8. When attempt to use csv I get an error that Microsoft.Bcl.AsyncInterfaces or one of it's dependencies is missing. I've installed (not installed automatically) Microsoft.Bcl.AsyncInterfaces Microsoft.Bcl.HashCode

To Reproduce Build .NET 4.8 project

Expected behavior CSV should run without error and find Microsoft.Bcl.AsyncInterfaces

Is this related to #2230 ?

I have same issue. ASP.NET 4.8 already target to Microsoft.Bcl.AsyncInterfaces 8.0.0, but CsvHelper throw error vserion 7.0.0 not found (System.IO.FileLoadException)

I noticed that the issue only happened in our shipping product. The internal debug and release builds worked. Turns out we were not packaging the app.config file - once we did that it worked.

This is the contents of the config file

@mtissington thanks, it helped me! ASP.NET Web.config was missing an entry:

<dependentAssembly>
    <assemblyIdentity name="Microsoft.Bcl.AsyncInterfaces" publicKeyToken="cc7b13ffcd2ddd51" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-8.0.0.0" newVersion="8.0.0.0" />
</dependentAssembly>
