Unlisted Dependency

[TonyValenti]

Hi ASPNet Team, I am trying to use the HttpSysServer in a project and I'm getting the error message below.

Itseems as though my project is missing a reference, but I'm noticing that System.Threading.Overlapped is not listed as a package dependency for this project. Are there any other unlisted dependencies I should add?

System.IO.FileNotFoundException: Could not load file or assembly 'System.Threading.Overlapped, Version=0.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

What package version is this?

Also, this is for .NET 4.x, not .NET Core 2.0, correct?

[TonyValenti]

I am using this DLL: C:\Users\Tony Valenti\source\repos\AlphaDrive\packages\Microsoft.AspNetCore.Server.HttpSys.2.0.3\lib\netstandard2.0\Microsoft.AspNetCore.Server.HttpSys.dll

and it has this version: 2.0.3.0

[Tratcher]

And you're running on .NET Core 2 or .NET 4.x?

[TonyValenti]

I'm not sure how to answer that question. The library is a cross platform library that I'm compiling for .NET 4.6.1.

Oddly, my app works fine on Windows 10, but on Windows 7 I get the error mentioned.

[TonyValenti]

Actually, I guess I see the error happening on windows 10 too. Apparently it is just not happening on my dev box.

This seems like an issue specific to your project dependency setup. Can you share a dummy project on github that reproduces it?
