C# – Is it possible to call a shared library (.so) on linux platform from .NET core

.net coreccross platformnetshared-libraries

I understand that aim of the .NET core is for cross platform development, but I am looking for backward compatibility. If I have a linux library available (maybe, legacy) and I want its functions to be called from .NET core application for linux platform. Is it possible?

I am not talking about ASP.NET core, I need it for a desktop application.

Yes: https://github.com/dotnet/corefx/issues/343

That being said, I'll admit to not having actually tried it yet. I have used this a far bit on Mono, for what it's worth, and it's definitely worth reading their documentation on this: http://www.mono-project.com/docs/advanced/pinvoke/ ... because .net core seems to take much the same approach (eg: leave off the file extension for the p-invoked library, so the system can take care of linking to the right version etc...)

Eg how bits of .net core itself do this:

const string LIBC = "libc";

[DllImport(LIBC, EntryPoint = "getenv")]
private static extern IntPtr getenv_core(string name);

C# – Reading settings from app.config or web.config in .NET

For a sample app.config file like below:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="countoffiles" value="7" />
    <add key="logfilelocation" value="abc.txt" />
  </appSettings>
</configuration>

You read the above application settings using the code shown below:

using System.Configuration;

You may also need to also add a reference to System.Configuration in your project if there isn't one already. You can then access the values like so:

string configvalue1 = ConfigurationManager.AppSettings["countoffiles"];
string configvalue2 = ConfigurationManager.AppSettings["logfilelocation"];
