Expected behavior

I tried to use the ParquetReader.OpenFromFile(filepath), i never manipulated .parquet files, and i was playing around, trying to understand better the benefits of using .parquet files on my .net core projects.

Actual behavior

When calling the line: ParquetReader.OpenFromFile(filepath);

Unhandled exception. System.IO.FileLoadException: Could not load file or assembly 'Parquet, Version=3.0.0.0, Culture=neutral, PublicKeyToken=d380b3dee6d01926'. The located assembly's manifest definition does not match the assembly reference. (0x80131040) File name: 'Parquet, Version=3.0.0.0, Culture=neutral, PublicKeyToken=d380b3dee6d01926' at parquet.Program.Main(String[] args)

Steps to reproduce the behavior

Simply add parquet-dotnet package to the project

Code snippet reproducing the behavior

using System;
using System.Collections.Generic;
using Newtonsoft.Json;
using Parquet;

namespace parquet
{
    class Program
    {
        static void Main(string[] args)
        {
            // Console.WriteLine(tat2.RowGroupCount);

            Console.WriteLine("OI");
            JsonConvert.SerializeObject("ahhh");
            var tat2 =   ParquetReader.OpenFromFile("userdata1.parquet");

        }
    }
}

I´m using VS Code with OmniSharp, idk if i´m doing something wrong.

It's due to your namespace/project being named parquet. So when it builds it will create a mismatch Parquet.dll and your project's output dll(also parquet.dll). Try renaming the project to something else and it should work.
