Custom ASP.NET Core Formatters to support reading and writing Protocol Buffers from / to a HTTP request / response.

Install-Package AspCoreProtobufFormatters -Version 1.0.0

Inside your normal Startup.cs file add the following at the top of the file:

using AspCoreProtobufFormatters.Extensions;

Then you can call .AddProtobufFormatters() on a MvcOptions.

Usually it would look something like this:

public void ConfigureServices(IServiceCollection services)
{
    services.AddControllers(options => 
    {
        options.AddProtobufFormatters()
    });
}

Or:

public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc(options => 
    {
        options.AddProtobufFormatters()
    });
}

For more info on configuring services see App startup in ASP.NET Core.

From there you can use protobufs as an argument to your end point methods. Note: by default, the client must set the content type as 'application/x-protobuf' in order for these formatters to be used.
