Max upload size for ASP.MVC CORE website

Question

How can I set maximum upload size for an ASP.NET CORE application?

In the past I was able to set it in web.config file like this:

<system.webServer>
    <security>
        <requestFiltering>
            <requestLimits maxAllowedContentLength="52428800" />
        </requestFiltering>
    </security>
</system.webServer>

Answer 1

Two ways to do that:

1.Using application wise settings - in the > configure services method.

services.Configure<FormOptions>(options =>
{
    options.MultipartBodyLengthLimit = 52428800;
});

2.Using RequestFormSizeLimit attribute - for specific actions. - It is not yet available in official package Unofficial

Answer 2

You can configure the max limit for multipart uploads in the ConfigureServices method:

public void ConfigureServices(IServiceCollection services)
{
    services.Configure<FormOptions>(options =>
    {
        options.MultipartBodyLengthLimit = 52428800;

    });

    services.AddMvc();
}

You can also configure the MaxRequestBufferSize by using services.Configure<KestrelServerOptions>, but it looks like this is going to be deprecated in the next release.
