What is default maximum request length in .net core

Question

I want to know what is default maximum request length in a .net core application.

I read from few links that the default limit is 4 MB for asp.net applications and same should apply here.

But on testing i found that even without overriding the default limit i am able to upload files of size around 14 MB but it fails for files of size around 30 MB.

I certainly know how to increase this limit but i want to know what is the default limit. Is there any c# code to check? Could not find any related documentation regarding this.

Answer 1

As of ASP.NET Core 6, the default maximum request body size is 30,000,000 bytes, which is approximately 28.6 MB. These are the same defaults if you are running against IIS or Kestrel.

The default maximum filesize is 4MB.

If you want to increase the upload size, you can do it like this:

Using application wise settings - in the configure services method. In this example, upload up to 100 MB file.

services.Configure<FormOptions>(options =>
{
    options.MultipartBodyLengthLimit = 100000000;
});
