disable default validation in Asp.Net WebAPI

Question

I want to completely disable model validation for WebAPI controllers. I tried a few ways to do it for MVC, but seems WebAPI doesn't get that methods.

In my case:

I'm trying to completely remove step 2.

can u clarify further. do you have data annotations setup on your poco classes? do you have code in http verb methods that look like if(ModelState.IsValid)? if so you should remove that. Maybe I'm not fully understanding you. — origin1tech

I`m trying to completely remove default validation, not just ignore it. — Oleh Nechytailo

Not enough upvotes on this question ;-) This validation, we didn't know or care about, was automatically running every method in every object we sent, killing performance by about 3000% (confirmed via profiling). Very relieved to turn it off. — PandaWood

Try this:

config.Services.Clear(typeof(ModelValidatorProvider));

It should completely disable validation both for URI parameters and for body parameters.

It throws exception "ModelValidatorProvider is not supported", so I removed System.Web.Http.Validation.IBodyModelValidator and it works! Thanks.

On thing to note, this needs to be called before EnsureInitialized() or the route bindings will be setup with the default validator.

One more thing. It is the System.Web.Http.Validation.ModelValidatorProvider
