IPipelineBehavior doesn't work with IRequest

[GeorgeKarlinzer]

IPipelineBehavior cannot be used with IRequest (not IRequest<out TResponse>), because IPipelineBehavior requires TResponce as well as TRequest, but IRequest does not have a return value. Is it possible to add a pipeline behavior for IRequest?

MediatR/src/MediatR/IPipelineBehavior.cs

Lines 20 to 30 in c295291

	public interface IPipelineBehavior<in TRequest, TResponse> where TRequest : notnull
	{
	/// <summary>
	/// Pipeline handler. Perform any additional behavior and await the <paramref name="next"/> delegate as necessary
	/// </summary>
	/// <param name="request">Incoming request</param>
	/// <param name="next">Awaitable delegate for the next action in the pipeline. Eventually this delegate represents the handler.</param>
	/// <param name="cancellationToken">Cancellation token</param>
	/// <returns>Awaitable task returning the <typeparamref name="TResponse"/></returns>
	Task<TResponse> Handle(TRequest request, RequestHandlerDelegate<TResponse> next, CancellationToken cancellationToken);
	}

MediatR/src/MediatR.Contracts/IRequest.cs

Lines 6 to 17 in c295291

	public interface IRequest : IBaseRequest { }
	/// <summary>
	/// Marker interface to represent a request with a response
	/// </summary>
	/// <typeparam name="TResponse">Response type</typeparam>
	public interface IRequest<out TResponse> : IBaseRequest { }
	/// <summary>
	/// Allows for generic type constraints of objects implementing IRequest or IRequest{TResponse}
	/// </summary>
	public interface IBaseRequest { }

Pipeline behaviors DO work with void requests, and my unit tests show it. I suspect you may not have adjusted your generic constraints on one of the recent releases, you may want to re-check that.

You are right, I triple checked my code and it was my problem, thank you
