Allow Null params to middleware constructor? #331
Description
I want to do this from Startup.cs:
app.UseMiddleware<MyMiddleware>( foo );
MyMiddleware looks like this:
public class MyMiddleware
{
private readonly RequestDelegate m_next;
public MyMiddleware( RequestDelegate next, Foo foo )
{
m_next = next;
// use foo
}
public async Task Invoke( HttpContext httpContext )
{
await m_next( httpContext );
}
}
Yet I keep getting:
System.InvalidOperationException
Unable to locate suitable constructor for type 'MyMiddleware'. Ensure the type is concrete and all parameters are accepted by a constructor.
How do I pass additional parameters in my middleware constructor?
