Trailhead seems to not be working well today.  It isn't recording my completed challenges and now is saying that I need to log in, but then won't let me do so.  Any idea?

Hi ,

I have one WSDL file Simply made by "Hello World " Example by default in MS Visual Studio, when i use this file to Generate from WSDL it will give error.
So wht i should keep in mind while creating the WSDL for using in to the salesforce ?

is there any specific way for this ?
