C# Class SharpMap.Layers.WmsLayer

Web Map Service layer

The WmsLayer is currently very basic and doesn't support automatic fetching of the WMS Service Description. Instead you would have to add the nessesary parameters to the URL, and the WmsLayer will set the remaining BoundingBox property and proper requests that changes between the requests. See the example below.
