There should be two new project templates available to you.

'Basic' and 'Entity'

Provided C# templates (sagecrm.com)

The Entity Template should prompt you for the name of the entity, its prefix and primary key name.  The classes that it creates gives examples of how to code the different pages to support a custom entity.  It assumes that you have created the entity using the Advanced Customization Wizard (with the .NET flag set).

Ok, getting somewhere now. Found some very old examples of your code which have a little of what I need. Even though the stuff is deprecated, I work out the newer code. I'll report back when I get further.

Hi Vega

I've been on holiday so excuse the late response.

The SDK contains several project that demonstrate how to use the API in anger.

These mostly use the Basic Template as that assumes the developer wants to do most of the work.  The Entity Template will generate a set of specialised classes that show how they work.

I've written quite a bit about using the specialised classes

Hi Jeff.

Thanks. My assumption is that when I create a new entity, I use the entity wizard as normal, and when I create the new entity, I tick the box for dot net and it creates the metadata entries I need for it. I then load VS and choose the entity template and follow the wizard and generate the skeleton structure for the project. I'm making progress on it. To clarify, the basic template is used for standard screens and extensions, and the entity template is used when you have created a ne.

Generally yes.
