On every generated model classes there are no documentation comments added by default. If you want to use XML documentation comments for every generated entity classes, find this part inside [modelname].tt (modelname is current EDMX file name):
foreach (var entity in typeMapper.GetItemsToGenerate<EntityType>(itemCollection))
{
fileManager.StartNewFile(entity.Name + ".cs");
BeginNamespace(code); // used to write model namespace
#>
<#=codeStringGenerator.UsingDirectives(inHeader: false)#>
You can add the XML documentation comments before UsingDirectives
line as shown in example below:
foreach (var entity in typeMapper.GetItemsToGenerate<EntityType>(itemCollection))
{
fileManager.StartNewFile(entity.Name + ".cs");
BeginNamespace(code);
#>
/// <summary>
/// <#=entity.Name#> model entity class.
/// </summary>
<#=codeStringGenerator.UsingDirectives(inHeader: false)#>
The generated documentation comment should be includes entity name as given below.
/// <summary>
/// Example model entity class.
/// </summary>
public partial class Example
{
// model contents
}
