[.NET] I don't have time for this. POCO Generator, Function Imports, Returning None

1. Used POCO Generator to create Function Imports
2. Had a Function that returns none
3. POCO Generator does not generate Functions that return none.

Alright, this was such a headache, but thanks to Matt Johnson in this stack overflow link:
http://stackoverflow.com/questions/3797248/update-function-import-not-displaying-in-context-file

...problem was solved.

Here is the Function Import region of the .tt file:


region.Begin("Function Imports");

        foreach (EdmFunction edmFunction in container.FunctionImports)
        {
            var parameters = FunctionImportParameter.Create(edmFunction.Parameters, code, ef);
            string paramList = String.Join(", ", parameters.Select(p => p.FunctionParameterType + " " + p.FunctionParameterName).ToArray());
            string returnTypeElement = edmFunction.ReturnParameter == null
? null : code.Escape(ef.GetElementType(edmFunction.ReturnParameter.TypeUsage));

#>
    <#=Accessibility.ForMethod(edmFunction)#> <#= returnTypeElement == null ? "int" : ("ObjectResult<" + returnTypeElement + ">") #>  <#=code.Escape(edmFunction)#>(<#=paramList#>)
    {
<#
            foreach (var parameter in parameters)
            {
                if (!parameter.NeedsLocalVariable)
                {
                    continue;
                }
#>

        ObjectParameter <#=parameter.LocalVariableName#>;

        if (<#=parameter.IsNullableOfT ? parameter.FunctionParameterName + ".HasValue" : parameter.FunctionParameterName + " != null"#>)
        {
            <#=parameter.LocalVariableName#> = new ObjectParameter("<#=parameter.EsqlParameterName#>", <#=parameter.FunctionParameterName#>);
        }
        else
        {
            <#=parameter.LocalVariableName#> = new ObjectParameter("<#=parameter.EsqlParameterName#>", typeof(<#=parameter.RawClrTypeName#>));
        }
<#
            }
#>
        return base.ExecuteFunction<#= returnTypeElement == null ? "" : ("<" + returnTypeElement + ">")#>("<#=edmFunction.Name#>"<#=code.StringBefore(", ", String.Join(", ", parameters.Select(p => p.ExecuteParameterName).ToArray()))#>);
    }
<#
        }

        region.End();
