VSX:ProjectFlavor-only项VSTemplates?

在VisualStudio2005、2008和2010中,是否可以为特定ProjectFlavor的项目定义仅出现在“添加项”对话框中的项模板?如果我能帮忙的话,我宁愿不要把所有其他无关项目的additems对话框弄得乱七八糟。

<ProjectType>CSharp</ProjectType> 是一个固定枚举,我找不到ProjectFlavor guid或其他位置。

<TemplateData>
    <Name>MyProject A File</Name>
    <Description>MyProject A File to do stuff</Description>
    <Icon>A.ico</Icon>
    <TemplateID>TemplateID_A</TemplateID>
    <TemplateGroupID>MyTemplateGroupID</TemplateGroupID>
    <ProjectType>CSharp</ProjectType>
    <RequiredFrameworkVersion>2.0</RequiredFrameworkVersion>
    <SortOrder>20</SortOrder>
    <NumberOfParentCategoriesToRollUp>1</NumberOfParentCategoriesToRollUp>
    <DefaultName>Template_A.cs</DefaultName>
    <ProvideDefaultName>true</ProvideDefaultName>
    <ShowByDefault>false</ShowByDefault>
</TemplateData>
<TemplateContent>
    <ProjectItem ReplaceParameters="true">Template_A.cs</ProjectItem>
</TemplateContent>

在package.cs上:

// [ProvideProjectItem(typeof(MyProjectFactory), "MyTemplateGroupID", 
//    @"Templates\ProjectItems", 600)] // Took this out.

[ProvideProjectFactory(typeof(MyProjectFactory), 
    "My Project", "My Project Files (*.csproj);*.csproj", 
    null, null, @"Templates\Projects", 
    LanguageVsTemplate = "CSharp", 
    NewProjectRequireNewFolderVsTemplate = true, 
    TemplateGroupIDsVsTemplate="MyTemplateGroupID",
    TemplateIDsVsTemplate = "TemplateID_A,TemplateID_B")]
public sealed class MyPackage : Package { ... }
