Hello, I have template project that use parameters of the type $Namespace$, for example.

Here you have the reference to the VS Template parameters: http://msdn2.microsoft.com/en-us/library/eehb4faa(VS.80).aspx

Hi, there are two kinds of templates: The VS Template and the T4 templates. You can pass paremeters to both of them. What are your trying to do? Passing parameters to a VS template when you are unfolding a template? or passing parameters to a T4 when you are unfolding a T4 template executing the UnfoldTemplateAction?

If your are in the second scenario you can pass parameters to the template as action inputs. For example:

<Action Name="GenerateProvider"
Type="TextTemplateAction"
Template="Provider.t4">
<Input Name="ProviderName" RecipeArgument="ProviderName" />
<Output Name="Content" />
</Action>

I'm sure if I'm following you. If you are using a VS template you shouldn't need an action for unfolding it. The template should be registered when the Guidance Package is registered and you should be able to create the template via the Menus "New Project", "New Item". Anyway if you are using VS Templates you should be able to replace the parameters if the recipe contains arguments with the same name.

For example: If you have an argument called "Namespace" of type string in your recipe, then you should be able to use it in your VS Template as $Namespace$.

Are you executing a recipe as part of the template unfolding?

I am not exposing template directly.

I am calling to template from recipe.

The recipe realiza ejecuta varias acciones previamente, como ser crear carpetas en la solucion, y luego carga en estas los template de proyecto.

Es por esto, que el template es llamado desde un recipe por medio del UnfoldTemplateAction.

I am using the following action inside the recipe:

<Action Name="UnfoldWCFBusinessEntityProjectTemplate" Type="UnfoldTemplateAction" Path="">

<Input Name="ItemName" ActionOutput="GetWCFProjectsName.BusinessEntityProjectName" />

<Input Name="Root" ActionOutput="CreateBusinessLogicFolder.NewFolder" />

<Input Name="Template" ActionOutput="GetWCFTemplatePathBusinessEntity.TemplateFilePath" />

<Input Name="DestinationFolder" ActionOutput="CreateFolderStructureBusinessEntity.FullPath" />

<Output Name="NewItem" />

</Action>

This is the alias of the action:

<TypeAlias Name="UnfoldTemplateAction" Type="Microsoft.Practices.RecipeFramework.Extensions.Actions.Templates.UnfoldTemplateAction, Microsoft.Practices.RecipeFramework.Extensions" />

But this not suport parameters.

Thanks

Could you post the template code please?

btw: are you defining the path attribute in the action "UnfoldWCFBusinessEntityProjectTemplate"?

Thanks,

Exactly, in input to parameter “Template� I specify the complete physical route where is .vstemplate, for that reason is another action the one in charge to solve it.

Recipe is a little great, I am going to see shorten it a little to send it in the message.

<Argument Name="ProjectName">

<ValueProvider Type="Evaluator" Expression="ProjectExample" />

</Argument>

But it does not take the value from the argument like parameter of template.

In this case simply I am using a fixed value in the parameter, “ProjectExample� to notice that it is replaced.

The thing is that the UnfoldTemplateAction is for unfolding *T4* templates. You are trying to unfold a .vstemplate using this action. The syntax $ProjectName$ won't work. Instead you should be using the T4 syntax (<#= ProjectName #>).

Take a look at the T4 section in the Guidance Automation Toolkit documentation for an overview of the T4 syntax.
