Request: support @model directive

[sergeyt]

I've noticed it is not supported yet, right?

[adoconnection]

@model is controlled by RazorEngineCore itself so you dont need to use this directive and need to remove it from your template.

@using is supported too. Most likely you will need to explicitly link assembly https://github.com/adoconnection/RazorEngineCore/wiki/@Inject-and-referencing-other-assemblies#linking-assemblies
(I was unable to parse @using-s and do it programatically in a reasonable time)

[adoconnection]

To keep intellisense suggestions use @Inherits instead of @model

[sergeyt]

@adoconnection thanks for clarifications. Checked that @using works.

Note @inherites cannot be used for classes without parameterless constructor. So @model would be nice to support (e.g. just ignore it on compile time).

[adoconnection]

@sergeyt wont it be hidden surprice, if someone will put @model TypeA directive and then figure out it was ignored and replaced by RazorEngineCode?

[sergeyt]

@adoconnection it can be a documented limitation/behavior. @model is for VS intellisense wheen @inherits is not applicable

[garryxiao]

@adoconnection, parse the usings is little bit reasonable. Is it possible for me to do some work here? :)
@sergeyt, I mention something under #50 may help.

[adoconnection]

@garryxiao sure, the only thing is I would like it to be done using Razor tools, sinse razor somehow parse them there should be a way to get usings collection. But I was not able to find out how.

There is always a plan B to use regex or something on a template string, I would like to avoid that.

Please include this in the wiki, or make the wiki public so I could add it :)

[adoconnection]

@304NotModified wiki is open now :)

[304NotModified]

Done! https://github.com/adoconnection/RazorEngineCore/wiki/@model-and-Visual-Studio-IntelliSense

Note @inherites cannot be used for classes without parameterless constructor.

Is this really true? I tried it and don't see the issue? (check IntelliSense, compiling and running?)

it can be a documented limitation/behavior. @model is for VS

I really prefer support for parsing @model and documenting this behavior. Maybe also with a better error message? If we use now @model MyModel, we get this error:

RazorEngineCore.RazorEngineCompilationException
Unable to compile template: j2rpxc2v.45u(7,7): error CS0103: The name 'model' does not exist in the current context
   at RazorEngineCore.RazorEngine.CreateAndCompileToStream(String templateSource, RazorEngineCompilationOptions options)
   at RazorEngineCore.RazorEngine.Compile[T](String content, Action`1 builderAction)

Any leads where to start to get this implemented?

I'm having an issue where I'm trying to use the example for @include and Template, combined with the example for strongly-typed models using @inherit Base.

The problem is that the templating approach shows you should use a MyTemplateBase, but that's not generic, so I can't put @include MyTemplateBase<MyModel> at the top as it doesn't accept T. I tried making it generic, but got stuck here:

[benmccallum]

It seems like maybe this wrapper is only required when the model is an anonymous type, based on here:

RazorEngineCore/RazorEngineCore/RazorEngineCompiledTemplate.cs

Lines 94 to 97 in a86a24b

	if (model != null && model.IsAnonymous())
	{
	model = new AnonymousTypeWrapper(model);
	}

So in my case I can probably just remove that code. Will see how I go
