Visual Studio 2015 Scaffolding is not working

Question

Hi everybody,

In our project we're using scaffolding to create necessary files. It works fine in VS 2013. I got a new laptop with VS 2015 installed and the scaffolding is no longer working. It doesn't work for other developers in the team in VS 2015.

I'm getting the following error when I try to activate the Package Manager Console and try to run the scaffolding command:

I tried re-installing t4scaffolding and t4Core and got some errors along the way as well. What is the solution for this problem?

Hi Naomi  N,

It seems that other members also meet the simliar issue like this issue:

http://stackoverflow.com/questions/31890649/t4-scaffolding-not-working-with-visual-studio-2015

Like David Anderson's suggestion, since it worked well in VS2013, but not in VS2015, if possible, please make sure that it is not the extension tool issue. For example, maybe it has a new update version like the NuGet package update or others.

Best Regards,

Jack

Yes, thanks. I saw that discussion and will be waiting for instructions. For now I'm working on my older laptop with VS 2013 installed.

Strange, but the link doesn't work for me anymore. Can anyone still access it? Why would it disappear?

David Anderson released a new version of the MVC Scaffolding that resolved the problem for me in VS 2015.

Answer 11

UPDATE. After I uninstalled everything related to VS 2015 for scaffolding, I was able to Scaffold from Visual Studio 2015.

In Visual Studio 2017 I got no output and nothing got generated (silently).

------------------------------------------------------------------------------

Ok, I'm back to exactly same problem again but now I have VS 2017 and VS 2015.

In VS 2015 I'm getting

 

PM> Scaffold SysManager.ScaffoldBackend.For IItem
Invoke-Scaffolder : A positional parameter cannot be found that accepts argument 'IItem'.
At line:1 char:1
+ Scaffold SysManager.ScaffoldBackend.For IItem
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidArgument: (:) [Invoke-Scaffolder], ParameterBindingException
    + FullyQualifiedErrorId : PositionalParameterNotFound,T4Scaffolding.Cmdlets.InvokeScaffolderCmdlet

In VS 2017 it just silently does absolutely nothing. I uninstalled MVC and T4 Scaffoldings for 2015 and only left 2017 scaffolding installed (the very latest released today).

Still it doesn't work for me.

Please help.
