Template Wizards, IWizard Interface - GetService?

Jaeden Ruiner 126

Okay,

I'm a little frustrated. Migrated to many versions of the TemplateWizardInterface which broke my stuff. Now, I wanted to be on the latest versions of everything but that broke VS2019, and I need to maintain both 2019 and evolve to 2022, but that is at a later date.

Currently I've completely reverted to following NuGet packages:

EnvDTE (8.0.1)
EnvDTE80 (8.0.1)
VSSDK.TemplateWizardInterface (12.0.4)
Nuget.VisualStudio (5.11.3)

This now works just fine as it always has.

However, in the IWizard interface there are a series of methods. The primary one being RunStarted() which passes in an "automationObject". This is just a type Object which must be cast to something.

Now, as you can see I am also referencing the Nuget.VisualStudio package, which has certain interfaces.

Most references I find on the Internet reference calling:

IVsPackageInstaller installer = GetService<IVsPackageInstaller>();

However, there is no method "GetService". That's on an IServiceProvider, or the IComponentModel for the modern libraries, which I do not have access to.

So, from the IWizard interface, how do I access a IServiceProvider or other such means in order to get a reference to the Nuget.VisualStudio objects?

Thanks

Is that a System.IServiceProvider, or is it in another namespace?

I'm just saying because i have seen a lot with not actual answers. give me nuget packages and actual code, not solutions that involve 3rd party answers that i have to figure out what is meant.

In the context of an IWizard interface, you can access an IServiceProvider in order to get a reference to the Nuget.VisualStudio objects using the following steps:

In the IWizard.RunStarted method, you can access the IServiceProvider by calling the GetService method of the DTE2 object passed to the method.
Copy code
    public void RunStarted(object automationObject, Dictionary<string, string> replacementsDictionary, WizardRunKind runKind, object[] customParams)
    {
        _dte = (DTE2)automationObject;
        _serviceProvider = (IServiceProvider)_dte;
    }
Once you have the IServiceProvider, you can use it to get a reference to the Nuget.VisualStudio objects you need. For example, to get a reference to the INuGetPackageManager object, you can use the following code:
Copy code
    var nugetPackageManager = (INuGetPackageManager)_serviceProvider.GetService(typeof(INuGetPackageManager));
Similarly, you can get the reference to other Nuget.VisualStudio objects like IVsPackageInstaller, IVsPackageInstallerServices, IVsPackageInstallerEvents, etc by calling the GetService method with the appropriate type.
It's important to note that the IServiceProvider is the way to get access to the Visual Studio services in your extension, and the Nuget.VisualStudio objects are part of the Visual Studio services so it's a way to access them.

This is Incorrect.
I have tried to cast the automationObject to a System.IServiceProvider and that throws an error.

Invalid Cast.
The "automationObject" parameter is of a type that does not implement IServiceProvider.
