[Bug]: Animate requires IVersionProvider registered after update from 2.1.3 to 2.2.x

[manuelelucchi]

Blazorise Version

2.2.X

What Blazorise provider are you running on?

None

Link to minimal reproduction or a simple code snippet

I don't have time to create a repro, I always used Animate tags without registering anything.

Steps to reproduce & bug description

Use the Animate tags in a new empty Blazor project

What is expected?

To not requiring another service to work or at least the docs to report what should I register

What is actually happening?

Same as described before

What browsers do you see the problem on?

No response

Any additional comments?

No response

[stsrki]

Can you please give more details? Do you get any errors with Animate?

[manuelelucchi]

I get a simple DI exception from blazor

Can you confirm you have

services
            .AddBlazorise( options =>
            {
                // ...
            } )

in your startup?

In case you have Blazor Auto-rendering, you should have to have two AddBlazorise. One for the server project and one for the client project.

[manuelelucchi]

With AddBlazorise (on both projects, nothing configured explicitly) the exception changes slightly

blazorise.animate.js?v=1.7.6.0:5 [Blazorise.Animate] blazorise.animate.js is obsolete. The Animate component now imports _content/Blazorise.Animate/animate.js as a JavaScript module.

[stsrki]

You might be using an older NuGet package somewhere. Check your dependencies and make sure all are using Blazorise 2.2.1.

[manuelelucchi]

I have no other Blazorise packages and it's installed only on a shared assembly between client, server and a maui app

[stsrki]

Ah. I believe you only need to remove blazorise.animate.js from your index/host file. We made it so that it is not needed anymore. Js files are now handled automatically as modules.
