## Resources in extensions

Resource files can now be packaged as part of an extension. To add resources to your extension, the following property has to be set in your app.json:

```JSON
"resourceFolders": [<list of folders that contain resources>]
```

The folders should be listed relative to the root of your project. For example:

```JSON
"resourceFolders": ["Resources"]
```

This will include all files under the folder 'resources'. The resource folders themselves can contain additional subfolders. For example, you could have the following folder structure:

```
MyApp
| - Resources/
  | - Images/
    | - MyImage.png
  | - Configuration/
    | - MyConfiguration.json
| - src/
  | - MyCodeunit.codeunit.al
```

Access to these resources is done through the `NavApp.GetResource("resource name": Text; var instream: Instream; [optional] encoding: TextEncoding)` method. The name of a resource is its path from the root of its resource folder. So for the folder structure above, you can do:

```AL
procedure MyProc()
var
    resultStream: Instream;
    jsonText: Text;
begin
    NavApp.GetResource("Images/MyImage.png", resultStream);
    // Do stuff with the blob in the resultStream object

    NavApp.GetResource("Configuration/MyConfiguration.json", resultStream, TextEncoding::UTF8);
    jsonText := resultStream.Read(jsonText);
end
```

There are also the methods `NavApp.GetResourceAsText("resource name": Text; [optional] encoding: TextEncoding): Text` and `NavApp.GetResourceAsJson("resource name": Text; [optional] encoding: TextEncoding): JsonObject` that directly retrieves resources as `Text` or `JsonObject` types.

The method `NavApp.ListResources([optional] filter: Text)` is also provided to allow for iteration over resources. The `filter` value for the method can contain wildcards. If it does not contain wildcards, then any resources with the filter text within its name will be returned. For example:

```AL
/**
* For the following resource structure:
* Resources/
*     Images/
*         SampleImage1.png
*         SampleImage2.png
*         SampleImage3.jpg
*         TemplateImage.jpg
*     Snippet/
*         SampleSnippet.txt
*         TemplateSnippet.txt
*/

// This will return: ["Images/SampleImage1.png","Images/SampleImage2.png","Images/SampleImage3.jpg", "SampleSnippet.txt"]
NavApp.ListResources("Sample");

// This will return: ["Images/SampleImage1.png","Images/SampleImage2.png"]
NavApp.ListResources("Images/*.png")
```

Resources can only be accessed within the scope of the app that contains them. This means that there is no way to access the resources of another app.

## AppSourceCop

- Addressed issues executing page breaking change validation rules [AS0029](https://learn.microsoft.com/dynamics365/business-central/dev-itpro/developer/analyzers/appsourcecop-as0029), [AS0035](https://learn.microsoft.com/dynamics365/business-central/dev-itpro/developer/analyzers/appsourcecop-as0035), and [AS0040](https://learn.microsoft.com/dynamics365/business-central/dev-itpro/developer/analyzers/appsourcecop-as0040) on pages whose source tables jave been moved tables to another extension, for instance 'No. Series'.

## Miscellaneous

- Fixed an issue where race conditions would occur if a code action that is invoked on project or workspace scope tried to change large number of files.
- Fixed an issue that caused the runtime to fail, when calling methods from extended interfaces on an instance of the derived interface.
