This post is part of the New Functionality In Microsoft Dynamics 365 Business Central 2025 Wave 1 series in which I am taking a look at the new functionality introduced in Microsoft Dynamics 365 Business Central 2025 Wave 1.

The 20th of the new functionality in the Development section is running objects in actions defaults to UI descriptors on target object.

When adding actions in AL, developers can specify properties like Caption, Tooltip, AboutText, and AboutTitle. Sometimes actions are just used to run specific objects, so to ensure consistency and reuse with these, such actions now default to the Caption, Tooltip, AboutText, and AboutTitle of the targeted object. This also ensures that existing actions will benefit from Tooltip, AboutText, and AboutTitle being defined on the targeted object.

Feature Details

Actions that have the RunObject property specified will use the Caption, ToolTip, AboutText, and AboutTitle properties of the targeted application object, if none of these properties is specified on the action itself. This ensures consistency and reuse, even for existing actions, while at the same time allowing overriding those values by specifically setting them on the action itself.

In support of this, the ToolTip property has also been added to reports.

The 19th of the new functionality in the Development section is generate launch json file from the web client.

One of the feedback items on the Open in Visual Studio Code has been the request to quickly generate a launch configuration matching the specific environment. In this release Microsoft have added actions in the web client that do exactly that, making it easier to create a launch configuration to investigate or debug a specific environment in Visual Studio Code.

Feature Details

Now, directly within the web client, you can generate a matching launch.json configuration for the specific environment, making it easier to investigate or debug a specific environment from Visual Studio Code.

There are two options in the Business Central web client to generate the launch.json configuration.

You can use the Generate launch configurations for this environment action in the Troubleshooting section of the Help & Support page.

In addition, you can use the Generate launch configurations action in the Develop in VS Code action group on the Extension Management page menu.

The 18th of the new functionality in the Development section is create lists and dictionaries of interfaces in AL.

In the Business Central AL language, dictionaries and lists are powerful data structures that offer efficient lookup of key-value pairs and ordered collections, and both allowing managing collections of data dynamically. Microsoft are now adding the ability to have lists and dictionaries of interfaces, providing more flexibility and power when you work with interface abstractions.

Feature Details

You can now create lists or dictionaries of interfaces.

The syntax follows these patterns, aligned with creating a List or Dictionary of a simple type:

• List of [Interface IFoo]
• Dictionary of [; Interface IFoo]

In the System Application, you can find the complete examples of using a list of interfaces in the Telemetry Logger.

The following examples illustrate creating lists and dictionaries with interfaces.

Feature Details

Microsoft have added the ToText method to simple types (BigInteger, Boolean, Byte, Date, DateTime, Decimal, Duration, Guid, Integer, Label, Time, Version) for easy conversion to text.

For advanced formatting options, you should continue to use FORMAT.

The 16th of the new functionality in the Development section is use new IncStr parameter to change integers by more than 1 in string variables.

For some time you’ve been able to increase a positive number or decrease a negative number inside a string variable by 1 using the IncStr method on Text types. This is useful when handling iterations, for example, involving number series. If you needed to make a change of more than 1, however, you had to write extensive custom logic. To help in these scenarios, the IncStr method now supports a new optional increments parameter to change more than 1.

General Availability: Apr 2025

Feature Details

A new overload of the IncStr method is added to support an arbitrary increase or decrease of a number in a string variable. This allows for incrementing number series or other similar series by more than one position in one go.

When decreasing a positive number, use a try function to catch cases where the string can’t be decreased further. Format-wise, when decreasing, leading zeros will be added as applicable.

The example shows incrementing the integer 99 in the AText string variable to 109 in a single call, by using the new IncStr method overload with an increment parameter of 10.

The 15th of the new functionality in the Development section is self-service App Key Vault onboarding for AppSource apps.

AppSource apps for Business Central can read secrets from Azure Key Vault owned by the publishing partner. However, in order for this feature to be available to a partner’s AppSource app, they have had to go through a manual process and reach out to us, which could lead to waiting times—and Azure Key Vault availability required a new version of the app after registration. To streamline the process, Microsoft have now made onboarding to Azure Key Vault part of the AppSource submission itself, which also implies that the app can immediately use its Azure Key Vault.

Feature Details

Partners who want to register a key vault for their app no longer need to send an email to us and wait until Microsoft register their Entra Tenant Id with their app.

Instead they must:

• Grant read permission to Microsoft’s Dynamics 365 Business Central ISV Key Vault Reader app.
• Create a special secret in their respective key vault named AllowedBusinessCentralAppIds. This secret should contain the appIds of every app that will have access to the given key vault. For multiple apps, separate by a comma ‘,’.

Follow this path to reduce the registration waiting time and make registration faster and easier.

Note that AppSource apps that already have registered their Entra Tenant Id should also introduce the special secret before submitting higher versions of their apps. The absence of this reserved AllowedBusinessCentralAppIds secret will likely result in a submission failure in the future.

The 14th of the new functionality in the Development section is use new properties on a report layout.

The new properties added to report layouts significantly enhance the flexibility and functionality of your reporting. The ObsoleteState property allows developers to mark layouts as deprecated, ensuring a smoother transition and better management of future updates. Meanwhile, the ExcelLayoutMultipleDataSheets property enables more complex and customized Excel reports without compromising existing layouts. These enhancements streamline your reporting processes, reduce the risk of errors, and ultimately save time and resources for your business.

Feature Details

The following new properties are available for report layouts:

• ObsoleteState
• ExcelLayoutMultipleDataSheets

With the ObsoleteState property, a developer can signal that a layout is deprecated and will be removed in a later release. The property is shown on the Report Layouts page.

With the ExcelLayoutMultipleDataSheets property, a developer can override the global property defined on the report object to the layout context. For reports where the global property ExcelLayoutMultipleDataSheets wasn’t set (and therefore interpreted as False), a developer can add Excel layouts that use the ExcelLayoutMultipleDataSheets feature without adding the risk of breaking existing Excel layouts that users added.

The 13th of the new functionality in the Development section is work with multiline strings in AL.

When developing AL, very long strings are sometimes used. Previously these had to be written in one line, making it hard to easily read content. In this release, Microsoft have added support for writing out strings spanning multiple lines, allowing developers to format the string content in a more human readable form. This especially helps when working with more structured string content, like JSON content.

Public Preview: Apr 2025
General Availability: Apr 2025

Feature Details

You can now write a string in AL that spans multiple lines by prefixing it with @. This allows you to write the string in a more human readable form—for example, when the content is a structured format like JSON content.

When using this option, remember that any added white space (such as trying to indent lines) will become part of the string, and is therefore not recommended.

Below is an example of using this capability when assigning a JSON template structure to a text variable. Notice the use of @ at the beginning of the string to indicate a multiline string.

The 12th of the new functionality in the Development section is validate certificates on external web service endpoints called from AL HttpClient.

This new feature enhances the security of HTTP calls in your AL applications by validating all server certificates used for outgoing web service calls. With certificate validation enabled by default, you can ensure a higher level of trust and security in your communications. If needed, you have the flexibility to selectively disable certificate validation for specific calls, and a new telemetry event helps you debug any failures. By providing robust security measures and debugging tools, this feature adds value by protecting your business from potential security threats and ensuring smooth, secure operations.

General Availability: Apr 2025

Feature Details

To enhance security of HTTP calls from AL, the AL runtime now validates all server certificates used when calling a web service endpoint from the HttpClient datatype. Certificate validation is enabled by default. A server certificate is installed on the endpoint side—it’s not the certificate you attach to a request in AL.

If an app or per-tenant extension needs to selectively disable certificate validation, a new property has been added to the HttpClient datatype that allows the AL code to disable server certificate validation for the outgoing web service call.

If the publisher of an app or per-tenant extension needs to debug failing HTTP calls due to server certificates that fail to be validated, a new telemetry event has been added and will be emitted in case of certificate validation failures.

The ability to disable certificate validation is controlled by a feature management key to allow app and per-tenant extension publishers to modify their code. In version 27, certificate validation will be enabled by default without the ability to switch it off.

The 11th of the new functionality in the Development section is search, navigate and use app symbols as context for GitHub Copilot.

You can now search AL objects from downloaded symbol packages from within Visual Studio Code. This makes it much easier to find related objects, whether for inspection, troubleshooting, or as inspiration. It can even be used as context when using GitHub Copilot to get better suggestions based on existing code.

Feature Details

You can now search objects from downloaded symbol packages via the ‘Open Symbol by Name’ functionality (Ctrl+T).

This makes it much easier to find objects, and open the source, if the symbols include source code.

It also empowers GitHub Copilot in Visual Studio Code. You can open the source for selected, related symbols to use as context for Copilot Studio when you write your own code, to get better suggestions.

The performance of searching workspace symbols has, furthermore, been improved to support the larger amount of available symbols.
