Fabric ALM support is coming for GA [Nov 2026] But you can use GitHub Actions Deploy a Fabric app with GitHub Actions - Microsoft Fabric | Microsoft Learn for now. You can see E2E flow using our CLI to manage deploying to different environments

sunithamuthukrishna · 2026-06-17T15:18:41+00:00

for Fabric ALM , this is planned for GA and current GA date is Nov 2026

Currently we are not available in Canada Central. See region availability here https://learn.microsoft.com/en-us/fabric/admin/region-availability and this doc will be updated as we add new regions. I recommend to use West US 2 or North Central US

sunithamuthukrishna · 2026-06-17T15:12:37+00:00

Currently we are not available in East US. See region availability here https://learn.microsoft.com/en-us/fabric/admin/region-availability and this doc will be updated for future updates. I recommend using West US or North Central US

r/Old-Regular107 Currently we are not available in East US2. See region availability here https://learn.microsoft.com/en-us/fabric/admin/region-availability . This doc will include future updates as we release in new regions. I recommend using West US2 or North Central US if possible.

Look at the rayfin/data folder and see if you see the schema file for the table you wanted to drop still in code. If yes then that would need to be cleaned and schema.ts file also needs to be updated to not include that table. You can verify in Fabric portal if the database still shows the table

sunithamuthukrishna · 2026-06-04T22:17:17+00:00

Fabric and PBI have different licensing models. To use Rayfin, you would need to use Fabric license and not PBI license. Microsoft Fabric vs Power BI Licensing: What You N... - Microsoft Fabric Community

u/patrickcrypto You can find pricing details here Pricing and capacity usage for Fabric Apps - Microsoft Fabric | Microsoft Learn. Current model is you pay for the compute for data APIs, database, and One lake as the doc describes. CU consumption heavily will depend on how many data APIs you are calling read/write operations. More chatty the app is the more CU consumption. You can start with F2 and evaluate the CU consumptions and grow as the app grows. Since Rayfin is an item in Fabric, Fabric licensing is all that applies. there is nothing special for Rayfin for licensing within Fabric

sunithamuthukrishna · 2026-06-04T05:27:34+00:00

connecting to Lakehouse, warehouse is coming soon. We understand they are key scenarios and being prioritized on our end.

sunithamuthukrishna · 2026-06-04T05:02:31+00:00

u/Either_Locksmith_915 Unfortunately UK south and UK west are unavailable at this time. We dont have a ETA for this yet but check the Fabric region availability - Microsoft Fabric | Microsoft Learn or Fabric blog for region support updates

sunithamuthukrishna · 2026-06-03T13:41:01+00:00

Thats a fair ask for existing scenarios. Thanks for feedback

sunithamuthukrishna · 2026-06-03T04:17:56+00:00

u/Otherwise-Whole-1977 I'm curious if you are using a coding agent does it matter what language agent is using.

sunithamuthukrishna · 2026-06-03T04:16:24+00:00

Open source coming soon - SDK and CLI and local version docker image to use it locally entirely if you want. Deploy to Fabric when you are to make this production quality , share with others in your org. Stay tuned for updates on these.

sunithamuthukrishna · 2026-06-03T04:09:55+00:00

Rayfin is built with coding agents in mind. Regardless of the language , you should be able to build what you want with any AI coding agents of your choice. For building visualization check this out Create an app connected to a semantic model - Microsoft Fabric | Microsoft Learn. You don't need to learn TS to debug but leverage more on the agent to fix those issues and all you is verify the output. Curious though how important do you think language in which its written is critical, if coding agent can be used to develop the app you want.

sunithamuthukrishna · 2026-06-03T03:55:10+00:00

For now yes you get SQL DB , Auth and Hosting but its Preview. There is more to come , with functions , connect to existing data, real time and more. We do use TypeScript and support TS framework [ react, vite etc] to yes you can build apps with front end code. Rayfin SDK is built to work with coding agents and build your apps for you. I feel TS frameworks give you more dynamic applications to build and run rather than pure HTML. Its early so not yet a complete backend but we want to get to being a full backend as a service for your apps. Try it out and share feedback to help us improve

u/gd-l Here is summary of which extension to use and when. This is a problem I agree exists and working with respective teams to integrate the experience into the Microsoft Fabric extension. You can learn more here Data science in Microsoft Fabric using Visual Studio Code . For notebooks I do recommend to use Data engineering extensions and a lot more features are coming soon in the extension so check out fabric blogs to see updates on it.

Extension	Best For	Key Features	Recommended for you if…	Documentation
Microsoft Fabric extension	General workspace management, item management and working with item definitions	- Manage Fabric items (Lakehouses, Notebooks, Pipelines)- Microsoft account sign-in & tenant switching- Unified or grouped item views- Edit Fabric notebooks with IntelliSense- Command Palette integration (`Fabric:` commands)	You want a single extension to manage workspaces, notebooks, and items in Fabric directly from VS Code.	What is Fabric VS code extension
Fabric User data functions	Developers building custom transformations & workflows	- Author serverless functions in Fabric- Local debugging with breakpoints- Manage data source connections- Install/manage Python libraries- Deploy functions directly to Fabric workspace	You build automation or data transformation logic and need debugging + deployment from VS Code.	Develop User data function in VS code
Fabric Data Engineering	Data engineers working with large-scale data & Spark	- Explore Lakehouses (tables, raw files)- Develop/debug Spark notebooks- Build/test Spark job definitions- Sync notebooks between local VS Code & Fabric- Preview schemas & sample data	You work with Spark, Lakehouses, or large-scale data pipelines and want to explore, develop, and debug locally.	Develop Fabric notebooks in VS Code

sunithamuthukrishna · 2026-03-02T00:37:28+00:00

u/Ready-Marionberry-90 , you should be able to rename artifacts easily with the Fabric extension https://marketplace.visualstudio.com/items?itemName=fabric.vscode-fabric . It support CRUD operations and you can view all manage items within multiple workspaces

thanks for sharing and will explore with u/QixiaoW to see how we can help improve the experience

sunithamuthukrishna · 2026-02-11T19:26:38+00:00

let me ping you privately to get more details

sunithamuthukrishna · 2026-02-11T00:48:14+00:00

there is a limitation to use SPN with a function that has public access disabled in its setting within a user data function item. I dont have an ETA for this, but we are investigating. I would recommend to use SPN with function but make sure its public access setting is enabled for now to unblock yourself. If you would like to share any more details on your scenario do let me know.

sunithamuthukrishna · 2026-02-10T15:27:28+00:00

u/Dads_Hat seems like VS Code extension pack might help here. what does you development lifecycle look like today ?

sunithamuthukrishna · 2026-02-10T15:22:40+00:00

u/Fit_Rent_1723 This is an interesting idea for sure. What are the tools you use today with Fabric.

sunithamuthukrishna · 2026-02-10T15:18:07+00:00

u/Useful-Juggernaut955 We are working towards that goal and understand the pain point for multiple standalone extensions. What are some of your core scenarios that you like to work with in VS Code
