Customising the Umbraco Pipeline

The excuse for today's post is I need somewhere to write up some findings from an Umbraco support case I've been looking into. A customer was using an external library that provided middleware that needed to be configured between UseRouting() and UseEndpoints() . Which isn't a problem if you have full control over the contents of the StartUp.cs class, but it's not so easy when Umbraco is doing some of this setup for you. Thanks to Benjamin Carleski from the Umbraco community who figured this out and shared it in this forum conversation . Nothing is really different from his answer on setting up CORS, but in this post I can more easily and permanently share the sample code. Assuming we have a library that requires a typical "Add..." addition in the ConfigureServices method and "Use..." in the Configure method of Startup.cs . First we need a pipeline filter class: Then a class responsible for inserting this filter in the pipeline: An

Pushing Updates to a PR

This is unashamedly a "note to self" post... something I occasionally need to do, and always need to ask about or look-up. As a maintainer of an open-source project on GitHub, an incoming PR from a contributor's fork that needs some minor changes before merging can be dealt with by committing changes directly to the branch on the fork, if the contributor has allowed edits from maintainers . To checkout the branch locally: git fetch origin pull/[pr id]/head:[branch name] git checkout [branch name After making changes, to push them back to the branch on the fork: git remote add [remote name] addremote [fork url] git push [remote name] [branch name]

Getting Submitted Form Data in Umbraco Forms

With Umbraco Forms, you can configure a page to redirect the user to once a form has been submitted. A question came to me about how on that page we can get information about the form just submitted, as well as details of the record created from submission. I'll share the answer here for future reference. We can make use of a couple of TempData values that are set automatically by Umbraco Forms (documentation here ). UmbracoFormSubmitted - The Guid of the Form Forms_Current_Record_id - The Guid of the Record created from the form submission The following code example, valid for Umbraco 8, shows how this data can be retrieved. For illustration purposes, I've implemented it directly in the template for the page the user is presented with after the form is submitted. For production code, likely this would be better in the controller of a hijacked route .

Service Location in Umbraco 9

I should probably start this post with a caveat saying, "don't do this... unless you really, really have to!" With Umbraco 9, built on .NET 5, we have support for the dependency injection design pattern , and where possible, the recommedation is to use that, to promote testability and other best practices. Within the Umbraco CMS source code though, and also in the add-on products Forms and Deploy, we have found it necessary to use service location in a couple of instances. Primarily, to avoid breaking changes. For example, when a public class requires a new dependency, we don't just add it to the constructor as that would potentially break integrations that are already using it. Instead we obsolete the existing constructor, create a new one with the additional parameter, and have the original constructor delegate to the new one - using service location to provide the parameter for the added dependency. In code it looks like this: To use, you need to be ref
