Migrating Activities to .NET 6

This page offers an overview of how to migrate your custom .NET Framework activities to .NET 6 for use in projects with the Windows compatibility available starting with Studio 2021.10.6.

We will use the sample MathSquareOfSum .NET Framework activity documented on the Creating Activities With Code (Legacy) page as an example for a migration to .NET 6 that targets Windows while also maintaining compatibility with .NET Framework for Windows - Legacy projects.

Step 1: Migrate the project to the new SDK-style format and add the net6.0-windows target

A project that is using the .NET Framework project format must be migrated to the new SDK-style format. For more information, see the Microsoft documentation . Package references must be declared in the .csproj file as opposed to packages.config .

• In Solution Explorer, right click the project and select Unload Project .
• Copy references and clear everything from the .csproj file.
• Manually update the .csproj file to the new format.
• Add the target framework net6.0-windows .
• Mark the original references as net461 only by adding a condition.
• Add a new reference section with conditions for net6.0-windows . You must declare the following WWF dependencies for .NET: UiPath.Workflow.Runtime, UiPath.Workflow, System.Activities.Core.Presentation, System.Activities.Metadata. Make sure all your dependencies support .NET. You might need to find newer package versions or replacement packages.
• In Solution Explorer, right click the project and select Reload Project .

The file should look as follows.

• Step 2: Build the solution

Make sure you test the project for errors before attempting to build it.

• Step 3: Create a NuGet package

Create a NuGet package using NuGet Package Explorer, as described in Creating Activities With Code (Legacy) .

• Launch NuGet Package Explorer and click Create a new package (Ctrl + N) . A split-window is displayed which shows Package metadata and Package contents . We need to add all dependencies in the latter section.
• Right-click inside the Package contents section. A context menu is displayed.
• Click Add lib folder . Notice a new lib item is created in the Package contents section.
• Add .NET Framework folder > v4.6.1
• Add .NET folder > v6.0-windows
• net461 - MathSquareOfSum.dll
• net6.0-windows - MathSquareOfSum.dll
• Rename the folder net6.0-windows to net6.0-windows7.0 .
• With the file selected, access the Edit menu and select Edit Metadata . The left panel is now fitted with editable metadata fields.
• Edit the metadata fields as needed.

• Click the green check mark button in the top-left corner save all changes.
• Select File > Save As to save the new file.

Migrating Activities to .NET 5/6

I’m following the steps described here to migrate to .NET 6:

But none of the mentioned packages are available on the respective versions posted there.

I also face the same issue with .NET 5, none of the versions informed on the documentation did get resolved.

Seeing the Visual Studio logs about the attempt to resolve the System.Activities.Core.Presentation dependency, the nearest version available is an alpha version:

Severity Code Description Project File Line Suppression State Error NU1102 Unable to find package System.Activities.Core.Presentation with version (>= 6.0.0-20220318.2) Found 3 version(s) in MyGet-UiPathDev [ Nearest version: 1.0.0-alpha003 ] Found 1 version(s) in MyGet-Workflow [ Nearest version: 1.0.0-alpha004 ] Found 0 version(s) in Microsoft Visual Studio Offline Packages Found 0 version(s) in nuget.org Found 0 version(s) in Stride

Am I missing some package source here?

@alexandru @loginerror @Pablito do you guys know something about it?

It is already there:

You can also perform a manual search directly on the official feed and you will notice the version on the documentation simply does not exist.

It seems the version informed on the documentation are not public.

@alexandretperez Did you find any solution for the above System.Activity package issue?

Hi @Venkat_A

Yes, I don’t remember exactly what the source I used are, but definitely they are among these:

I have tried this link . unfortunately , it is not working for me. If someone successfully completed the migration, share your experience will helpful to me and others.

Advance Thank you Balamurugan.S

Activity Enrichment in ASP.NET Core 6.0

Jimmy Bogard

Waaaaay back in the ASP.NET Core 3.1 days, I wrote about increasing the cardinality of traces using Tags and Baggage . You could write code in your controllers, filters, or application code to be able to add custom information to traces to help find these traces more effectively:

There is a challenge with this approach in this it uses the Activity.Current property, an AsyncLocal static property on the Activity class. This value might not be the activity you'd actually want to modify. If you have some other filter that creates an Activity :

Then the Activity.Current property isn't the activity of the incoming web request, but something else altogether. If you're intending to add details to the incoming request's span, you're not guaranteed to get the correct Activity .

This got a bit easier with ASP.NET Core 6.0 and the inclusion of a new Request Feature to access the current activity . We can request the IHttpActivityFeature from the current HttpContext to access the Activity associated with the current request:

From the IHttpActivityFeature , we can add tags, baggage, events, or just generally inspect the current span. If we want to start a new activity intentionally parented from this one too, that's possible.

It's only available from anything that has access to HttpContext , which in turn is available in different means depending on what code location you need it at.

This also inspired a similar feature in my NServiceBus.Extensions.Diagnostics package, to be able to modify the exact Activity of the incoming/outgoing message:

And then this tag shows up directly in our traces:

Just like you might add additional log context values for your logs, you would add these custom tags to provide activity/span enrichment for better debugging and searchability.
