Add support for Azure Functions

[lars-houtman]

Originally a bug report, however I was made aware this was a feature request. The requested feature is as follows: add support for Azure Function Core Tools to run our Function projects with Aspire in Rider.

Original post:

Describe the bug
When using Rider to start Azure Functions, they are not run with the correct Azure Function Core Tools but with the .net runtime itself.

To Reproduce
Steps to reproduce the behavior:

1. Create a new Aspire solution
2. Create a new Azure Functions project
3. Reference the Azure Functions in your AppHost
4. Add builder.AddProject<Company_FunctionApp1>("fn"); to your AppHost Program.cs
5. Run AppHost

Expected behavior
I expect the Azure Function to start normally. It does so in Visual Studio.

Screenshots
The following exception is thrown and the Function does not start.

System information:

• OS: Windows 11
• .NET version: 8.0
• JetBrains Rider version: 2024.2.3
• Aspire plugin version: bundled 1.3.0
• Aspire workload version: 8.2.0

Extra: the logs from the function when starting the AppHost via Visual Studio are as follows:

Sorry, but this is not a bug but a feature request. The Azure Function project is not a regular dotnet project. It needs to be run using Azure Function Core Tools. This is not yet supported by the plugin.

Oh, apologies. I assumed the target was to work like in Visual Studio. I will rephrase my post.
