How can we import C# Class in azure function from the external repos?

Question

Can we create the object of the external class in the azure function to use its functionality?

Answer 1

You can define classes in separate files and reference those files using the #load directive as documented here: https://learn.microsoft.com/en-us/azure/azure-functions/functions-reference-csharp?tabs=functionsv2#reusing-csx-code.

You can also reference an assembly where your classes are defined and is documented here: https://learn.microsoft.com/en-us/azure/azure-functions/functions-reference-csharp?tabs=functionsv2#referencing-external-assemblies

Answer 2

Suman Gautam Thanks for posting your question in Microsoft Q&A. I assume, external repos as public NuGet Packages or private feed. You can specify packageSources in the project reference other than public NuGet feed.

For C# script, refer Using NuGet packages doc to add external packages in *.csproj file and follow the steps shared by Sudipta to reference the files/objects. In Isolated model, you can add packageSources in Nuget.Config and package references in *.csproj file and import packages with using statement and the same goes with In process model as well (similar discussion: SO Thread).

Samples for Isolated process samples are available here and other samples here. I hope this helps with your question and feel free to add a comment with additional details if you face issues.
