Azure-functions-host: Functions do not work with .NET Standard libs

[timheuer]

When authoring an Azure Function and use a .NET Standard library, it fails. In working through an investigation with .NET team, it appears that Functions is not using Binding information to make it work.

Even with some workarounds (https://github.com/dotnet/standard/issues/481) generating the binding config itself, it appears Azure Functions runtime is not using that information.

Sample repro setup: https://github.com/timheuer/func-plus-standard

Repro steps

Provide the steps required to reproduce the problem:
(using Visual Studio 2017)

1. Create new Azure Function
2. Create Function HttpTrigger
3. Add to solution a .NET Standard library
4. In the NET standard library, add some code
5. In the Function, add a reference to the .NET Standard lib
6. Run the Function and hit the endpoint.

Expected behavior

The code from the Standard library will work just fine (.NET Standard 1.6 is compatible with NETFX 4.6.1).

Actual behavior

Exception:

For more details, in order to use .NET Standard 1.5 or 1.6 libraries on .NET Framework 4.6.1, binding redirects are required. We've hacked the project file to force the generation of binding redirects for the Azure Function project (which is disabled by default because it's a class library) the file isn't being deployed next to the DLL but a higher level. That seems to be a result of the way the Azure Functions SDK builds the output as all binaries are in a nested bin folder.

However, even after manually copying the file to a the nested folder it doesn't seem to have any effect. I don't know how Azure Function is hosting the customer's function but this makes me believe they don't create a separate app domains and thus don't/can't honor the binding redirects listed in that app.config file.

One way to address that issue is by adding the binding redirects to whatever process is the Azure Function host.

Thank you @timheuer and @terrajobst for the details!

Your assumption is correct. Currently, user assemblies are loaded in the default/ASP.NET app domain and the actual application (runtime) assemblies reside in a shared location on the worker, which is where the web.config with our defined binding redirects come from and as you found, we don't support user defined binding redirects.

I'll assign this to the current milestone so we can have the fix deployed with the next release.

[terrajobst]

Excellent!

FYI: You can create the proper list of binding redirects by creating a console app targeting .NET Framwork 4.6.1 and then adding a reference to a .NET Standard 2.0 project. Here is the full list:
