I am using the NuGet package Google.Cloud.Firestore which relies on some other packages where type forwarding is used. The forwarded types are not found and result in a MissingMethodException.

The issue occurs when debugging locally in VS Code on macOS. I haven't deployed this yet.

The same code works in a .NET Core console app.

A lot more details at the original issue: googleapis/google-cloud-dotnet#3101

Investigative information

  • Timestamp: Monday June 3th
  • Function App version: 2.0

Repro steps

See original issue above

Expected behavior

Type forwarding is working and no MissingMethodException

Actual behavior

MissingMethodException when this calls into a forwarded type.

Known workarounds

?

I have a simpler repro now - there's no need for the Firestore dependency.

Project file:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>netcoreapp2.2</TargetFramework>
    <AzureFunctionsVersion>v2</AzureFunctionsVersion>
  </PropertyGroup>
  <ItemGroup>

</Project>

Function source:

using Google.Apis.Auth.OAuth2;
using Grpc.Auth;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.Http;
using Microsoft.Extensions.Logging;

using System.Threading.Tasks;

namespace FunctionApp1

    public static class Function1
    {
        [FunctionName("Function1")]
        public static IActionResult Run(
            [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
            ILogger log)
        {
            log.LogInformation("C# HTTP trigger function processed a request.");

            var tokenAccess = new DummyTokenAccess();
            // This succeeds
            tokenAccess.ToCallCredentials();
            // This fails
            tokenAccess.ToChannelCredentials();

            return new OkObjectResult("Passed");
        }
    }

    class DummyTokenAccess : ITokenAccess
    {
        public Task<string> GetAccessTokenForRequestAsync(string authUri = null, CancellationToken cancellationToken = default)
        {
            throw new System.NotImplementedException();
        }
    }
}

Exception:

System.MissingMethodException
  HResult=0x80131513
  Message=Method not found: 'Grpc.Core.ChannelCredentials Grpc.Core.ChannelCredentials.Create(Grpc.Core.ChannelCredentials, Grpc.Core.CallCredentials)'.

This is very odd indeed:

  • There are no different Grpc versions involved. We're compiling against Grpc.Auth 1.21.0 which was compiled against Grpc.Core 1.21.0, and that's the version present in both places.
  • Looking at the IL for the method declaration and the call to it, from the DLLs in the bin directory, they look fine to me:
// Declaration in Grpc.Core, in ChannelCredentials:
.method public hidebysig static class Grpc.Core.ChannelCredentials 
        Create(class Grpc.Core.ChannelCredentials channelCredentials,
               class [Grpc.Core.Api]Grpc.Core.CallCredentials callCredentials) cil managed


// Call in Grpc.Auth, in GoogleGrpcCredentials.ToChannelCredentials:
call       class [Grpc.Core]Grpc.Core.ChannelCredentials [Grpc.Core]Grpc.Core.ChannelCredentials::Create(class [Grpc.Core]Grpc.Core.ChannelCredentials,
                                                                                                                     class [Grpc.Core.Api]Grpc.Core.CallCredentials)

Note that the ToCallCredentials method works. CallCredentials is in Grpc.Core.Api; ChannelCredentials is in Grpc.Core.

I'm going to keep investigating this a bit to see if I can reproduce this without even a Grpc.Auth reference...

Okay, even simpler repro - and an explanation.

First, the project file:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>netcoreapp2.2</TargetFramework>
    <AzureFunctionsVersion>v2</AzureFunctionsVersion>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Grpc.Core" Version="1.21.0" />
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="1.0.24" />
  </ItemGroup>
  <ItemGroup>
    <None Update="host.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
    <None Update="local.settings.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
      <CopyToPublishDirectory>Never</CopyToPublishDirectory>
    </None>
  </ItemGroup>
</Project>

Next, source code:

using Grpc.Core;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.Http;

namespace FunctionApp1
{
    public static class Function1
    {
        [FunctionName("Function1")]
        public static IActionResult Run(
            [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req)
        {
            CreateChannelCredentials(null);
            return new OkObjectResult("Passed");
        }

        private static ChannelCredentials CreateChannelCredentials(CallCredentials callCredentials) =>
            ChannelCredentials.Create(new SslCredentials(), callCredentials);
    }
}

This fails with the same MissingMethodException when you try to execute CreateChannelCredentials, when the JIT compiler works on that method - because it can't find the method.

The problem is that it's not loading Grpc.Core 1.21.0 at all - it's using 1.18.0 which is in C:\Users\skeet\AppData\Local\AzureFunctionsTools\Releases\2.22.0\cli\

If you update the cli directory to contain the relevant files from Grpc.Core and Grpc.Core.Api, and update func.deps.json accordingly, it all works - including Google.Cloud.Firestore.

So basically, this is a problem for any function needing to use a version of Grpc.Core later than the one embedded in the CLI application.

Behind the scenes the following sequence occurs.
. You compile and include the azure functions sdk, vs finds that it you load 1.21 all the binary dependencies can be satisfied, so complies without error.
. The project starts to run
. Azure functions host starts, and loads 1.18
. Azure functions loads your functions
.net runtime notes that the library is present in the app domain and so can't load another copy.
. At runtime you try to use a 1.21 feature and exception as noted.

This is because the functions runtime in azure loads that specific version of the library , but the announced dependencies are often vague. If you use features from a library newer that what is present things fail in the way described.
The same goes of you assume bugs are fixed.
This happens for other libraries as well, e.g. newtonsoft.json #4049 (comment)
For the json dependency they fixed this by causing the functions sdk to depend on the exact version loaded by the runtime, but this block including in your prophecy any library that includes any other version. Probably a more helpful failure mechanism imo).

Will investigate this as the version packaged with the CLI shouldn't cause this issue, so looks like there's a bug here. Do you happen to know it this is happening outside of the context of the CLI?

This was just in case you had tested this on Azure or in one of the container options. Wasn't really expecting that to be the case, but thought I'd ask.

I'll assign this to the next sprint and take a closer look to see what is causing the issue.

@DJ4ddi DJ4ddi commented Nov 6, 2019

I ran into the issue described on StackOverflow, leading me here.

Locally, both manually including a more recent package version of Grpc.Core via NuGet and the workaround posted by @andreujuanc worked. Unfortunately, neither did the trick for the remote end in the Azure cloud. Copying the dependency JSON changes nothing, while upgrading the package changes the original "Could not load type" error to
Method not found: 'Grpc.Core.ChannelCredentials Grpc.Auth.GoogleGrpcCredentials.ToChannelCredentials(Google.Apis.Auth.OAuth2.ITokenAccess)'.
So, while it does make a difference, I still can't run the function properly. Interestingly, also manually including Grpc.Core.Api restores the original error
Could not load type 'Grpc.Core.CallCredentials' from assembly 'Grpc.Core.Api, Version=1.0.0.0, Culture=neutral, PublicKeyToken=d754f35622e28bad'.
And in some combination of workarounds, I also managed to kill the library entirely, as indicated by the fact that grpc_csharp_ext.x86.dll failed to load.

Needless to say, I'm a bit confused. Why does basically every combination of proposed solutions work locally, but none of them solve the problem for the cloud runtime (which, according to some reports, shouldn't even be affected in the first place)?

@jskeet jskeet commented Nov 6, 2019

@DJ4ddi: If you've upgraded to Grpc.Core version 2.x, that would definitely cause problems for anything expecting 1.x, including (currently) all the Google Cloud client libraries. (These will soon be upgraded to Grpc.Core 2.x - at which point you won't be able to use them in the same app with anything 1.x-based, of course.)

The symptoms were the exact same when manually installing version 1.22.1 or 1.22.0 (the exact version referenced by Google.Cloud.Dialogflow.V2).

@wikes82 me too! But only if it runs through the publish on Azure DevOps. I've got a ticket open with them now about that. If I right click and tell it to do a zip deploy from VS (Windows) it works in Azure Functions for me with the following code:

	<Target Name="PostBuildWindows" AfterTargets="PostBuildEvent">
		<!-- https://github.com/Azure/azure-functions-host/issues/3568 -->
