Failed to resolve assembly 'Microsoft.AspNetCore.Mvc.Core, Version=3.1.0.0" when building Azure Function v3

Question

I have an Azure Function v3.1.

On my machine (macOS + Visual Studio Mac / Jetbrains Rider), it fails to build with the following error:

Error : Mono.Cecil.AssemblyResolutionException: Failed to resolve assembly: 'Microsoft.AspNetCore.Mvc.Core, Version=3.1.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'

Here is the complete callstack:

Here is the content of my csproj (I followed the recommendations regarding AspNetCore 3.1):

Question

Why is the pipeline unable to build the project?

Update 1

After cleaning the solution output and cleaning the packages folder on my machine, the build fails on my machine as well.

Update 2

It fails when it is trying to generate the Azure Functions output:

2>Target "_GenerateFunctionsPostBuild" in file "/Users/christophe/.nuget/packages/microsoft.net.sdk.functions/3.0.9/build/Microsoft.NET.Sdk.Functions.Build.targets" from project "AccountManager/src/AccountManager/AccountManager.csproj" (entry point):
       Using "GenerateFunctions" task from assembly "/Users/christophe/.nuget/packages/microsoft.net.sdk.functions/3.0.9/build/../tools/netcoreapp3.1/Microsoft.NET.Sdk.Functions.MSBuild.dll".
       Task "GenerateFunctions"
         Function generator path: '/usr/local/share/dotnet/dotnet'
         Microsoft.NET.Sdk.Functions.Generator.dll "AccountManager/src/bin/Debug/netcoreapp3.1/bin/AccountManager.dll " "AccountManager/src/bin/Debug/netcoreapp3.1/ " "False "
  
2>/Users/christophe/.nuget/packages/microsoft.net.sdk.functions/3.0.9/build/Microsoft.NET.Sdk.Functions.Build.targets(32,5): error : Mono.Cecil.AssemblyResolutionException: Failed to resolve assembly: 'Microsoft.AspNetCore.Mvc.Core, Version=3.1.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' [AccountManager/src/AccountManager/AccountManager.csproj]

If I copy the following file into the bin folder, it works:

/usr/local/share/dotnet/packs/Microsoft.AspNetCore.App.Ref/3.1.8/ref/netcoreapp3.1/Microsoft.AspNetCore.Mvc.Core.dll

Answer 1

If you added [FromQuery] or any other attribute to your azure function "controller signture" it could happened , at least that what happened to me...

after I removed the [FromQuery] attribute it came back to life..

I have found this answer that nailed it : https://github.com/Azure/azure-functions-vs-build-sdk/issues/435#issuecomment-656854953
