The type could not be found. You may need to provide additional assemblies.

Informations:

[Using WSL2]

dotnet avro --version
Chr.Avro.Cli 7.0.4

dotnet --list-sdks
3.1.302 [/usr/share/dotnet/sdk]

[Using Windows]

dotnet avro --version
Chr.Avro.Cli 7.0.4

dotnet --list-sdks
3.1.406 [C:\Program Files\dotnet\sdk]
5.0.103 [C:\Program Files\dotnet\sdk]

When I try to run the readme example: dotnet avro create -t System.Int32 I got this message: The type could not be found. You may need to provide additional assemblies.

How could I solve this ?

[alefcarlos]

The same thing happens when I try to create using my own assemblies.

dotnet avro create -a src/Super.GlobalPlatform.Authorizer.Events/bin/Debug/netstandard2.0/Super.GlobalPlatform.Authorizer.Events.dll -t Super.GlobalPlatform.Authorizer.Events.AuthorizationRequestApprovedEvent

I got this:

The type could not be found. You may need to provide additional assemblies.

Thanks for the detailed report. I think this might be the same thing as #127, although I’m not sure why it doesn’t work to generate a schema for your netstandard2.0 library (could be that if the build SDK is different, building schemas for mscorlib fails?). Will investigate further and tag as a blocker for 8.0.0.

@dstelljes, I could generate using dotnet avro create -a System.Runtime -t System.Decimal, but without System.Runtime it doesnt work.

I tried this on Docker image as well and the same problem has ocorrued.

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-buster AS build

RUN dotnet tool install Chr.Avro.Cli --global

ENV PATH="/root/.dotnet/tools:${PATH}"

RUN dotnet avro create -t System.Int32

[dstelljes]

Interesting... does it work to generate a schema from your own assembly if you explicitly load System.Runtime as well?

dotnet avro create -a System.Runtime -a src/Super.GlobalPlatform.Authorizer.Events/bin/Debug/netstandard2.0/Super.GlobalPlatform.Authorizer.Events.dll -t Super.GlobalPlatform.Authorizer.Events.AuthorizationRequestApprovedEvent

[alefcarlos]

@dstelljes ,

dotnet avro create -a System.Runtime -a src/Super.GlobalPlatform.Authorizer.Events/bin/Debug/netstandard2.0/Super.GlobalPlatform.Authorizer.Events.dll -t Super.GlobalPlatform.Authorizer.Events.AuthorizationRequestApprovedEvent

My bad, should have been

dotnet avro create -a System.Runtime src/Super.GlobalPlatform.Authorizer.Events/bin/Debug/netstandard2.0/Super.GlobalPlatform.Authorizer.Events.dll -t Super.GlobalPlatform.Authorizer.Events.AuthorizationRequestApprovedEvent

[alefcarlos]

Same error :(

The type could not be found. You may need to provide additional assemblies.

[dstelljes]

Shoot, thanks for checking. We should also improve that message; it’d be good to know which type specifically it was failing to find.

[alefcarlos]

hum... I got it, I need to pass all dependency assemblies as well, Im gonna try it.

[davrobles]

First, thank you for this very useful repo,

I'm having the same error, I've iterated the assembly classes and names are correct, when I try to generate It shows this:

The type could not be found. You may need to provide additional assemblies.

dotnet avro create --type AvroCsharpPOC.ExampleClass --assembly bin/Debug/net5.0/AvroCsharpPOC.dll

[dstelljes]

@davrobles, have you tried also passing System.Runtime as an assembly name as suggested above?

dotnet avro create --type AvroCsharpPOC.ExampleClass --assembly System.Runtime bin/Debug/net5.0/AvroCsharpPOC.dll

[davrobles]

@davrobles, have you tried also passing System.Runtime as an assembly name as suggested above?

dotnet avro create --type AvroCsharpPOC.ExampleClass --assembly System.Runtime bin/Debug/net5.0/AvroCsharpPOC.dll

It worked!

I had to change the target to .net core 3.1 and place the System.Runtime before the dll path, didn't work on .net 5 but I see you're already working on that.

Thank you so much @dstelljes

[dstelljes]

Thanks for your patience on this; the 7.1.0 release later today will add net5.0 as a CLI target framework and pull in System.Runtime by default.
