Microsoft.CodeAnalysis v3.4.0 package appears to be empty is this correct?

[TehWardy]

Version Used:
3.4.0 : https://www.nuget.org/packages/Microsoft.CodeAnalysis

Steps to Reproduce:

1. Updated existing version to this version through reference
2. Nuget pulls package
3. look in package folder

Expected Behavior:
Dll file for use in project

Actual Behavior:
No dll file in package.

When app runs, runtime error of ...

Could not load file or assembly 'Microsoft.CodeAnalysis, Version=3.4.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified.

... is provided by framework.

I am also referencing packages ...

• Microsoft.CodeAnalysis.CSharp.Scripting
• Microsoft.CSharp

... which in turn appear to be referencing their own stack of dependencies, those packages appear to have libs in them.

Appears to be the cause of issue dotnet/core#4390

Microsoft.CodeAnalysis is a metapackage that contains no dlls at all. instead it references all other roslyn packages. It exists as an easy way to take a dependency on a specific version of all roslyn assemblies.

Microsoft.CodeAnalysis.Common is a set of common libraries that all other roslyn packages have a dependency on. It is unlikely you ever need to reference this package directly.

From reading through the issues you posted elsewhere @TehWardy this may be an issue with the Azure Functions and which set of runtimes/dependencies it supports. I would file an issue on https://github.com/Azure/azure-functions-host

Thanks @jmarolf ... surely if that dll is not really a thing then I wouldn't be getting ...

Could not load file or assembly 'Microsoft.CodeAnalysis, Version=3.4.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified.

... it's like it's looking for that specific dll (hense my confusion here).
I will do as you say though, and drop this in to the functions host team.

Sooooo .... I did some more testing ... created a new azure functions v3 project on top of .Net Core 3.1 and added the package Microsoft.CodeAnalysis.CSharp.Scripting v3.4.0

then built and ran it.
Didn't get this problem, so I took a look in the build output folder and ...

... i'm confused ... clearly this dll is a thing and actually exists somewhere.
When I apply the changes to my main solution (match up the project file to reference the same stuff, same versions, ect) and run that, I still get this exception.

[TehWardy]

This is now confusing me ... when it ran fine before that was my build output, since I added the code to actually use from Azure/azure-functions-host#5796 It's no longer spitting out the same output ...

[TehWardy]

Ok on the functions ticket i've updated it to reflect that this problem only happens when I wrap this code in the Azure Functions framework, a standard console app doesn't suffer this problem so IMO this points to it defintely being a Functions Hsot issue.

[jmarolf]

To further clarify Microsoft.CodeAnalysis.Common is the nuget package that contains Microsoft.CodeAnalysis.dll (not the Microsoft.CodeAnalysis package).

Good to know ... thx :)
