Since version 1.2.0 an issue occurs when using System.IO.Compression.ZipArchive (an possibly other native implementations).
After uninstalling version 1.2.0 and installing 1.1.0, the issue was resolved.

This is the piece of code, that throws an exception

using(var zipFile = new System.IO.Compression.ZipArchive(zipStream, System.IO.Compression.ZipArchiveMode.Create)){
    // Get artifacts from project
    var artifactDirectory = Path.Combine(project.FullName, "bin", configuration);
    if (Directory.GetDirectories(artifactDirectory).Any(e => e.EndsWith("net5.0"))){
        artifactDirectory = Path.Combine(artifactDirectory, "net5.0");
    }
    // Copy all artifacts to the bin/ directory
    foreach(var artifactFile in Directory.GetFiles(artifactDirectory, "*.*", SearchOption.AllDirectories)){
        var entrySubstring = Path.Combine("bin", artifactFile.Substring(artifactDirectory.Length + 1));

        // Following line (41) throws Exception -------------------------------------------------------------------------------
        using(var writeStream = zipFile.CreateEntry(entrySubstring).Open()){
            using (var readStream = File.OpenRead(artifactFile)){
                readStream.CopyTo(writeStream);
                Console.WriteLine("Creating '" + entrySubstring + "' from '" + artifactFile);
            }
        }
    }
// ...
}

@hrumhurum Another issue related to assembly loading. Have not looked into the details, but seems related to native dlls

Maybe related? dotnet/corert#5496

A naïve approach trying to reproduce the issue works as expected.

test.csx:

using System.IO.Compression;

var ms = new MemoryStream();
var cs = new DeflateStream(ms, CompressionMode.Compress);

var bw = new BinaryWriter(cs);
string s = "Test Test Test Test Test Test Test Test Test Test Test Test Test";
bw.Write(s);
bw.Flush();

bool result = ms.Length > 0 && ms.Length < s.Length;

Console.WriteLine(result ? "OK" : "NOK");

The output of dotnet-script test.csx:

OK

Running dotnet-script --version renders:

1.2.0

@SvenEssentry, can you please send a reproduction sample?

@hrumhurum

One thing I have noticed.

If a script does this

var context = AssemblyLoadContext.CurrentContextualReflectionContext;

It will return null. Should this be the ScriptAssemblyLoadContext

It should not return null. Are you trying this in interactive mode?

using System.Runtime.Loader;
var loadContext = AssemblyLoadContext.CurrentContextualReflectionContext;
Console.WriteLine(loadContext.GetType());

Loading

var loadContext = AssemblyLoadContext.CurrentContextualReflectionContext;

Was able to reproduce it with dotnet-script 1.2.0 global tool installed, but not with locally built binaries.

Upon closer inspection, it turned out that %USERPROFILE%\.dotnet\tools\.store\dotnet-script\1.2.0\dotnet-script\1.2.0\tools\net5.0\any\Dotnet.Script.Core.dll file misses that instruction:

#if NETCOREAPP3_0_OR_GREATER
using var contextualReflectionScope = assemblyLoadContext != null ? assemblyLoadContext.EnterContextualReflection() : default;
#endif

Have no idea how that could happen, other than a bug in toolchain version installed at the build server.

I will cover this with a unit test and will send a PR.

Maybe just?

!NETSTANDARD2_0

!NETSTANDARD2_0

That line does not need NETCOREAPP3_0_OR_GREATER condition anymore as we dropped netcoreapp2.1.

Not a problem, as it will be covered in a test after implementation of opt-in option. It seems that the build server just has an older or buggy version that does not understand NETCOREAPP3_0_OR_GREATER.

Perfect. Let's hope that solves the issues 👍😊
