CSharpRepl doesn't work on .NET 6 Preview ("Version string portion was too short or too long") #8

PathogenDavid · 2021-06-04T14:14:18Z

Hello!

When I start CSharpRepl I'm presented with this error:

One or more errors occurred. (Version string portion was too short or too long. (Parameter 'input'))

Attempting to type any character results in this exception:

> Unhandled exception. System.NullReferenceException: Object reference not set to an instance of an object.

However, it works fine on my laptop. A noteworthy difference between the two machines is that my desktop has .NET 6 Preview 4 installed while my laptop does not. Based on the error I'm assuming that's the culprit (something choking on the pre-release suffix?), but I did not have a chance to dig very far so that might be a red herring.

The text was updated successfully, but these errors were encountered:

Interesting, thanks for reporting! I also have .NET 6 Preview 4, and csharprepl is working, but I think you're right that .NET 6 probably has something to do with it. Could you please run dotnet --info and paste the results here? Thanks!

waf · 2021-06-04T14:41:56Z

Ah, I managed to recreate this by setting the TargetFramework to net6.0 -- I'll work on a fix.

Thanks a lot for looking into it! Here's my dotnet --info just in case you end up needing it anyway:

To install additional .NET runtimes or SDKs:

When we're determining the shared framework implementation paths, we parse the version number to a `System.Diagnostics.CodeAnalysis.Version` so we can choose the latest point release (so e.g. 5.0.10 comes after 5.0.9, which wouldn't be the case for normal string sorting). However, for preview versions of .NET, the version string has a trailing identifier, e.g. `6.0.0-preview.4.21253.7`, which causes `System.Diagnostics.CodeAnalysis.Version` to throw. Note, unit tests were failing when targeting `net6.0`; this fixes them all. fixes #8

This fix shipped in version 0.2.2, thanks! You can update via:

dotnet tool update -g csharprepl

It may take a bit of time before the package is available globally via NuGet.org.

Thanks for the quick fix, works great! Looking forward to trying this out, I've been wishing for a good C# repl experience outside of Visual Studio for quite some time.
