try-convert crashes with "Could not load file or assembly 'System.Runtime"

[MattBussing]

When running try-convert I get these weird issues.

try-convert.exe --no-backup -m /c/Program\ Files/dotnet/sdk/6.0.300/ --keep-current-tfms -p normalProject.csproj
System.IO.FileNotFoundException: Could not load file or assembly 'System.Runtime, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.

dotnet tool update -g try-convert
Tool 'try-convert' was reinstalled with the latest stable version (version '0.9.232202')

[MattBussing]

It works if I build the latest of try-convert. Please update the NuGet package.

[DingpingZhang]

Me too, it doesn't seem to have a stable version.

[luizfernandonb]

Me too

[ShoshanaTzi]

Me too

I caught the same error too.

I am seeing the same issue

try-convert -m "C:\Program Files\dotnet\sdk\7.0.101"

and, me too (with multiple SDK 6 versions installed)

Looks like this utility is essentially abandoned. Would be nice if this page https://learn.microsoft.com/en-us/dotnet/core/porting/ stopped pointing people at it?

Same error reported many more times at issues below (duplicates of this ticket). https://github.com/dotnet/try-convert/issues/463 https://github.com/dotnet/try-convert/issues/445

Perhaps this is the replacement? https://learn.microsoft.com/en-us/dotnet/core/porting/upgrade-assistant-overview

Any update with the new tool AKA the replacement?
