https://github.com/weltkante/managed-lzma/commit/3e12204c60ada8164561a841bb8dcb4c96078c99



The upgrading the project "master" to .Net8 with the `upgrade-assistant` tool, and finally building in release mode with "dotnet build master.2012.csproj /p:Configuration=Release"



This is a workaround from an earlier version of the project, and the support should either use the published `0.2.0-alpha-7` version from NuGet, or perhaps be deprecated.



Full instructions for building:

```

git clone https://github.com/weltkante/managed-lzma

cd managed-lzma

git checkout 3e12204c60ada8164561a841bb8dcb4c96078c99

upgrade-assistant upgrade master/master.2012.csproj --operation Inplace --targetFramework net8.0

cd master

dotnet build /p:Configuration=Release master.2012.csproj

```



Result file is in `bin/Release/net8.0/managed-lzma.dll`
