It's working fine for me with the following commands:

dotnet tool restore
dotnet restore
dotnet async-generator

BTW, I've opened another PR #57, maybe you could take a look at it before doing the release.

dotnet async-generator in my env =>

AsyncGenerator.CommandLine[0]
Visual Studio installation directory was not found. Install Visual Studio or set the environment variable VSINSTALLDIR
System.InvalidOperationException: Visual Studio installation directory was not found. Install Visual Studio or set the environment variable VSINSTALLDIR
at AsyncGenerator.Internal.EnvironmentHelper.Setup() in C:\Workspace\Git\AsyncGenerator\Source\AsyncGenerator\Internal\EnvironmentHelper.cs:line 120
at AsyncGenerator.CommandLine.Program.Main(String[] args) in C:\Workspace\Git\AsyncGenerator\Source\AsyncGenerator.CommandLine\Program.cs:line 39

This happen even in dev command prompt where %VSINSTALLDIR% defiantly is available.
What has changed since I last created a release is that im on a fresh computer environment. VS2022 only (+rider).
Any clue? thanks.

...after merging #57 it works fine for me it seems. Some fix in upgraded async-generator probably did the trick!
