dotnet tool install fails

I get error when installing dotnet tool and seem related to long path(not sure if it’s related to https://github.com/dotnet/sdk/issues/10708)

You can invoke the tool using the following command: coverlet
Tool 'coverlet.console' (version '1.7.2-preview-0001-g96f4e91319') was successfully installed.

As you can see if I make path shorter it works. I’m ok with that, but error is a bit hidden and if I search around I found that code related to windows update, so it’s not clear the workaround.

@radical I believe https://github.com/dotnet/arcade/pull/8160 should fix the problem.

We ran into this as well and the culprit seems to be that the standard global tool installation uses very long paths to store the tools

C:\Users\{user}\.dotnet\tools\.store\{PackageId}\{version}\{PackageId}\{version}\tools\{tfm}\any

so should you use a longer package id in your package because the package ID is stored twice you are quite likely to run into long path issues which causes this problem. The only way to install a tool is by not using the global flag but set the tool path to a shorter root path
