I'm trying to install the recently released WiX Toolset v4 and not having any luck.

According to the docs, "The wix.exe tool requires the .NET SDK, version 6 or later." I installed the .NET SDK 7.0 via winget and ran the command to install WiX only to receive the following errors:

C:\Program Files\dotnet>dotnet.exe tool install --global wix --version 4.0.0

C:\...\restore.csproj : error NU1100: Unable to resolve 'wix (>= 4.0.0)' for 'net7.0'.
C:\...\restore.csproj : error NU1100: Unable to resolve 'wix (>= 4.0.0)' for 'net7.0/any'.
The tool package could not be restored.
Tool 'wix' failed to install. This failure may have been caused by:

* You are attempting to install a preview release and did not use the --version option to specify the version.
* A package by this name was found, but it was not a .NET tool.
* The required NuGet feed cannot be accessed, perhaps because of an Internet connection problem.
* You mistyped the name of the tool.

I removed the .NET SDK v7, installed v6, tried the WiX install again, and got the similar results. Also tried removing the --version to see if it would install any version of the WiX Toolset, but no such luck:

C:\...\restore.csproj : error NU1100: Unable to resolve 'wix (>= 0.0.0)' for 'net6.0'.
C:\...\restore.csproj : error NU1100: Unable to resolve 'wix (>= 0.0.0)' for 'net6.0/any'.

Anyone know what I'm doing wrong or missing here? The statements to install seem fairly straightforward, but the errors (and the accompanying error documentation) aren't much help (to me, anyway).

Does dotnet nuget list source list https://api.nuget.org/v3/index.json? The WiX tool NuGet package is on nuget.org so you have to include the NuGet.org feed in your source list.

You can also run

dotnet tool install --verbosity detailed --global wix --version 4.0.0

to get more detail about the attempt. It includes a list of feeds, too:

    `dotnet nuget list source` lists a whole bunch o' nuthin (i.e. "No sources found."). Ran `dotnet nuget add source "https://api.nuget.org/v3/index.json"`, tried the `tool install` command again and it worked like a charm. Thanks! – John Straffin Apr 26 '23 at 20:24
