Package coveralls.net 3.0.0 is not compatible with net5.0 (.NETCoreApp,Version=v5.0)

[MarcosCostaDev]

I am receiving some errors during the installation process using Nuget Package Manager on Visual Studio 2019.

Invalid project-package combination for coveralls.net 3.0.0. DotnetToolReference project style can only contain references of the DotnetTool type

Follow by

Package 'coveralls.net 3.0.0' has a package type 'DotnetTool' that is not supported by project

And

Package coveralls.net 3.0.0 is not compatible with net5.0 (.NETCoreApp,Version=v5.0). Package coveralls.net 3.0.0 supports: net5.0 (.NETCoreApp,Version=v5.0) / any

this is my test project

I believe this is correct...
dotnet/sdk#9122
This new type of tool needs to be installed with dotnet tool rather than the older legacy 2.1 tools approach of using PackageReference in a csproj file.
This was a breaking change around the release of version 3.0.0 (and now version 4.0.0 as well)

https://docs.microsoft.com/en-us/dotnet/core/tools/global-tools#install-a-local-tool
Installing of coveralls.net now follows dotnet tool install coveralls.net adding it to the dotnet-tools.json file or dotnet tool install --global coveralls.net to install it globally instead.

As far as I am aware, this kind of tool install is not supported in the Visual Studio Nuget Package Manager.

I've added notes to the readme about this difference in version 3.0.0 and version 2.0.0 already which has a bit more detail.

I hope this helps.
