How to run blazor wasm in jetbrains rider

Question

I am using latest MacOS and latest version of Rider. Seeking advise on how to set up build configuration for a hosted blazor wasm project. Created with this command:

dotnet new blazorwasm --hosted -o blazorhosted

I cd into blazorhosted/server and execute

dotnet run watch

and everything works as expected. But I don't know how to run it in Rider. As a side not also works in VS Code with debugging on client and server.

This is the error I am getting when running the server configuration in Rider

    Microsoft.NET.Sdk.Razor.StaticWebAssets.targets(184, 5): Duplicate base  paths '/' 
    for content root paths '/Users/mha/projects/blazorhosted/Client/bin/Debug/netstandard2.1/wwwroot/' 
    and '/Users/mha/projects/blazorhosted/Client/wwwroot/'.
