Crankier error : A compatible installed .NET Core SDK for global.json version [5.0.100-alpha1-014696] from [global.json] was not found

[Pibe93]

Good evening, I'm trying to run a stress test here in local development (dotnet run -- local --target-url https://localhost:44368/echo --workers 10) to see how it works because then I'll have to run a stress test on the server on which to install my server project with Asp.net core 3 with Signalr to see how many connections I can keep connected but I get this error:
A compatible installed .NET Core SDK for global.json version [5.0.100-alpha1-014696] from [C:\Users\MarcoG\Downloads\AspNetCore-master\global.json] was not found
Install the [5.0.100-alpha1-014696] .NET Core SDK or update [C:\Users\MarcoG\Downloads\AspNetCore-master\global.json] with an installed .NET Core SDK:
2.1.602 [C:\Program Files\dotnet\sdk]
2.1.801 [C:\Program Files\dotnet\sdk]
2.2.300 [C:\Program Files\dotnet\sdk]
3.0.100-preview8-013656 [C:\Program Files\dotnet\sdk]
3.0.100-preview9-014004 [C:\Program Files\dotnet\sdk]
3.0.100 [C:\Program Files\dotnet\sdk].

Thanks for support.

1. You first need to get the SDK for the repo, run "restore.cmd" in the root of the repository
2. Follow the instructions for using dotnet from the command line in the repo https://github.com/aspnet/AspNetCore/blob/master/docs/BuildFromSource.md#using-dotnet-on-command-line-in-this-repo

Thank you so much BrennanConroy.
Now I look good and give feedback as soon as I tried.
Thanks again for availability.

Good evening,
after cloning the project and executing the ./restore.cmd command I have the following error:

C:\Users\MarcoG\source\repos\AspNetCore\eng\tools\RepoTasks\RepoTasks.csproj :  error: Version 5.0.100-alpha1-015536 of the .NET Core SDK requires at least version 16.3.0 of MSBuild. The current available version of MSBuild is 16.0.461.62831. Change the version of the .NET Core SDK specified in global.json to an older one that requires the currently available MSBuild version.
C: Username Marco G o rep netNetCore en tools RepoTasks RepoTasks.csproj: error MSB4236: the SDK 'Microsoft.NET.Sdk' specified was not found.

[BrennanConroy]

You probably need to update Visual Studio to version 16.3.

[Pibe93]

The version I'm using is as follows:
Visual Studio Community 2019 Preview
16.3.0 Preview 3.0

[Pibe93]

I need to use the Visual Studio Community version 16.3.8?

[BrennanConroy]

I'm not sure, it probably doesn't hurt to update.

[Pibe93]

I used visual studio enterprise latest version, the restore was successful but when I go to the Crankier folder and execute the command I always get an error on the SDK version:
A compatible installed .NET Core SDK for global.json version [5.0.100-alpha1-015536] from [C:\Users\MarcoG\source\repos\AspNetCore\global.json] was not found

3.0.100-preview9-014004 [C:\Program Files\dotnet\sdk]
3.0.100 [C:\Program Files\dotnet\sdk]

[BrennanConroy]

restore.cmd will install the appropriate SDK for the repo in a local folder. In order to then use it on the command line as if it was installed globally you need to follow the instructions on using dotnet on the command line

I can't build the repo using buid.ps1 either.

@aspnet/build have any ideas why this error would be seen with VS 16.3 or higher installed?
