Very slow "dotnet restore" in 9.0.200 or higher version

[tresoldigiorgio]

The "restore" command is very slow in version 9.0.200 or higher.

I've created a simple project with only one dependency to my other nuget package and launched
dotnet restore --interactive --force --no-cache

in 9.0.101 or 102 the command is very fast (2 seconds) but in 9.0.200 or 202 (1:41 minute) is extremely slow and cunsumes large amount of ram (8GB).

this is my csproj

`

<PropertyGroup>
    <TargetFramework>net9.0</TargetFramework>
</PropertyGroup>

<ItemGroup>
    <PackageReference Include="Nuvyta.SDK.App.Manager" Version="4.3.*" />
</ItemGroup>

`

this is the log by versions

101.log
102.log
200.log
202.log

this is my project dependencies

@aortiz-msft @nkolev92 Since this is restore, I have to assume it's nuget related. Should we have them open an issue there?

[nkolev92]

Yes.

I'm guessing it's the same root cause as NuGet/Home#14147, which is awaiting release in April.

@tresoldigiorgio Do you have latest Visual Studio? Can you try 17.13's latest VS version?
Run msbuild /t:restore and it's the same as dotnet restore except it'll use the toolset that ships with VS.

It should have the fix.

I don't use Visual Studio but Rider.
The big problem is azure devops builder for me

I will follow nuget issue for resolution. Thanks!
