[.NET 8.0] Conflict

[cocoon]

Hi there,

I just discovered a conflict with the current .NET 8.0 preview 6.

Recently IPNetwork was added to System.Net here:
dotnet/runtime#82779

Error

Program.cs(3,10): error CS0433: The type 'IPNetwork' exists in both 'System.Net.IPNetwork, Version=2.6.598.0, Culture=neutral, PublicKeyToken=717343cc2c25edcf' and 'System.Net.Primitives, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' [...\test.csproj]

The build failed. Fix the build errors and run again.

Program.cs(3,10): error CS0433: Der Typ "IPNetwork" ist in "System.Net.IPNetwork, Version=2.6.598.0, Culture=neutral, PublicKeyToken=717343cc2c25edcf" und "System.Net.Primitives, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" vorhanden. [...\test.csproj]

Steps to reproduce

• Install .NET 8.0 Prev 6 SDK (x64): [Download]
• Start a terminal:

mkdir test
cd test
dotnet new console
dotnet add package IPNetwork2
echo var ip = System.Net.IPNetwork.Parse(""); >> Program.cs
rem VERIFY that TargetFramework is net8.0
more test.csproj
dotnet run

Story

Because of another existing problem (that has nothing to do with IPNetwork), to be able to start processes without windows, I needed to switch to .NET 8 and triggered the conflict.

My current workaround is to rename this IPNetwork class to IPNetwork2.

just for completeness, the other unrelated problem:

dotnet/runtime#68259

UseShellExecute = false

• StartInfo.CreateNoWindow = false
• StartInfo.WindowStyle = ProcessWindowStyle.Hidden
• redirect output

the fix:
microsoft/playwright-dotnet#2623

I noticed this as well, it's not a deal breaker for me since I'm not doing anything in .net8 (still preview yes?) but it did look like perhaps several of the namespaces/types are there.

	<PackageReference Include="IPNetwork2" Version="2.6.609" >
		<Aliases>IPNetwork2</Aliases>
	</PackageReference>

extern alias IPNetwork2;

IPNetwork2.System.Net.IPNetwork

Just ran into this as well. Why is this library, which is not part of the BCL, adding types to the System namespace? That's just asking for issues like this.

Isn't it great, that the source is available and everybody just can change it easily?

This needs to be fixed now that .net 8 is GA.

The fix is on the way! #298
