Starting with .NET 9 I have a Solution containing a Blazor webapp, a couple of .NET 9 class libraries and ONE class library in .NET Standard 2.0 with only 2 entities.
When I run the Blazor project with dotnet watch, I get a warning coming from the .NET Standard library:
dotnet watch ⚠ msbuild: [Warning] Found project reference without a matching metadata reference: D:\DEV\Microgate\Microgate.Projects\src\Microgate.Projects.Contracts\Microgate.Projects.Contracts.csproj
The .csproj is very simple:
<Project Sdk="Microsoft.NET.Sdk"><PropertyGroup><TargetFramework>netstandard2.0</TargetFramework><Nullable>disable</Nullable></PropertyGroup></Project>And it has NO references at all:
Any advice on how to remove the annoying warning? Before upgrading to .NET 9, I didn't have this...
