I have a very simple VS2019 .csproj file which can be seen below:
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFramework>netcoreapp3.1</TargetFramework>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="AST.NxTestware.main" Version="1.0.0" />
</ItemGroup>
</Project>
When I save the csproj file, I can see in my right hand side the dependency is downloaded, and I can find the installed NuGet package on my PC

Under the manage nuget package window I can see a newer version 1.1.0

I want to edit my .csproj file so that it always installs the most recent NuGet package version, and I tried doing so by setting version="*"
https://docs.microsoft.com/en-us/nuget/concepts/package-versioning
but setting version=* causes my VS2019 dependency list to show a yellow warning circle now which wont go away, and if I check my local NuGet installation folder I can see that nothing got installed
How can I tell VS2019 to automatically install the latest version of my NuGet package?
