Versions and references for frequently changing projects

[fatagun]

What are the differences between

<ItemGroup>
	<PackageReference Include="SomePackage" />
</ItemGroup>

and

<ItemGroup>
	<PackageReference Include="SomePackage" Version="4.0.0" />
</ItemGroup>

and

<ItemGroup>
	<PackageReference Include="SomePackage" Version="4.0.0-*" />
</ItemGroup>

?

Similarly,

<FrameworkReference Include="Microsoft.AspNetCore.App" />

and

In an environment where package versions change very often, what is the strategy to reduce changes in projects?

Can you please elaborate?

Thanks.

This is a better discussion for either NuGet/Home, or dotnet/sdk.
