Global using list missing using aliased global usings

This issue has been moved from a ticket on Developer Community.

[severity:It's more difficult to complete my work]
Global usings with aliases do not show up in global using list

<ItemGroup>
	<Using Remove="System.Net.Http"/>
	<Using Include="NodaTime" Alias="MyTime"/>
</ItemGroup>

<ItemGroup>
		<PackageReference Include="NodaTime" Version="3.2.0" />
	</ItemGroup>

Save and build. Confirm that your alias is available (attach 1)

Click the glyph. MyTime is missing (attach 2)

I initially thought this was just via the project file, but further experimentation shows it also occurs with aliases in a global using in the project.

I really enjoy how excited folks get in talks when I show them this glyph. However, I also show that they can use aliases in project files, so this bug shows up. Please fix.

It may be simpler to understand this with the following example. (For example, the removal of another global using is irrelevant). This is all in relation to the fantastic feature of showing global usings via a glyph at the top of the file. I believe I did something to turn this on, but cannot find the setting.

There are three problems, in decreasing order of seriousness:

• Adding an alias causes a global using to disappear from the list of global usings
• You need to rebuild several times to get the list to update
• Aliases do not appear

The first, and to a lesser degree the second, make the list appear unreliable.

Start a normal console app and paste this into the .csproj file:

<Project Sdk="Microsoft.NET.Sdk">

	<PropertyGroup>
		<OutputType>Exe</OutputType>
		<TargetFramework>net9.0</TargetFramework>
		<ImplicitUsings>enable</ImplicitUsings>
		<Nullable>enable</Nullable>
	</PropertyGroup>

	<ItemGroup>
		<Using Include="NodaTime"/>
		<Using Include="System.Linq" Alias="LinqStuff"/>
	</ItemGroup>

	<ItemGroup>
		<PackageReference Include="NodaTime" Version="3.2.0" />
	</ItemGroup>

</Project>

Note, that NodaTime does not have an alias.

Clicking the glyph at the top of the file to display global usings (fantastic feature) shows:

Now, add an alias to NodaTime:

		<Using Include="NodaTime" Alias="JonsTime"/>

Rebuild a couple of times. Then the glyph fails to show NodaTime at all:
