Describe The Bug

Hi,

We have been setting up template solution with multiple projects.
The approach is that we’re using a template.json config file in the C# Solution.

When we creating a new solution with the template and set the name with uppercase characters
for example: “MyNewSolution”.

An new Solution will be created but all the replacements contains lowercase characters “mynewsolution”, all the uppercase characters are gone.

When we don’t use the option “EditorTreatAs”: “solution” then we get the all the replacements with upper en lowercase characters

To Reproduce

Steps:

1. Create a new tamplate json
   { "$schema": "http://json.schemastore.org/template", "sln": { "slnFileName": "placeholder_projectname.API.sln" }, "author": "Company", "classifications": [ "WebAPI", "Team X" ], "name": "Team.X.WebAPI.Template", "identity": "Team.X.WebAPI.Template", "shortName": "teamxwebapi", "tags": { "language": "C#", "type": "solution", "editorTreatAs": "solution" }, "sourceName": "placeholder_projectname", "preferNameDirectory": true }
2. Import new template
3. Create new project/solution with the new template and set the name with upper and lowercase characters
4. Project/solution is created and shows lowercase namings

Triage details

Summary: EditorTreatAs 'solution' in template.json causes name replacements to be lowercased

Reasoning: This is a user-reported issue with no community signal (0 upvotes, 0 comments), no labels, and no maintainer engagement since November 2023 — over 2.5 years ago. The report describes behavior with 'editorTreatAs: solution' causing lowercase name replacements, but it's unclear whether this is a VS-specific issue or a template engine bug, and no maintainer has investigated. The lack of any activity suggests this was not prioritized.
