Blazor app template fails when name with hyphens used

[timheuer]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

When you create a new Blazor app using the template with a name like name-with-hyphens it will fail in later stages due to some failed replacements in the template, namely default namespace

Expected Behavior

sourceName gets replaced appropriately with safe values where they are used

Steps To Reproduce

1. File ... New Project ... Blazor (choose interactive render mode = Wasm)
2. Choose name something-with-hyphens
3. Add a class via Item template
4. Compile

EXPECT: compile
ACTUAL: Fail because the class template brings in namespace and uses default namespace which in the csproj files still includes the hyphen in the name
