Compiled Models: Entity Type Namespaces

[jamezamm]

I have a scenario where two entity types are named the same but under different namespaces: Schema.UnitMove & SchemaLite.UnitMove.

Even tough in the compiled model, the class name of the compiled entity type is resolved to UnitMoveEntityType & UnitMove0EntityType, the project still gives me compile time errors as the reference to the classes do not include the namespace.

Actual result - Without type qualifier
var gkey = runtimeEntityType.AddProperty(
"Gkey",
typeof(long),
propertyInfo: typeof(UnitMove).GetProperty("Gkey", BindingFlags.Public | BindingFlags.Instance | BindingFlags.DeclaredOnly),
fieldInfo: typeof(UnitMove).GetField("<Gkey>k__BackingField", BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.DeclaredOnly),
valueGenerated: ValueGenerated.OnAdd,
afterSaveBehavior: PropertySaveBehavior.Throw);

Expected result - With type qualifier:
var gkey = runtimeEntityType.AddProperty(
"Gkey",
typeof(long),
propertyInfo: typeof(Schema.UnitMove).GetProperty("Gkey", BindingFlags.Public | BindingFlags.Instance | BindingFlags.DeclaredOnly),
fieldInfo: typeof(Schema.UnitMove).GetField("<Gkey>k__BackingField", BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.DeclaredOnly),
valueGenerated: ValueGenerated.OnAdd,
afterSaveBehavior: PropertySaveBehavior.Throw);

Likely covered by #27203

Setting aside the mentioned workaround, is this issue planned to be properly resolved?

[jamezamm]

The workaround mentioned here no longer works since CSharpHelper is an internal API, thus cannot be accessed.

CSharpHelper has always been a "public internal" API; that means it's public and you can use it, but it's defined in an Internal namespace. This means that it may change across releases, but if you're OK with that there shouldn't be any problem using that.

Note that we have an analyzer that reports a warning when you do this, to prevent accidental usage. But you can suppress that warning.

The below still gives a compile time error "The type or namespace 'CSharpHelper' does not exist in the namespace 'Microsoft.EntityFrameworkCore.Design.Internal'". What am I doing wrong? CSharpHelper Github

#pragma warning disable EF1001 // Internal EF Core API usage.
internal class CSharpHelperWithQualifiedNames : Microsoft.EntityFrameworkCore.Design.Internal.CSharpHelper
#pragma warning restore EF1001 // Internal EF Core API usage.

@jamezamm Make sure to fully reference the Design package, without excluding any assets. For example:

<PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="7.0.5" />

@ajcvickers Thanks it worked.

Does this workaround affect anything else, apart compiled models?

[ajcvickers]

@jamezamm Possibly. Let us know if it changes either migrations or scaffolding for you.
