Problems with Schema XML attribute in EDMX file

Question

I am using a T4 template that generates POCOs from EDMX files.

All underlying entities have their own schemas. That answer describes how you can extract the schema name from an EDMX:

StoreItemCollection sic;
loader.TryCreateStoreItemCollection(inputFile, out sic);
EntityContainer sicEntityContainer = sic.GetItems<EntityContainer>().First();

EntitySet eset = sicEntityContainer.GetEntitySetByName(code.Escape(entity), true);
string schemaName = eset.MetadataProperties["Schema"].Value.ToString();

If I look at the content of an EDMX file, I find out that there is a Schema attribute for each entity:

<EntitySet Name="Table_1"
           EntityType="TestModel.Store.Table_1"
           store:Type="Tables"
           Schema="Blubb" />

At this point anything works fine and I can extract the schema name.

AND HERE IS THE PROBLEM:

Since one or two month Visual Studio 2010 adds a prefix called store to the Schema attribute of newer Entities in my model.

<EntitySet Name="Table_1"
           EntityType="TestModel.Store.Table_1"
           store:Type="Tables"
           store:Schema="Blubb" />

So I cannot extract the schema by using the logic of the upper linked article.

I have to remove these prefixes with a text editor manually, so anything can be worked fine.

My questions:

1. What is the reason for that?
2. How can I read-out attributes with namespaces like store:Schema?

Answer 1

You need to prefix the "Type/Schema" with its namespace

ie:

 eset.MetadataProperties["http://schemas.microsoft.com/ado/2007/12/edm/EntityStoreSchemaGenerator:Type"].Value.ToString(); 
 eset.MetadataProperties["http://schemas.microsoft.com/ado/2007/12/edm/EntityStoreSchemaGenerator:Schema"].Value.ToString();
