I'm getting the following weird error when trying to update a SQL CE Db using ORM.
The metadata for field 'name' of Class 'Blah" cannot be initialized: Type converter initialization failed. The convertoer with name SqlCeStringConverter does not convert from CLR type System.Int32 to SQL type nvarchar. Version=2010.3.1125.1
I find this confusing as the name field is string??
Also can anyone direct me on how to map money fields in ORM. I've an existing class that uses doubles.

Hi Michael,
I tried to reproduce your problem, but had no luck. Can you give me your persistent classes project so that I can debug here?
System.Double is mapped by default to the sql ce type 'float'. The range should match and i cannot see problems there.
Kind regards,

I'llk try to replicate it...I managed to get it to do it 3 timnes prior. Ive now deleted the rLinq file a third time and created the tables manually which worked.
There was some issue in a money datatype from sql CE i think??
i should be able to replicate what i did...just need time

Hi Michael,
Please take your time, I tried some combinations but it worked fine so far.

OK more weird behaviour.
The EntityDiagrams.cs file had NO code in it?
I deleted the rlinq & the connection strings in app config...
however the generated classes didnt appear in my project and its added an extra connection string to the app config?
and it's back to none of the inheritance working...what can i send?

OK i broke it again
Here's the scenario:
Created a table with3 fields
ID
PoderID :int
CapsuleID :int
Capacity:Decimal
(it seems decimal is the culprit)
I then R-click on the entity & select "create Table..."
and everything maps except the decimal property which comes up blank & when i mouse over it ...
DATAGRIDVIEW Default Error Dialog
The following exception occured in the DataGridView:
System.ArgumentException: DataGridViewComboBoxCell value is not valid

Hi Michael,
1. It seems that there are problems related to the code generation. The cause for the wrong behavior could be invalid Meta model stored within the rlinq file. I should ask you to provide us a with a sample application which demonstrates that error.
2. In the Table Editor, the SQL types combo box is bound to a collection of database specific types. The Numeric and Decimal SQLCe data types are not part of this collection which leads to the error. This is a known issue which is already fixed and will be part of the product in the next internal build.
3. Could you please share some more details regarding the classes in the project and steps to reproduce the wrong behavior which forces the Visual Studio instance to crash?
I am looking forward to hearing from you.
Best wishes,
