I've inherited C# code that has an awful lot of DateTimes where the Kind property is DateTimeKind.Unspecified. These are fed into Datetime.ToUniversalTime() which gives back a UTC datetime (it adds 7 hours in my case). This is how ToUniversalTime() works; see MSDN. The problem is that these DateTimes are in fact already in UTC time. They are pulled out of a SQL Server Compact 4.0 database. They were stored there in UTC. My main question is: How do I modify the Kind property of a DateTime so that it's UTC and not Unspecified? I don't want to change the time or date. So for example, a date of

I'm trying to move my EF6 configuration from myexe.exe.config to code as a workaround for the empty DbProviderFactories node in machine.config -issue (described here: https://stackoverflow.com/a/24273922/600559 ). I don't want to change the machine.config file. I have read the Code-Based Configuration (EF6 onwards) . I have tried implementations like this: https://stackoverflow.com/a/23130602/600559 , however I cannot get it to work. Does anyone have a working EF6/SQL CE/code-based configuration solution? Here's my my changes (from a working .config solution to a code based solution): New

I have a SQL Server CE database that works fine in dev, but when installed on the client has an issue. The SQL Server CE 3.5 dependencies are copied as part of the deployment. The target machine is a clean Windows 7 32-bit Ultimate image. The message for the exception in the event log is: Message: Internal error: Cannot open the shared memory region. Stack Trace: at System.Data.SqlServerCe.SqlCeConnection.ProcessResults(Int32 hr) at System.Data.SqlServerCe.SqlCeConnection.Open(Boolean silent) at System.Data.SqlServerCe.SqlCeConnection.Open() at System.Data.Linq.SqlClient.SqlConnectionManager

Does any one know of an example on how to store an image in a SQL Server CE database? What data type should the column be? (I am guessing binary.) I use Linq-To-Datasets. Is it possible using that to put the image into the database and pull it out again later? Thanks for any advice. Here is how I did it: MemoryStream stream = new MemoryStream(); myBitmapImage.Save(stream, ImageFormat.Png); myInsertLinqToDataSetRow.IMAGE_COLUMN = stream.ToArray(); To load it back out again I did this: MemoryStream stream = new MemoryStream(myLinqToDataSetRow.IMAGE_COLUMN); myBitmapImage.SignatureImage = new

I am trying to write a query that gets table information from a SQL CE database, ready to be put in c#, later to be exported to XML. I need one of the columns to be named 'IDENT' with a boolean value (to represent whether or not it is the identity column, obviously). For this, I am checking if the AUTOINC_SEED column is null, as follows: select isnull(AUTOINC_SEED) as IDENT from information_schema.columns However, this returns TRUE for non-identity columns and FALSE for identity columns! Is there any way to reverse the boolean value inside the select statement? Edit: I'm aware I could do a

How do I deploy SQL CE 4.0 with EF4 to a shared hosting provider for ASP.NET MVC 2.0? I've included System.Data.SqlServerCe.dll, and the amd64 + x86 directories in my bin folder, but keep getting a ".net provider not found". I realize it's currently in CTP, but this is just for testing purposes. My project + host is configured for .net 4.0 Loren Paulsen With Visual Studio 2010 there is now an easy way to deploy SQL CE 4 to a shared hosting environment through the use of "Deployable Dependencies". You do not need to manually copy dlls to your bin folder or modify your web.config. Both of these

Self answering question for future reference: If you have a table where you deleted and re-added content, you can get this error while inserting new rows with an ID equal to existing IDs: Server Error in '/' Application.
