Before we begin we want to let you know that you should uninstall any prior ES2008 beta's including the release candidate before installing the official release. The official release is version number 2008.1.0623.0 (yyyy.major.mmdd.minor) and passes all of our regressions tests. We were also able to sneak in fixes and enhancements such as support for the new "rowversion" data type in Microsoft SQL Server CE which providers support for concurrency checking, and other fixes as well. The installer also now installs two versions of our .CHM based help system. We still ship the full blown help system but we also provide a new scaled down "simple" version which you will find on your menu after installing. This simple version should prove very useful if you are just getting started with EntitySpaces.

• Leaving esDataSource.TotalRowCount set to -1 it will cause it to calculate it for you (no need for a second query).
• Better exception handling. All low level database exceptions should bubble up to the application code. No more "Object reference not set" errors.
• The installer also ships full source for the EntitySpaces.MetadataEngine.dll plugins for both Sql Server CE and VistaDB so you can recompile these if you need to use different versions.
• All assemblies have new strong name keys and the source code does not come with the .SNK files, if you need to recompile the source code you will need to generate your own EntitySpaces.snk files.
• Generating code with "Generate Single File" set to false should no longer have any errors.
• Fixed Query.OP() LIKE/NOT LIKE for public use.
• Fixed parameter direction in Oracle delete stored procedures.
• Fixed property settor when INotify and Hierarchical are both checked
  • http://community.entityspaces.net/forums/thread/8951.aspx
• Properties that are not brought back by queries no longer throw exceptions, they simply return null if accessed. This is very nice for our proxies as you no longer have to return all columns for the proxies to work properly.
• Many other minor fixes and enhancements were made.
  

Assemblies

The Standard Assemblies for .NET 2.0 and .NET 3.5

The Compact Framework Assemblies for .NET 2.0 and .NET 3.5

There is a special version of the EntitySpaces.Core.dll in the "Web" subfolder that allows for better binding in ASP.NET scenarios when extra columns are brought back by joins and by other means. This should eliminate the need to use LowLevelBind().

Both our .NET 2.0 and .NET 3.5 EntitySpaces.SqlServerCeProvider.CF.dll's are bound to the 3.5.0.0 version of System.Data.SqlServerCe.dll. If you need to redirect the bindings you can do so, see this post. Both our .NET 3.5 versions of EntitySpaces.SqlClientProvider.dll and EntitySpaces.SqlServerCeProvider.dll (Desktop) have support for LINQ.

From mobile devices to large scale enterprise solutions in need of serious transaction support, EntitySpaces can meet your needs. Whether you’re writing an ASP.NET application with medium trust requirements, a Mono application, or a Windows.Forms application, the EntitySpaces architecture is there for you. EntitySpaces is provider independent, which means that you can run the same binary code against any of the supported databases. EntitySpaces is available in both C# and VB.NET. EntitySpaces uses no reflection, no XML files, and sports a tiny foot print of less than 200k. Pound for pound, EntitySpaces is one tough, dependable .NET architecture.
