Hi Daniel Silva, I have already check that solution, but it didn't work, a windows appears with the next message: 'SQL CE Core was not properly installed" and a console windows: failed to add assembbly : "system.data.sqlserverce.dll" also when I run the application another windows appear:
faulting module: sqlcese35.dll
NativeMethods.CreateDatabase(IntPtrpOpenInfo, IntPtr$ pError)
Also I have another question, Im not an .Net programmer I know a few things here and there, so I not sure about this, rigth now I have my develop enviroment only for the mk3000 with a visual studio 2008 and EMDK for .net v2.8 , if I install the correct dependecies to develop on Windows Embedded Compact 7, will I still be able to develop applications fow win ce 6.0 or 5.0? I ask because a year ago I did this and have trouble to make some apps work with these Win CE versions I have to reinstall everything again.
