entity-framework-5

I was using EF4 and a piece of code I found to get the MaxLength value from an entity like this: public static int? GetMaxLength(string entityTypeName, string columnName) { int? result = null; using (fooEntities context = new fooEntities()) { Type entType = Type.GetType(entityTypeName); var q = from meta in context.MetadataWorkspace.GetItems(DataSpace.CSpace) .Where(m => m.BuiltInTypeKind == BuiltInTypeKind.EntityType) from p in (meta as EntityType).Properties .Where(p => p.Name == columnName && p.TypeUsage.EdmType.Name == "String") select p; var queryResult = q.Where(p => { bool match = p

If I'm using EF 5 and Database first to generate a .edmx model of my database, how do I get a list of an entity's columns? using (var db = new ProjectNameContext()) { // string[] colNames = db.Users. } What I'm looking for is colNames[0] == "Id", colNames[1] == "FirstName", etc. How about: var names = typeof(User).GetProperties() .Select(property => property.Name) .ToArray(); Of course, this can be used for any type, not just an EF table. var res = typeof(TableName).GetProperties() .Select(property => property.Name) .ToArray(); OR var res = dbContext.Model.FindEntityType(typeof(TableName))

Now, when I right-click on the edmx diagram, EF responds with the message: Value does not fall within the expected range. When I compile the EF project it responds with these messages: Loading the include file 'EF.Utility.CS.ttinclude' returned a null or
