Having successfully tried out nHibernate, I would now like to try using Fluent for mapping. My main project is in vb.net but I would really like to use c# for the mappings since the lambda expression capability makes it much cleaner. Can you have a separate project/assembly for your mapping files without creating a circular dependency with domain objects?

View 1 RepliesI would like to ask if you can use VB.NET for NHibernate and Fluent Nhibernate?I have searched the web, but I can't seem to get a detailed or explicit statement that tells that one can use VB.NET for NHibernate and with Fluent.
Many of the samples in the NHibernate site are made in C#. That's why I was wondering if I can't use VB.NET when using NHibernate.
I'm working on a project to replace ADO.NET data access logic using NHibernate where we're not able to map the entire domain model at once. This means we'll have domain classes with property mappings to other domain classes that aren't yet mapped with NHibernate.
Consider a Person class with an Address property (Address being a domain object without an NH mapping and Person being the class I'm mapping). How can I include Address in the Person mapping without creating an entire mapping for Address? Is it possible to call legacy (ADO.NET) data access logic from a custom PropertyAccessor? If so, is it reasonable?
*I asked this within another question here but didn't get a response. I'm hoping to get one in a more concise question.
I am having some redundant primary key issues.I have an Item which contains many reports. I have mapped them as shown below. I can do Session.QueryOver(Of Item).List and there are no extra columns generated. I can also do Session.QueryOver(Of Report).List and there are no extra columns generated.
However, once I try to traverse the relationship from Item to Reports, I get the SQL query shown below. Can anyone tell me why?
[Code]...
Basically I want to be able to do this:
session.ExecuteSql("...");
I don't need it to map to any entities or return any values.
Because there is so little information about VB.Net and (Fluent) NHibernate to be found, I decided to write this question to all other developers finding themselves looking for more information.On of the things i had to struggle with was how to Ignore properties in NHibernate.The reason i had to ignore properties was because we used a Webserivce which cannot serialize Interface classes (ILists). Which are used a lot with NHibernate.
View 1 RepliesI've been using c# for the past year and I enjoy the power you get with Fluent NHibernate. One question that I get from friends is "nice but how can vb.net programmers use this?"So for example- the below is a c# mapping class. How would someone do this with vb.net?
public class PostMap : ClassMap<post>
{
public PostMap()
{
Table("Posts");

I am using Fluent NHibernate to map an Oracle database. It is a legacy database so I cant really change everything I want.There is a GUID field, but the keys are still composite (I will change this as soon as I can so that the keys are not composite, but I cant do it right now). The GUID is a VARCHAR2 field with this layout: 551608b1-275d-49f6-9561-44d01aacf23f. The GUID is not added by a sequence in Oracle, but inserted from code (C# or VB.net)[code]Is the problem that I dont use a sequence to generate my GUID? How can I overcome this?
View 1 RepliesI am using Fluent NHibernate to map out an existing database. For this reason - automapping isn't an option for me.How do I tell NHibernate not to map certain properties? Many of them are read-only, and the others do not need to be persisted for other reasons.
I am writing this in VB.Net.I get the typical error message:"The following types may not be used as proxies should be 'public/protected virtual' or 'protected internal virtual'"I have purposely not made my objects Overridable (equivalent to virtual in C#) because I do not want NHibernate to touch them.
The tables described herein both utilize composite keys. I have a parent table that stores eligibility information per "case". The child table stores eligibility information regarding each individual associated with the case. The child records are differentiated by pin number to make them unique in the child table only.
I am using NHibernate v3.1 with Fluent NHibernate v1.2, both acquired via NuGet packages. The entities are mapped in using the Fluent NHibernate auto-mapper functionality. Any custom mapping is done in the mapping override method for each entity.
Another thing to know is that these tables do not have a "primary key" defined in DB2. They only have "unique keys", which are what you see in the composite key definition below (see code).
T0026_AG_ELIG is the name of the parent table and the corresponding POCO class.
T0265_AG_IN_ELIG is the name of the child table and the corresponding POCO class.
Problem:
The problem is that when I execute the query, all the data is queried, the parent record is successfully mapped to the class, but the returned child rows do not map into the collection on the parent class. NHibernate does generate the queries for the parent and child data. When I execute my own query against the database, the correct data for the conditions does come back. For some reason, the child records are just not being bound to the property on the parent (T0026) class.
Question:
What do I need to do to get the multiple rows coming back from T0265_AG_IN_ELIG to map to their corresponding class and load properly into the specified collection property on the parent class (T0026_AG_ELIG)?
Collection Property of Parent (T0026_AG_ELIG):
Public Overridable Property IndividualEligibilityRecords As IList(Of T0265_AG_IN_ELIG)
Mapping Override for Parent (T0026_AG_ELIG):
mapping.CompositeId() _

View 5 RepliesFor reasons that are beyond my control, I have three Projects. Projects A and B reference project C. Project A references project B so that it can open a large form in project B. I now need to open that large form from project C, but VB won't allow me to add a reference from C to B because that would create a circular dependency. I found a way around it, though. I created a Timer in A, and when I opened C from A, I passed in that timer. When the user performs a certain action, I enable the Timer from A, and this causes C to open B for me.

View 5 RepliesI made a change to a project and hve induced a major problem. I have warnings and errors now, but I can still debug the project with the "last successful build" Iwould like to just revert everything to that build but I can't find a way to eliminate the problems I induced or find a way to go to a earlier build. Hopefully I can get back to an earlier version or I will loose the entire project as I can no longer get to the designer.
View 5 RepliesIf I put this piece of code in a new fresh vb.net form, add a button and two labels and start debug I get execution time of about 11.5s.If I put the same piece of code in a new form in an old project upgraded from an earlier version of vb.net, start debug I get an execution time of 7.5s.So I do exactly the same in the two projects but get different execution times.
What do I have to do with the fresh new project to get the same execution time ?I am not interested in improving the code to be able to calculate primes faster. I just want to know what is the significant difference between an old upgraded project and a new fresh one. I am using windows 7 64bit on a 2,4 Ghz Intel quadcore.

I'm developing application that is plugable. The plugins are loaded via Assembly.LoadFrom(). In my solution I have 4 projects. A WPF, 2 DLL and another DLL that is a plugin for the app. The plugin project references one of the other DLLs. When I build the Solution and run I was getting an error trying to use the plugin dll because it was expecting an older version of the referenced project. I had to clean and rebuild the plugin project to get it to run correctly.

I am developing a Multi-Project solution (A, B) in Visual Studio 2008.
I need to run a second project from the start up one and then the first project should be closed.
The matter is that I want to Exit the A.exe and kill the process and the dll that are depending on it. And then Run the B.exe.
I am using 8 different vb projects in one solution, beside this I am also using one 3rd party control ion all the projects, while compiling the application it takes around 5 minutes to build the project, While building the application I have observe that it uses lc.exe file which is used for "Reads text files that contain licensing information and produces a .licenses file that can be embedded in a common language run time executable." at this point it takes too much time.

I createdindows Form application, built it and deployed it with no problems.
