So I am trying to create my ADO Entity data model, and i cant seem to get past the "choose your data connection" page. I choose the correct connection, then click either no or yes for sensitive data, and i click next. However, nothing appears. There is no error message like the common "your project references the latest version of entity framework however an entity framework database provider." It just closes the prompt and returns me to my project.
Has anyone ever seen this before?
If you have such a problem, make sure that the version of the NuGet MySQL EF package matches the version of the MySQL Connector for NET

I am using Vb 2010 in designing my apps. I've connected my database with my application but I didn't use any code in the connection. I used Data source and Databinding property and when I save the data the database is always empty. Please help me with a solution.
Place a BindingNavigator component in your form and set it's binding source property to the same datasource of your other component.
I inherited a legacy system using Crystal Reports in VS.NET pulling info from an Oracle11g DB.
The database fields are in "REPORT_DATA", I updated the stored procedure which the code is querying to add a field, however I cannot see that new field in the field explorer.
When I click on "Verify Database" and manage to log into the DB I get a "Remove Table" prompt - "The database table "REPORT_DATA" cannot be found. Proceed to remove this table from the report?"
Of course, there is no REPORT_DATA table and there never was.
When I preview the report or put it on the server it works, so there is some behind-the-scenes magic which I don't understand.
Figured it out.
I had to highlight the server name in the “Current Data Source” area and the name of the server in the “Replace With” area on the Set Datasource Location window. Then click the “Update” button.
Since the report wasn't built on my machine it had to be reconfigured - can't figure out why it still connected to the DB when previewing though.
I am using linqpad4 with it's CRM 2011 plugin.
I get this error. How to fix it.
Does not contain a definition...and no extension method...
This error means something is changed in CRM schema, customization is published and you're trying to use new attribute in query but LinqPad schema is not updated.
Select the connection from left navigation, Right click and select Connection Properties. Ont he dialog bottom left Click on Refresh Schema. This will update the schema. Now you can work with latest schema.
I have an issue and I cannot find out what the problem is. In visual studio 2010 I'm trying to add a new ADO.NET entity data model through the wizard (I'm using Entity Framework 4.1). After the second wizard step (that says "Choose your Data Connection") I press next and the wizard is closed right away, and there are no following steps at all. Here is my entity connection string:
metadata=res://*/DAL.Model1.csdl|res://*/DAL.Model1.ssdl|res://*/DAL.Model1.msl;provider=System.Data.SqlClient;provider connection string="Data Source=DMITRIY-TOSH\SQLEXPRESS;AttachDbFilename=|DataDirectory|\ASPNETDB.MDF;Integrated Security=True"
Is there anything wrong with that connection string? What should I change in it and how? Or what else can be the cause of the problem? Help me with this, please. I don't even know how to make it work to see the next wizard step where I can choose tables.
Found the solution. The folder "App_Data" (with the database inside) wasn't included into the project. Only because of that the wizard did not work.
I had this problem too, all the above didn't work for me. What helped for me was the following.
When you try to connect with a database that database can have different users with different credentials it can accept. Let's say user A till D.
If you try to connect with a user make sure that user has the right credentials enabled, in this case, read and write options enabled.
To do this start MS SQL Server Managment Studio, connected with your SQL server and select the database you try to make a connection with in visual studio. Under 'your_dbname' --> Security --> Users you find a list of users. Rightclick the username you try to login with and select properties. A window opens. Select the 'General' (selected by default) page and under tab 'Database role membership' make sure 'db_datareader' and 'db_datawrite' are selected.
Note: When you log in too MS SQL Server Managment Studio make sure you log in with a user which can enable/disable these options...
I created an empty model, then selected it in 'Model browser', right clicked on it and selected 'Update model from database'. Then I was able to add a table to it...
I have a data source that I use for creating reports in my programme. I've recently changed the connection string to the table adapters created by the wizard(ConString1), because I wanted to make that connection string available to every other class that needs to use it. So basically. I deleted the application setting created by the wizard(ConString1) and entered in my own application setting(ConString). Once debugging began all the code that still refered to the now non existent connection string(ConString1), I changed to the available one(ConString). That is in the code the debugger picked up. The program works fine.
Now my problem is this, when I select a table adapter and take a look at its properties, the Connection string is still set to the old connection string name, the connection string value itself is given as "Unable to find connection ". This is prohibiting me from adding new tables to my reports.xsd file.
I also keep getting an error when trying to create a new datasource.
Error : Could not load type Microsoft.VisualStudio.DataDesign.SyncDesigner.SyncFacade.SyncManager.
Right-click on the data-set xsd, select "Open With..."

Modify as needed, and be careful.
Be careful.
