I want to connect the Firebird database with Entity Framework Model. Completed the successful installation and created the database. But, I am facing the issue 'Index was outside the bounds of the array' while connecting the database. Refer the below image.
Visual Studio 2015
Firebird client version 4.10.0.0
DDEX Provider version 3.0.2.0
Firebird setup v3.0.4
I followed the steps as suggested in this link. But I choose 'Embedded Server' as server type. https://firebirdsql.org/file/documentation/reference_manuals/fbdevgd-en/html/fbdg30-efw-vs-prepare.html
After done the above configurations, I faced the below.
Unable to load dll 'fbembed': The specified module could not be found. (Exception from HRESULT:0x8007007E)
So, I set 'fbclient.dll' as a client library in the advanced option. After that I am facing this error
Index was outside the bounds of the array
What I have done wrong here? Please correct me.

I am trying to build a basic web app, and I want to connect it to a database. I have a heroku account so I started trying to get it hooked up to a Postgres DB and ran into issues around SSL and external connections. I tried to update my code and realized that I was missing the references to SQL so tried adding Entity Framework through the package manager.
It goes through the checking compatibility and then tells me
Could not add Entity Framework
I am new to this so not sure what I can provide to help get the answer.
Am I just going about it wrong, is EF not what I need to make a simple DB connection?
I tried to configure a project in MonoDevelop on Ubuntu, to use EntityFramework with Npgsql provider, by following official steps.
However, something seem to be wrong with that suggested configuration file (or I'm missing something), as I can't get rid of this error:
The Entity Framework provider type 'Npgsql.NpgsqlServices, Npgsql.EntityFrameworkLegacy, Version=2.1.0.0, Culture=neutral, PublicKeyToken=5d8b90d52f46fda7' registered in the application config file for the ADO.NET provider with invariant name 'Npgsql' could not be loaded. Make sure that the assembly-qualified name is used and that the assembly is available to the running application. See http://go.microsoft.com/fwlink/?LinkId=260882 for more information.
Does anyone have a simple working example of the application connecting to PostgreSQL using Entity Framework in MonoDevelop?
Please try with Npgsql 3.0.3 (the error says 2.1.0), the correct package for this would be EntityFramework6.Npgsql, not Npgsql.EntityFrameworkLegacy.
I have a web application created using Entity Framework. The site was originally created using SQL Server CE, but I have since moved everything over to SQL Server. When I switched to SQL Server, I removed all references to SQL Server CE from my project, however when I try to add a new migration I am getting this error:
Schema specified is not valid.
Errors: (0,0) : error 0152: No Entity Framework provider found for the ADO.NET provider with invariant name 'System.Data.SqlServerCe.4.0'. Make sure the provider is registered in the 'entityFramework' section of the application config file.
I've discovered that if I create a new database and point my development system there everything works, but when I then point it back to one of my existing customers databases I get the error. It seems that the reference to SqlServerCe.4.0 is somehow embedded in the _MigrationHistory table.
Is it possible to manually rebuild _MigrationHistory for my existing databases? Or is there a better solution?
I'm getting the following error while trying to access the Worklight server deployed in my machine:
Error 500: Worklight Console initialization failed.Logged Exception:
java.lang.RuntimeException: FWLSE0206E: The project /worklight failed to initialize, because the project database schema for data source jdbc:db2://xxxxx:50000/WRKLGHT is from version N/A, which is not supported by the server from version 6.1.0.00.20131126-0630. Use the Worklight ant tasks to upgrade the project database schema. [project worklight]
Follow what the error message suggests.
Make sure that the database schema you use for your DB2 database is one that fits Worklight 6.1

I have installed AppFabric onto Server2012. I checked the prerequisites were installed first and have installed accumulative update 3. I have an instance of SQL Server 2012 installed to SP1 and the OS indicates that all updates have been installed.
When viewing the dashboard I am receiving the error:
Unable to cast object to type
'System.Management.Automation.PSCustomObject' to type
'Microsoft.ApplicationServer.Management.Data.Group...'
I've found minimal information during my google searches, none of which are providing a solution to the problem.
Can anyone help with this?
I had the same issue and found that applying Windows Update KB2932678 (Cumulative update package 5 for Microsoft AppFabric 1.1 for Windows Server) stopped the error from coming up.
EDIT : KB3092423 (Cumulative Update 7) is the latest one I could find, so if you are going to apply an update you might as well apply the latest one.
I've had the same issue. I read somewhere (don't have the link) that it appears because there are no records in the AppFabric Monitoring DB's table that contains the instances (of the service).
Once you have at least one record there, the error will disappear and the Dashboard will show the WF instances correctly.
This worked in my case.
UPDATE:
To be precise, the table which is relevant for the AppFabric Dashboard to stop showing the aforementioned error is: AppFabric Persistence DB's table [System.Activities.DurableInstancing].[InstancesTable] . This table should contain at least one record that is related to the WF Service(s) that the current AppFabric Dashboard is shown for.
