To deploy applications written with dotConnect for MySQL you should register run-time assemblies Devart.Data.MySql.dll and Devart.Data.dll at Global Assembly Cache (GAC) for appropriate framework or place them in the folder of your application (Bin folder for web projects). These two assemblies should be available in all applications written with dotConnect for MySQL. Make sure that your project contains the license resource as it is described in Licensing.
Another way to install the needed *.dll is to launch the dotConnect for MySQL setup program and choose "Minimal installation". Note that according to End-User License Agreement this is the only install you can do on target machine. You must not distribute any other part of dotConnect for MySQL.
Applications written with dotConnect for MySQL may not contain the license resource when they are deployed on the target machine where dotConnect for MySQL is installed with "Minimal" option.
When your code uses dotConnect for MySQL via a factory-based class, you should register configuration information in the DbProviderFactories section of the *.config file to inform your environment about the existence of the provider factory. The provider factory is described either in machine.config (globally), in app.config or in web.config (just for your application), but not in both files. This is done as follows:
<system.data> <DbProviderFactories> <remove invariant="Devart.Data.MySql" /> <add name="dotConnect for MySQL" invariant="Devart.Data.MySql" description="Devart dotConnect for MySQL" type="Devart.Data.MySql.MySqlProviderFactory, Devart.Data.MySql, Version=22.214.171.124, Culture=neutral, PublicKeyToken=09af7300eec23701" /> </DbProviderFactories> </system.data>
Replace 126.96.36.199 here with your actual version.
When deploying ASP.NET applications, the following additional assemblies may be needed:
- Devart.Data.MySql.Web.dll - in case if the MySqlDataSource component or ASP.NET providers are used;
- App_Licenses.dll - if the application is a non-precompiled web site.
When deploying ASP.NET applications using dotConnect for MySQL SimpleMembership providers, you need to deploy the Devart.Data.MySql.Web.dll assembly for .NET Framework 4, not the one for .NET Framework 2.0. It is located in the Web\ASP.NET 4 subdirectory of the dotConnect for MySQL installation directory (by default, from Program Files\Devart\dotConnect\MySQL\Web\ASP.NET 4) and has the revision number 4 in its version.
When deploying ASP.NET applications using ADO.NET implementation of ASP.NET Identity via dotConnect for MySQL, you need to deploy the Devart.Data.MySql.Web.Identity.dll assembly.
When deploying ASP.NET applications using Entity Framework implementation of ASP.NET Identity via dotConnect for MySQL, you need to deploy the Devart.Data.MySql.Entity.EF6.dll assembly. It is located in the Entity\EF6 subfolder of the dotConnect for MySQL installation folder.
The following permissions are required by dotConnect for MySQL as partially trusted code (this is actual for web projects):
- In Direct mode - medium trust plus SocketPermission.
- In client mode - just medium trust permissions. However, if there are no dotConnect for MySQL assemblies in GAC, the UnmanagedCode flag should be added to SecurityPermission section.
Since dotConnect for MySQL uses standard Microsoft .NET licensing licensing, it additionally requires RegistryPermission. And though SecurityPermission is granted by default when using medium trust level, the set of flags for the SecurityPermission must be extended. You need to add the following flags: Assertion, SkipVerification, UnmanagedCode, and SerializationFormatter.
For the information on how to do this see Configuring Trust Level for Web Applications.
Entity Framework and LightSwitch ProjectsWhen deploying Entity Framework (or LightSwitch) projects, it is necessary to:
First, you need to check if the Devart.Data.MySql.Entity.EF<Version>.dll assembly is available for your application. The <Version> here is the version of Entity Framework used in your application. For Entity Framework v1 the assembly is called Devart.Data.MySql.Entity.EF1.dll, for Entity Framework v4 it is Devart.Data.MySql.Entity.EF4.dll, for Entity Framework v5 or v6 it is Devart.Data.MySql.Entity.EF5.dll or Devart.Data.MySql.Entity.EF6.dll respectively. For Entity Framework Core it is Devart.Data.MySql.Entity.EFCore.dll. The assembly should reside in the application's folder or in GAC.
Please note that there are two versions of Devart.Data.MySql.Entity.EFCore.dll assemblies - for Entity Framework Core 1.1 and for Entity Framework Core 2.0. The first is located in the \Entity\EFCore subfolder of the dotConnect for MySQL installation folder, and the second one - in the \Entity\EFCore2 subfolder.
- If you use Code-First Migrations feature of Entity Framework v4 or Entity Framework v5, you also need to check if the Devart.Data.MySql.Entity.Migrations.EF<Version>.dll assembly is available for your application. For Entity Framework v6 this assembly is not needed.
- If you use Entity Framework Spatials and NetTopologySuite, you also need to check if the Devart.Data.MySql.Entity.Spatials.EF<Version>.dll assembly is available for your application.
- Inform your environment about the provider factory existence (add the entry to the DbProviderFactories section as it is described above).
You can find these assemblies in the Entity folder in the provider installation folder, in the subforder, corresponding to the Entity Framework version necessary.
If you are registering the provider in the machine.config file, please take into account the Entity Framework version. Entity Framework v1 - specific applications require an entry in the .NET Framework 2.0 configuration file, and Entity Framework v4 and later - specific applications should be registered in the .NET Framework 4.0 configuration file. For Entity Framework Core there is no need to register the provider in the machine.config file.
You can also read Microsoft's Deployment Considerations on ADO.NET Entity Framework.
Deploying LightSwitch applications is described here.
To deploy applications written with LinqConnect support in dotConnect for MySQL, besides deploying the general assemblies you should register run-time LinqConnect assemblies Devart.Data.MySql.Linq.dll and Devart.Data.Linq.dll at Global Assembly Cache (GAC) or place them in the folder of your application (the Bin folder for web projects).
Workflow Foundation Projects
To deploy applications using MySQL Workflow Instance Store or MySQL Workflow Tracking, in addition to the general assemblies, you also need to deploy the Devart.Data.MySql.WorkflowFoundation.dll assembly.
Sync Framework Projects
To deploy applications using Sync Framework, in addition to the general assemblies, you also need to deploy the Devart.Data.Synchronization.dll and Devart.Data.MySql.Synchronization.dll assemblies. Such application also require the Sync Framework itself installed.
