Title: SQLiteFactory throws AppDomainUnloadedException when I execute a VS2010-unit test twice
Status: Closed Type: Code_Defect
Severity: Critical Priority: Immediate
Subsystem: None Resolution: Fixed
Last Modified: 2011-09-30 09:00:18
Version Found In:
using VS2010 1. Create a TestProject 2. Create an EntityFramework model with one entity 3. Create a unit test: [TestClass] public class UnitTest1 { [TestMethod] public void TestMethod1() { var conStr = ConfigurationManager.ConnectionStrings["StorageEntities"].ConnectionString; doTest(conStr); }
private static void doTest(string conStr) { using (var storage = new StorageEntities(conStr)) { storage.ExecuteStoreCommand("SELECT * FROM [SystemInfo]"); } } } 4. add app.config: <> <DbProviderFactories> <remove invariant="System.Data.SQLite"/> <add name="SQLite Data Provider" invariant="System.Data.SQLite" description=".Net Framework Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite"/> </DbProviderFactories> </>
<connectionStrings> <add name="StorageEntities" connectionString="metadata=res://*/Model.csdl|res://*/Model.ssdl|res://*/Model.msl;provider=System.Data.SQLite;provider connection string="data source=_full_path_to_database_file_;BinaryGUID=False"" providerName="System.Data.EntityClient"/> </connectionStrings>

5. Create a new connection in Server Explorer, create a database-file and create table inside it via Query window: CREATE TABLE IF NOT EXISTS [SystemInfo] ( [MajorVersion] integer NOT NULL , [MinorVersion] integer NOT NULL , PRIMARY KEY ([MajorVersion], [MinorVersion]));

6. Run the unittest. It'll pass 7. Run the unittest one more time. It'll fail with the following exception: Test method SQLiteAppDomainUnloadException.UnitTest1.TestMethod1 threw exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.TypeInitializationException: The type initializer for 'System.Data.SQLite.SQLiteFactory' threw an exception. ---> System.AppDomainUnloadedException: Attempted to access an unloaded AppDomain.


On evetything works fine. Please fix ASAP. Thanks
