    <p>I am using EF4.3, ASP.NET MVC4, Microsoft.VisualStudio.TestTools.UnitTesting. </p> <p>Code works fine. I added Unit tests to test Controllers. The Unit tests fails with following exception : </p> <blockquote> <p>Access Violation Exception. Attempted to read or write protected memory. This is often an indication that other memory is corrupt.</p> <p>at ((IObjectContextAdapter)this).ObjectContext.MetadataWorkspace.LoadFromAssembly(typeof(MyBusinessEntity).Assembly);</p> </blockquote> <p>I have added [assembly: InternalsVisibleTo("TestProject")] to my Web project AssemblyInfo.cs</p> <p>Any suggestions ?</p> <p>Unit test code:</p> <pre><code> [TestMethod] public void GetEntity() { // Arrange MyControllercontroller = new MyController(); // Act var result = controller.GetEntity("737464305") as JsonResult; dynamic data = result.Data; // Assert Assert.IsNotNull(data); Assert.AreEqual("0", data.ProcessStatus); } </code></pre> <p>Controller action invokes a Stored Procedure using Entity Framework4.3 DBContext. The result of SP call is mapped to a Complex Type. The DBContext code for the SP call is :</p> <pre><code>public virtual ObjectResult&lt;MyEntity&gt; MYSP(string inparam) { ((IObjectContextAdapter)this).ObjectContext.MetadataWorkspace.LoadFromAssembly(typeof(MyEntity).Assembly); var inparamParameter = inparam != null ? new ObjectParameter("inparam", inparam) : new ObjectParameter("inparam", typeof(string)); return ((IObjectContextAdapter)this).ObjectContext.ExecuteFunction&lt;MyEntity&gt;("MYSP", inparamParameter ); } </code></pre> <p><strong>In general code works fine. However, Access Violation Error is thrown when Controller action is tested using Unit Test. in line ((IObjectContextAdapter)this).ObjectContext.MetadataWorkspace.LoadFromAssembly(typeof(MyEntity).Assembly);</strong></p>

    2. COThis may be a shot in the dark, but did you happen to rebuild the project or run the tests while still in debug mode or something? I believe I've seen similar problems in such cases..

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
