    <p>I have a solution that contains a number of different projects that include both WinForms and WebApi (RC). I am seeing an issue with WebApi tests hanging when a prior test instantiates a class that derives from <code>System.Windows.Forms.Form</code>. You can find a sample solution that demonstrates the problem here: <a href="https://dl.dropbox.com/u/3688049/SampleSolutions/TestSolution.zip" rel="nofollow">https://dl.dropbox.com/u/3688049/SampleSolutions/TestSolution.zip</a></p> <p>The solution has NuGet package restore enabled so all the dependencies should get pulled down upon build.</p> <p>If the <code>var form = new Form1();</code> call in Class1.cs is not commented out, then the tests will hang (using latest nuget version of nunit). If it is commented out, the tests pass.</p> <p>Any help would be greatly appreciated.</p> <p><strong>Class1.cs</strong></p> <pre class="lang-cs prettyprint-override"><code>[TestFixture] public class Class1 { [Test] public void AaaWindowsFormsApp() { // If this line is not commented out the BbbTestWebApiApp test will hang. var form = new Form1(); } [Test] public void BbbTestWebApiApp() { var config = new HttpConfiguration(); var server = new HttpServer(config, new MyMessageHandler()); var client = new HttpClient(server); var request = new HttpRequestMessage(HttpMethod.Get, "http://localhost/"); var response = client.SendAsync(request).Result; Assert.AreEqual(HttpStatusCode.OK, response.StatusCode); } } </code></pre> <p><strong>MyMessageHandler.cs</strong></p> <pre class="lang-cs prettyprint-override"><code>public class MyMessageHandler: DelegatingHandler { protected override Task&lt;HttpResponseMessage&gt; SendAsync(HttpRequestMessage request, CancellationToken cancellationToken) { return Task.Factory.StartNew(() =&gt; request.CreateResponse(HttpStatusCode.OK)); } } </code></pre> <p><strong>UPDATE</strong></p> <p>It seems that adding the <code>RequiresSTA</code> attribute to the <code>System.Windows.Forms.Form</code> tests resolves the issue. </p> <p>I'm not sure why adding the WebApi in-memory hosting exposed the problem though.</p> <p><strong>UPDATE 2</strong></p> <p><code>RequiresSTA</code> only seems to help if you are running the tests via the GUI. The console runner still seems to hang.</p>

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.
