Hands On Lab: Introduction to Windows Workflow Foundation (WF4)

Thanks for the great tutorial!  Unfortunately I've run into an issue and I can't move past it with the existing code sample as it's written...

In Exercise 6, Task 1 you introduce the use of TextContext in the ShouldRunActivityOnBackgroundThread method.  When I put that code into my test class, Visual Studio underlines WriteLine in red and the error is "Cannot access non-static method "WriteLine" in static context."  If I try to build I get this exception for each of the two lines it's on:

An object reference is required for the non-static field, method, or property 'Microsoft.VisualStudio.TestTools.UnitTesting.TestContext.WriteLine(string, params object[])'	C:\Projects\HelloWorkflow1\HelloWorkflow.Tests\SayHelloTest.cs	64	13	HelloWorkflow.Tests

I've tried Googling the proper way of calling this, but every example I find gives me the same syntax.  Not sure what I'm missing here, but the only way I can move past it is to change it to Console.WriteLine.  Any idea how I can fix this?

Thanks!

I had the same issue initially - you need to flesh out your own TestContext for that unit test. The easiest way to do that may be to just selected the test project in the solution, go to the "Test" menu at the top, select "New Test", and finally choose the "Unit Test" template. It will create the outline code for your TestContext in the new test file, which you can then paste in to your existing unit test file.

I have the same problem. The fix you suggested did not change anything.

adding this to class seems to work, or at least it lets the solution compile.  Now, to find what this writes to.
private TestContext _testContext;

        public TestContext TestContext
        {
            get { return _testContext; }
            set { _testContext = value; }
        }
 got this from:

This bit of code (above) is missing from the included code/guidance. If you watch the video very closely for Exercise 6 about 3m30s in you will see it flash by.

I am getting build errors 1 & 2 both are same subsequent code in SayHelloTest.cs/ShouldRunActivityOnBackgroundThread.  I copied the code, so dont know what could have gone wrong...

            TestContext.WriteLine("Test thread is {0}", Thread.CurrentThread.ManagedThreadId);
            TestContext.WriteLine("Activity thread is {0}", activityThread);

Error	1	An object reference is required for the non-static field, method, or property 'Microsoft.VisualStudio.TestTools.UnitTesting.TestContext.WriteLine(string, params object[])'	C:\myData\SandBox\HelloWorkflow1\HelloWorkflow.Tests\SayHelloTest.cs	37	13	HelloWorkflow.Tests

Anyone know whats wrong?

Thanks,

solution below by Christopher Hines fixed it for me.  I guess should have looked at the threads...

I get the following error, any ideas on how to resolve it?

ICAP Error (icap_error) 
 
An error occurred while performing an ICAP operation: Internal error: 79 An unexpected error occurred.  
There could be a network problem, the ICAP service may be misconfigured, or the ICAP server may have reported an error.  

Thanks,

Dont know what was different, but i was able to download later and it worked...

I have tried a couple times to install the labs but I get an error. The log file tells me that the path is too long. This path apparently seems to points to the folder where installer extracts files. I don't know how to change the path or fix the error. Please help.
Thanks.

Sorry you are experiencing trouble with this.  I'm not sure how to help except to say that we have similar content in the Visual Studio 2010 training kit (Introduction to Workflow lab).  In that kit the delivery mechanism is different so you won't have this problem.  You can either download the kit or do the online version at http://msdn.microsoft.com/en-us/VS2010TrainingCourse_IntroToWF

It appears there is a conflict with the nice descriptive folder names and limitations of the system.IO objects in .Net.  
Install Error : System.IO.PathTooLongException: C:\Documents and Settings\[myName]\Local Settings\Application Data\Microsoft\VisualStudio\10.0\Extensions\Microsoft\Lab - Intro To WF4\1.0\Templates\Projects\Workflow\Hands On Lab\Exercises\LabComplete.zip: HelloWorkflow.Tests/HelloWorkflow.Tests.vstemplate

I also have the ZIP file version, but it is not clear where the files should be extracted to.

The installation fails with a path too long error on Windows XP.  Works fine on Windows 7.

When I follow myour steps the file is downloaded but all i get is the error message "The file is not a valid VSIX package". Any suggestions?

I'm having the same problem, and the reason being the download stops at 10.3mb. While the total size is 10.8mb.
