I was at the AIC 2010 conference yesterday, which I enjoyed more than last year. The most interesting session was Ivar Jacobson. He discussed how immature our industry is, with its disjoint between software engineers and academic computer scientists. Something I have commented on before when discussing if our industry should be licensed. He discussed how we need to build our industry upon commonly agreed kernel of simple best practice activities, not upon some currently fashionable process whether it be Waterfall, CMMI, Agile, Lean etc. We must identify what are the best practices from all process (and all processes have something to offer) and teach them to students at University as this kernel of activities, as well as teaching how to compose them into more complex practices and hence whole development processes. Thus providing new entries to our industry with the base of reusable techniques that the can use for their whole career, irrespective of fashion. The key idea being that any current process model can be build by composing these kernel of basic activity. ...

In 2008 I wrote a post Running Fitnesse.NET tests using MSTest. Recently I had need to us this technique on a VS2010 project, and as is so often the issue the code that worked then does not seem to work now. All I can assume is that the Fitnesse API had altered, but I thought I was using the same assemblies! So I pulled down the code from http://sourceforge.net/projects/fitnessedotnet/ and had a poke about. Basically I seemed to be using the command line switches wrong. The listing below shows what I found is the working usage: ...

I my previous post I discussed how the DB label was not used for TPC Dbs in 2010. As I was working on a setup where a central SQL box was the DT for two virtualised TFS AT instances, I therefore needed to create my TPC databases manually if I wanted TPCs of the same name on each TFS instance. I won’t go over the [old post again](I had to create a TPC Dbs manually ), but in essence I was trying to create a TPC with the name ABC on a TFS instance with a database label of RC. So I tried to create the DB TFS_RC_ABC manually and pointed the TPC create process at this. It passed the verify but I then got a ...

When I said will our internet bits were back I was not quite right. I had forgotten that I had not re-pointed m own richardfennell domains to put to my blog. These are now done, so I hope all search results to my blog should resolve OK.

If your application has a dependency on an assembly built in .NET 2 you will see the error below if you try to run your application when it has been built in.NET 4. Mixed mode assembly is built against version ‘v2.0.50727’ of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information. This can be important in VS2010 testing, as test projects must be built as .NET 4, there is no option to build with an older runtime. I suffered this problem when trying to do some development where I hosted a webpart that make calls into SharePoint (that was faked out with Typemock Isolator) inside a ASP.NET 4.0 test harness ...

Found out something I did not know today, the TFS 2010 database label is only used for the server’s own primary configuration databases not for the DBs for the TPC it creates. For example on a 2010 RC install with the database label was set to RC during the installation. When I try to create a new TPC (called ABC) it tries to create a Db named TFS_ABC, even though the database label for TFS server can be seen to TFS_RC_ on the admin console and the instance’s primary databases are called TFS_RC_Configuration, TFS_RC_Warehouse and TFS_RC_Analysis. ...

My Team Build 2010 custom activity for Typemock Isolator is now available at http://site.typemock.com/add-ons/. It is packaged as a zip which include all the source and a compiled assembly as well a document detailing usage and why the solution is constructed as it is. Hope you find it useful

I recently tried to use Typemock Isolator inside a ASP.NET page load event, to fake out some SharePoint SPLists e.g. protected void Page_Load(object sender, EventArgs e) { SPSite fakeSite = Isolate.Fake.Instance(); …….. } This has worked in the past but using VS2010RC and Isolator 6.0.1.0 it failed. If running VS2010 as Admin I got the error “Could not load file or assembly ‘TypeMock, Version=0.12900.25133.13153, Culture=neutral, PublicKeyToken=37342d316331342d’ or one of its dependencies. The located assembly’s manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)”:“TypeMock, Version=0.12900.25133.13153, Culture=neutral, PublicKeyToken=37342d316331342d”}" If running as a non admin user I got the error “Attempted to read or write protected memory. This is often an indication that other memory is corrupt.” Typemock Support told me that I needed to edit the Typemock Isolator’s namespaces.dat file (in its programs directory), this is the file that lists valid test runners. I needed to add WebDev.WebServer40.exe to this file as this is program that makes the call to Isolator to do the faking. ...

Our new Internet line has now been commissioned fully and hopefully any problems you may have had accessing my blog via the blackmarble.com or co.uk domains should be over.

Whilst upgrading a single server instance of TFS 2010 Beta2 to the RC I got a TF254024 error. This occurred at the point in the upgrade wizard where it tries to list the databases available to upgrade. The reason for the error was the account I was logged in as (the domain administrator in my case) did not have rights on the SQL instance to see any TFS DBs. Once this was sorted, by granting owner rights to all the TFS DBs, all was OK. ...
