The people over at Microsoft have been working hard and have delivered a lot of stuff. That makes for a nice start after the holidays! So there’s a lot of cool stuff available to play with. I created some simple and easy to remember links for all of these goodies. Feel free to use and distribute these 🙂
We held a 2.5 hour presentation about .NET Core at the Betabit office in Rotterdam on March 29th. Where ‘we’ means my colleague Oscar van Tol and myself. We ended up having way too much content for the evening. We decided to host a hands-on workshop for those interested. At that workshop we will not only show .NET Core, but also enable you to have a go at it yourself. The location will most probably be the Betabit office in Utrecht because it’s located more central. Stay tuned for more info on the details of the workshop.
After making sure my Visual Studio always ran as an administrator by following my own post HowTo: Have Visual Studio always run as administrator on Windows 8, I got a message if I wanted to save changes to devenv.sln each and every time I double clicked a Solution. Since the problem kept occuring after installing Visual Studio 2015 CTP6, I wanted to solve it. So here we go!
Just a quick little post today: I got the error “The Path ‘path’ is already mapped in workspace ‘workspace’” when I connected to a new Team Foundation Server and tried to map my workspace today. I had connected to a Team Foundation Services project a while back to get some shared code, but I already removed the workspace and the server binding. Even though Visual Studio didn’t see any other bindings, mapping my workspace to the same folder the previous TFS binding was mapped to served me this error.
Just a quickie today: when working with Twitter Bootstrap tabs, like I am in my ASP.NET MVC 4 project, you might want to add Next and Previous buttons on the tabs to create something of a Wizard. Here’sa step by step overview of how I did this:
When debugging JavaScript in an ASP.NET MVC (4) application, it is not always enough to uncheck the ‘Disable script debugging’ checkboxes under ‘Tools’ – ‘Internet Options’ – ‘Advanced’ – ‘Browsing’. JavaScript inside a Razor view (a cshtml file) cannot be debugged from Visual Studio. To debug your JavaScript, move it to a separate .js file and link to that file from your Razor view. This way, breakpoints set in the JavaScript will be hit and you can debug from Visual Studio.
Problem:
Developing a generic class that maps datasets, datatables and datarows from a legacy system to my domain model, I ran into an issue. I wanted to call a generic method with a runtime type. Lets say the method looked like this: public string DoSomething<T>(string param). Because I use reflection to iterate properties on a type, the type of the properties was dynamic and only known at runtime. I wanted to do something like this:
Twitter Bootstrap is a… “Sleek, intuitive, and powerful front-end framework for faster and easier web development.” One of the nice things in Bootstrap is you can use icons from Glyphicons. To use these, you can simply use this markup <i class="icon-fire"></i> to get a nice fire icon.
In the past, when you had some XML document that you wanted to translate into classes we had to create / generate a schema based on the XML file. Next, we had to generate a class based on the schema with an external tool. Not all too user friendly and somewhat time consuming.
I opened a solution in Visual Studio 2012 on my laptop running Windows 8, when I was presented with the error “The Web Application Project SomeWebProject is configured to use IIS. Unable to access the IIS metabase. You do not have sufficient privilege to access IIS web sites on your machine.” The user I was logged in with was a local administrator and was able to open up and use IIS Manager, but still I was presented with this error. The solution to this is simple: start your Visual Studio with ‘Run as Administrator’. You can do this by right clicking the shortcut and selecting ‘Run as Administrator’.
Just a quick one: if you have a textbox with a Calendar (extender) from the Ajax Control Toolkit and an associated PopupButtonID which is an image, the calendar won’t close when you click outside the popup. Use an input type=”image”or an ImageButton to solve this problem.
When building an ASP application that generates Word documents, it was working fine on the local machine: A Windows XP installation with Office 2007. When we deployed it to windows 2008 (64 bit) and Word 2007 we saw that Documents.Open returned null. Other than this, there are no exceptions.
