Visual Studio 2017 RC.3 26127.3 finally works ASP.Net Core correctly

At least in my experience. Even until this minor point release came out a few days after the more ‘major’ release, things did not work right.  Since there needed to be a more solid upgrade path from the project.json system to the ‘new’ MSBuild system, I was concerned about how much work it would take. In the end, not very much.  Bin and Obj folders needed to be deleted, and for some obscure reason, the EF 6.1.3 NuGet package needed to be added to the Asp.NET Core project (this wasn’t required previously, so I’m assuming this is just...

Be wary of Visual Studio 2017 RC

I made the mistake of installing this on multiple machines instead of my usual “install on one and check it out fairly thoroughly” routine.  I guess I had been lulled into somewhat of a sense of security with the beta/RC process for Visual Studio 2015, in that I didn’t think that installing 17 RC would break important parts of 15 functionality. To wit, simply installing 17 RC would break some .NET Core web apps inside Visual Studio 2015, even if I didn’t try to open/upgrade them in the new software. Various errors included: ...

Asp.NET Core + IIS + PEBKAC = WTF, Asp.NET Core + IIS – PEBKAC = Success

Thankfully, the issue, as it usually is, was with me. At some point, the publishOptions section of project.json switched from having an exclude section and put in an include section instead (which makes sense enough). Turns out if you don’t include, you know, all your content and views and whatnot, IIS doesn’t have anything to serve up. BTW, logging helps.  Duh. Once I figured out that it was serving static content (which a helpful doc tells you to do, which requires that you read the helpful doc), it became easy to track down. It does...

The new VisiCalc

Though I sometimes feel like it, I’m not actually old enough to know what VisiCalc was, but Joe Stagner wrote a post in which he made an analogy between the two: VisiCalc was THE spreadsheet of the day !  It might have done 2% of what Excel 2010 does, but when it was released it was an AMAZING innovation…ASP.NET/Web Forms was a perfect match for the skill set of the day (2001/2002) and was exactly what the industry needed at the time. I don’t know that I would say it was a *perfect* match, but I generally agree...

Alt.NET Baby-ism

So, Ayende wrote a post criticizing some API related stuff about the ASP.NET MVC Framework. Phil Haack had a reply that dealt with why the design was done the way it was done, which contained the following funny comment: “We spent a lot of time thinking about these design decisions and trade-offs, but it goes without saying that it will invite blanket criticisms. Fortunately, part of my job description is to have a thick skin. ;) In part, by favoring usability in this case, we’ve added a bit of friction for those who are just starting out...

Visual Studio 2008 - Vista SP 1: IIS 7 Debugging No Longer Works After SP Install

Now, to be clear, I believe that I am still working in classic mode and running VS 2008 as Administrator to get around all the issues that came up when Vista came out, so this may not apply to you. But, after installing SP1 for Vista, I could no longer debug my web applications running on IIS7.  I worried about some major problem that would take hours if not days to fix. As it turns out, the WAS service was not set to auto-start, which prevented any of the application pools from starting, which prevented the WWW service...

ASP.NET, DataContext, and LINQ to SQL: Business Process Model

In my previous post, I pointed out a good article by Rick Strahl on different ways to handle DataContext management and mentioned that I used his 'Business Object' method.  This actually isn't quite accurate, so let me expand on that a little bit. I'll use a standard e-Commerce site as an example.  If you think about most of the data access that is required when creating an eCom site, there is little about the DataContext that you really need to worry about.  Product lists, navigation elements, search results, and other items are essentially read-only, so you can use a...

LINQ to SQL DataContext and ASP.NET

I was about to write up a long post about this when I saw this post out today by Rick Strahl.  I'm using what he calls the 'Business Object' option, and I like it so far. His post is better, so read up.   Update: I'm actually using what I would call the Business Process option.  See here.

IIS 7, Vista, and Visual Studio 2005

A couple of points: - if you go into IIS 7 Manager, try to make changes like changing the default documents, and it gives you an “Access Denied” message, it means your web.config is read-only.  For some reason, every time you try to make changes, it apparently tries to open the web.config file (even if it doesn't do anything to it), and if it is read-only, it fails.  Even if you are running as administrator. - to debug, you have to run VS 2005 as administrator, you need to enable Windows Authentication, and you sometimes (not clear when exactly) need to run...

ASP.NET: Could not load type

Various solutions to this problem can be found here: http://forums.aspfree.com/net-development-11/parser-error-message-could-not-load-type-17894.html For me, deleting dlls usually works (you might also need to go into the temporary asp.net files directory inside the Microsoft.Net framework directory and delete all files there as well...this may require restarting or even rebooting the server).

Duplicate 'ComVisible' Attribute

This will happen within Visual Studio with Web Application Projects (the new project type from Microsoft..... http://msdn.microsoft.com/asp.net/reference/infrastructure/wap/default.aspx ) if you have nested web sites (e.g. you have a top-level site that has one or more child sites).  What happens is the project for the top-level site sees multiple assemblyinfo.cs files (its own and the child sites') when it tries to build, and so fails. Simply set the build action for the child sites' assemblyinfo.cs files to “None” (within properties), and all will be fine.  This is a project level setting, so the project for the child site will compile the asssemblyinfo.cs file normally.

Setup Web Admin Tool for Production Servers

From khaivq at http://forums.asp.net/1155428/ShowPost.aspx: “I have been able installed WebAdminTool for Production Servers using the following steps: Create a virtual directory ASP.NETWebAdminFiles in IIS that point to C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\ASP.NETWebAdminFiles Open properties windows of the new virtual directory, make sure that it is configured to run with ASP.NET 2.0, and in Security tab, uncheck Anonymous Access, check Integrated Windows Authentication. After that, you will be able to connect to WebAdminTools using the following syntax http://localhost/ASP.NETWebAdminFiles/default.aspx?applicationPhysicalPath=XXX&applicationUrl=/YYY in my case, it is: http://localhost/ASP.NETWebAdminFiles/default.aspx?applicationPhysicalPath=D:\Tasks\Libranyon\Photonyon\&applicationUrl=/Photonyon Although I don't recommend to do it, if you want to access WebAdminTool from other computer, open WebAdminPage.cs from (C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\ASP.NETWebAdminFiles\App_Code) and comment the following code block             if (!application.Context.Request.IsLocal) {                ...
