When I double click on a ViewPage or a ViewUserControl in Visual Studio 2008 the whole application hangs for me, I have no idea why...
The only error log I can find in the Event Log is this:
.NET Runtime version 2.0.50727.3053 - Fatal Execution Engine Error (7A035E00) (80131506)
For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
Googling the hex error (7A035E00) and/or the version number 2.0.50727.3063 brings up some promising results.
The most likely fix appears to be to reinstall the .NET framework.

Make sure you are using the latest version of the .NET framework. The 2.0 version is available at Microsoft .NET Framework Version 2.0 Redistributable Package (x86), and the 3.5 version is available at Download Microsoft .NET Framework 3.5

I have Visual Studio 2019 updated to the latest current version of 16.18.4 (see screenshot), the .NET 5.0 is installed (see screenshot made in visual studio installer) and yet when creating new projects or then changing
target framework, the .NET 5.0 framework is not available. In the about box Visual Studio displayed .NET 4.8, not .NET 5.0.
To help anyone else who might face a moment of confusion as I did, the following allows creating a .NET Framework Windows Forms project
while the following allows targeting either .NET Core 3.1 or the newer .NET 5.0
and, as said, you can't simply set from VS a .NET Framework project to target the new .NET 5.0.
I just installed the .Net Core 3.0 SDK (both 64 and 32 bit version) and yet, the .Net Standard 2.1 Targeting Pack is not shown in Visual Studio's list. It is going up until 2.0 only. What am I doing wrong?
Apologizing. The problem is that I had to update visual studio.
Interestingly enough, I had Visual Studio open for several hours, and even though an update existed, it didn't prompt me to update, leaving me with the impression that it was already in the most recent version.
I had to run Visual Studio Installer manually to request for an update
After installing Update 4 for VS 2013, I immediately started getting the message
This project is incompatible with the current version of Visual Studio
when I try to open all my MVC projects.
I've tried following advice on older posts, such as changing the version of visual studio, and checking for other updates, but none have worked.
I am using Visual Studio Premium 2013 and have .Net 4.5. It happens to projects that target both 4.0 and 4.5.
This is happening with MVC projects, but it does not happen when opening a simple project containing only .cs files.
Repairing Visual Studio turned out to be the solution.
I believe the initial update was unsuccessful because the C drive was low on space. Clearing up space, and repairing both .Net 4.5.1 and Visual Studio did the trick.
I have attempted to create an MVC 5 project by creating an MVC 4 project in Visual Studio 2012 and installing MVC 5 through Nuget.
I can build this fine.
I attempt to add a reference to another DLL, Sitecore.Mvc.DLL, which I can see was built against MVC 5.1.0. The DLL reference is added fine, and there seems to be no .NET framework conflict (which is where I've seen this issue in the past).
I'm trying to add a using statement to my code:-
using Sitecore.Mvc.Presentation;
IntelliSense picks this up fine....even allowing me to auto-complete 'Presentation'.
However when I build I get the following error:-
The type or namespace name 'Sitecore' could not be found (are you missing a using directive or an assembly reference?)
What could be the issue here?
I'm using:-
Visual Studio 2012 - Update 4
MVC 4 Web Application (initially)
MVC 5.1.0 Nuget Package
Sitecore 7.2 - Update 2 (where Sitecore.Mvc.DLL comes from)
.NET 4.5.2 installed on my machine.
Turns out I'm using a different version of Sitecore.Mvc.DLL, which IS targeted to .NET 4.5.1. Seems like the mscorelib reference in Reflector doesn't quite tell all the details.
Now I need to target my Web App to .NET 4.5.1, which means I need to follow the steps here to be able to select it.

Thanks, and sorry to #Khanh TO, and everyone else for helping out.
I downloaded Spark 1.1 release from http://sparkviewengine.codeplex.com/releases/view/27601 and cannot find the msi package for Visual Studio integration promised in docs.
Can anyone explain why?
For VS2008 support, I'm not sure why it's not included in the latest downloads on codeplex, but you can still get the .msi from the download on spark downloads page.
For VS2010, the answer is a little bit more complicated. The short version though is that the visual studio editor changed drastically in VS2010 and the way the old plug-in was providing intellisence is no longer appropriate.
I was able to get the msi installed and working from 1.0.39935.0 with 1.1. I had to close and re-open VS and a few pages.
