I am working with a solution that contains an ASP.NET project and a class library project. It works great for years. In the past few months, I upgraded it from VS 2005 and .NET 2.0 to VS 2008 and .NET 3.5.
During the update process, I did not notice any problems, and it works fine.
After clicking on the production and leaving it alone, I finally returned to make some changes. However, when I try to open it in VS 2008, it will work. VS opens and acts as if everything is in order, but when loaded, the VS window simply disappears.
The application event log shows this:
.NET Runtime version 2.0.50727.3607 - Machine Failure Error (7A036050) (80131506)
I did some research that pointed to a possible corrupt .NET installation. This made no sense to me, since all my other VS 2008 applications (6 more) opened and worked perfectly in VS 2008. But, since I could not come up with a different solution, I decided to install the latest updates for .NET. 2.x and 3.x, found here .
After installing the updates, it worked fine.
Just a few weeks later, I ran into the same problem. I tried to run the same .NET updates to find out if this fixes the problem, but there are no dice.
I took the solution to the problem in the next step and launched WinDbg against VS, opening the solution. Here is what I got:
CLR: (C:\WINDOWS\\GAC_MSIL\System.Web.Extensions\3.5.0.0__31bf3856ad364e35\System.Web.Extensions.dll) , C:\WINDOWS\\GAC_MSIL\System.Core\3.5.0.0__b77a5c561934e089\System.Core.dll
, , , . System.Web.Extensions 3.5 .
