How to specify to not use .NET 4.7.2 in app.config

After installing the Visual Studio 2019 preview, and the required .NET framework 4.7.2, I found that another (.NET) application does not start anymore, and gives me an error:




The value specified in System.Windows.Markup.StaticExtension caused an exception




This application is not mine, so I can't change the source code.



Is there a way to specify in the application's config file to not use 4.7.2, but 4.5 instead? I changed the sku version in the supportedRuntime section from 4.5 to 4.5.1 and 4.5.3 (which are both installed), but that didn't change anything.



<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.3" />




My OS is Windows 10 Enterprise, release 1709.



Here's a screenshot showing the .NET installs I have:



.NET Framework installations



And



Microsoft optional components

  • I think the required .NET framework version is defined during compilation or in the source code. So I don't think you can change that for the executable only.

  • @SaaruLindestøkke If that were the case it wouldn't have been 4.7.2 in the first place.

  • @Ramhound Thanks, I added a screenshot, and Yes, I probably meant targeting packs ;-). I also found out that my problem might be caused by having both 4.7.1 and 4.7.2 installed: developercommunity.visualstudio.com/content/problem/307924/…. I'm currently trying to find out what's the best way to uninstall 4.7.1

  • @Ramhound Correct, that's exactly what I did. I now have 4.7.2, and I think I want to revert to 4.7.1. Uninstalling VS2019 didn't help here, and neither did running the 4.7.1 offline installer with the /repair or /uninstall option

There is no answer to my question, simply because it is not possible to have more than one 4.x version installed at the same time. Any .NET application that targets 4.x will run using the latest installed version.



Reverting to 4.7.1 is not intuitive, because the 4.7 versions do not appear in the Add/Remove programs section of Windows. What I did was:




  1. Uninstall VS 2019

  2. Start appwiz.cpl

  3. Select Display installed updates

  4. Uninstall KB4073120, which is the .NET Framework 4.7.2 for Windows 10:1709

  5. Reboot
