problem description
今早摸鱼的时候看见狼哥一个开源项目Dotnet9WPFControls，我非常感兴趣！结果 clone 下来之后，没跑起来？嗯？我姿势不对？好！我再跑！结果还是 run 不起来，无奈求教狼哥本人，狼哥亲自 clone 之后没在他的机器上重现我这个 bug。因为报错的这个库是 nuget 拉下来的，我们先看报错截图：

The third-party library is: "MaterialDesignThemes. Wpf"
The problem is already obvious. It is caused by the wrong version of the assembly due to library dependencies. We just need to find the PresentationFramework and find the corresponding version. The problem seems to be very clear.
Okay, let's follow the above ideas and start operating:
First query the storage location of the currently referenced PresentationFramework on the local machine:
So we enter this file directory:
There were no folders 6.0.2 and 6.0.16 at the beginning, but this was the one I downloaded later to solve this problem.
Then we clicked into the folder and found:
This PresentationFramework is the 6.0.0 version that reported the error. Therefore, according to our above solution ideas, we just need to replace this with the 6.0.2 version to solve the problem, right?
New questions arise
So I just did it, but a new question arises. Where can I find the 6.0.2 version of the Presentation Framework?
I observed several other similar DLLs of the PresentationFramework and found that this 6.0.0 is linked to the version of the. net sdk, which means that I can find the 6.0.2 version of the PresentationFramework by downloading the sdk of net6.0.2.
So I went to Microsoft's official website to download:
Please note that I have tested it and found that it is useless to download the desktop on the right to run. You must download the one on the left.
solve his
How do we replace the reference after downloading?
Simply enough, I came up with a very doggy but very convenient solution (because I just want to run the project and don't involve release, so I can do it, but if you need release, please be sure to prohibit it!)
That's right, it's just file renaming. After downloading version 6.0.2, our reference folder looks like this:
Let's change the prince with a raccoon cat!
Change 6.0.2 to 6.0.0:
Finally, restart the project, solve it perfectly and run it successfully:

Webmaster, this is also a new computer environment and it is running normally. Welcome to leave a message for discussion.
