C A problem that countless masters can t solve

If there is an exception or a null reference, it must be a problem with the program itself.

It is recommended to compile in debug mode and copy it along with the pdb file to see which line is wrong**.

Or use remote debugging to check, the new version of VMware supports remote debugging, and I'm not sure if other virtual machines support it.

ps。Try to calm your attitude and mood when asking questions, after all, everyone is willing to solve the problem for you, and there is no obligation, so it is not appropriate to lose your temper with others if you can't solve it.

There are some things in the virtual machine.,There's also a limit.,After all, it's virtual.,You can use it in a normal fantasy world!!

Haven't encountered this before.

Is it a Silverlight program?

Silverlight needs to be installed.

1.There may be something incompatible, lack of support for composition, or a change in the version of the system function being executed.

2.It may be that the operating system is not compatible, and if you compile on a 2008 system, it is estimated that the chances of it will be able to execute will increase.

Or if it doesn't work, you'll find the reason in the compiler.

3.The program is broken, make a new copy and try it (I used to have this problem occasionally).

Look**, problem signature 09, null reference exception, missing dll or something missing?

You can install a vs environment debugging in the virtual machine, if you don't want to install it, search the Internet carefully:.NET program.

If you want to be a programmer, you can't be impatient, and depending on your tone, you are not suitable to be a programmer at this stage.

Is yours a win7 system?

The project I did with VS2005 in my XP system also had this problem in Win7. It didn't work out either.

I don't think this is an issue with the framework version. It's a problem with the virtual machines themselves. Since it just runs on a virtual machine, there must be something in the program that the virtual machine will not support.

The higher version of the framework is compatible with the lower version, so there is compatibility.

Remove some features and try to regenerate them. Or try more with different settings on the publishing method, and check the problem step by step.
