About incompatibility between Microsoft. NET Beta1 and Visual Studio. NET Alpha

[Happy!] At 11:56:22, add it to Joy ASP Forum:

Note: if anyone can download VS. NET beta1, please let me know and deliver a free book. Thank you! Joy@china.com)

Symptom: If you have installed ngws sdk Preview before and installed Visual Stuio on this basis.. NET Alpha version, if you install Microsoft. NET worker processes, generally up to 95%. At the same time. NET has been basically lost, as long as a debugging, it will tell you that "the System cannot find the specified file" error, at the same time, you cannot connect to some of the most basic assembly System. data, and the system reports an error.
Solution:
A. About MDM. ExE
MDM.exe is. NET, the full name of a service program is Mache Debug Manage, which is described as "Manage Local and Remote Visual Stuio Debug ", you can find it in the management tool service of the control panel. You can try to close it, but the system reports an error and cannot close it, the only solution is to set it to disabled first, and then restart the machine. This is all OK.
B. How to uninstall VS. NET
Maybe you try to use the Add/delete program or the original installer to uninstall the program, but it takes only a few seconds for the program to report that you have deleted the program, but when you look for it, the program is still there, and it seems that the program cannot be deleted. Well, come with me. This is a magic weapon that I found out after an hour of exploration.
Open the Start menu and enter the following sentence in the run: Running msiexec.exe/x {33334F07-0C6B-11D3-A51D-00A0C9231BA1} NOVSUI = 1 ". Then press enter and the system will automatically delete it for you. When I was writing this article, the system was being deleted.
C. Where does Config. WEB go?
Config. the WEB is no longer installed under the complus package in the win2000 installation path as before, but a new path is found, that is, [win2000path] microsoft. netframework [version. name] below, the win2000path is the path for you to install win2000, for example, my C: winnt, Version. name is a string with the V header. The current version number.
You can configure your Config. web here
D. Constant Null
VB and C # Always use Null to represent Null values, but they are no longer used in beta1. DBNull is used to represent them. This is one of the several errors in the program of bean curd's cross-site webpage reading. In addition, I feel that the readline () method is not good. Instead, I should change it to Readtoend (), after reading all the data at a time, you don't have to judge where it is. In addition, the encoding problems involved in the bean curd article are incorrect. If you use its program to read a Chinese webpage, all the results are garbled, whether or not you have corrected Config. WEB. In fact, you only need to change the ASCII in the program to Default and use the Default code of the webpage. It's easy, right?
