问题:
I am running Windows 2003 Enterprise SP2 running SQL 2005 Enterprise and am
getting repeated failures applying SQL 2005 SP2. The error is always the
same (see below).

I have made sure that there are no disabled services in the SQL Server
family of services, but this does not appear to have helped. This SQL
installation is pretty minimal, basically just the Database Engine. The
services list is:

SQL Server (MSSQLSERVER) Started Automatic Local System
SQL Server Active Directory Helper Manual (was disabled) Network Service
SQL Server Agent (MSSQLSERVER) Started Automatic Local System
SQL Server Browser Manual (was disabled) Local System
SQL Server FullText Search (MSSQLSERVER) Started Automatic Local System
SQL Server VSS Writer Started Automatic Local System

from the summary: ———————————————————————————-

**************************************************************************
解决方法:
From the error message “Error Description : MSP Error: 29528 The setup has
encountered an unexpected error while Setting Internal Properties. The
error is: Fatal error during installation”, this is a known issue. This
issue occurs because of one of the following reasons:

· An operation has removed the local groups for the initial installation of
SQL Server 2005.
· An operation has changed the security identifiers (SID) for the local
groups.

Considering your SQL Server is not a clustered instance, please follow the
below steps to workaround the problem:

Warning: Serious problems might occur if you modify the registry
incorrectly by using Registry Editor or by using another method. These
problems might require that you reinstall your operating system. Microsoft
cannot guarantee that these problems can be solved. Modify the registry at
your own risk.

1. Remove the following registry subkeys that store SID settings:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL.X\Setup\SQLGroup
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL.X\Setup\AGTGroup
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL.X\Setup\FTSGroup
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL.X\Setup\ASGroup

Note In these registry subkeys, MSSQL.X is a placeholder for the
corresponding value on a specific system. You can determine MSSQL.X on a
specific system by examining the value of the MSSQLSERVER registry entry
under the following registry subkey:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\Instance
Names\SQL\

2. Reinstall the SQL Server 2005 service pack or the SQL Server 2005 hotfix
package.

mscorsvw.exe is precompiling .NET assemblies in the background. Once it’s done, it will go away. Typically, after you install the .NET Redist, it will be done with the high priority assemblies in 5 to 10 minutes and then will wait until your computer is idle to process the low priority assemblies. Once it does that it will shutdown and you won’t see mscorsvw.exe. One important thing is that while you may see 100% CPU usage, the compilation happens in a process with low priority, so it tries not to steal the CPU for other stuff you are doing. Once everything is compiled, assemblies will now be able to share pages across different processes and warm start up will be typically much faster, so we’re not throwing away your cycles.

If you are really want to get rid of mscorsvw.exe from your task manager, just do:

ngen.exe executequeueditems

which will drain all the queued up work.

Long version

if you want a reference to an instance of a value type, the instance must be boxed. Usually this happens because you have a value type and you want to pass it to a method that requires a reference type.

Equals must be reflexive; that is, x.Equals(x) must return true.
Equals must be symmetric; that is, x.Equals(y) must return the same value as y.Equals(x).
Equals must be transitive; that is, if x.Equals(y) returns true and y.Equals(z) returns true, then x.Equals(z) must also return true.
Equals must be consistent. Provided that there are no changes in the two values being compared, Equals should consistently return true or false.

There are only three different ways to implement Equals.
Implementing Equals for a Reference Type Whose Base Classes Don’t Override Object’s Equals
Implementing Equals for a Reference Type When One or More of Its Base Classes Overrides Object’s Equals
Implementing Equals for a Value Type

Events typically use a delegate field to maintain the set of registered listeners.

The accessibility modifiers indicate which types and members can be legally referenced from code. The predefined attributes fine-tune this accessibility and allow you to change a member’s semantics.

When creating an instance of a reference type, memory is allocated for the instance,the object’s overhead fields (method table pointer and SyncBlockIndex) are initialized, and the type’s instance constructor is called to set the initial state of the object.

Type constructors shouldn’t call a base type’s type constructor. Such a call isn’t necessary because none of a type’s static fields are shared or inherited from its base type.

By default, the CLR assumes that all method parameters are passed by value. When reference type objects are passed, the reference (or pointer) to the object is passed (by value) to the method. This means that the method can modify the object and the caller will see the change. For value type instances, a copy of the instance is passed to the method.This means that the method gets its own private copy of the value type and the instance in the caller isn’t affected.

Strong Name Utility,SN.exe – [assembly:AssemblyKeyFile("fsyKey.keys")]

GAC – Global Assembly Cache C:\Windows\Assembly\GAC

GACUtil.exe

“(Version)_(Culture)_(PublicKeyToken)”

Response file :  on the command line prepended by an @ sign OR CSC.rsp OR /noconfig

Delayed Signing or partial signing. CSC.exe – AssemblyKeyAttribute and AssemblyDelaySignAttribute AL.exe /keyf[ile] or /delay[sign]

The following list summarizes the steps discussed in this section to develop your assembly

by using the delay signing technique:

1. While developing an assembly, obtain a file that contains only your company’s public key and add the following two attributes to your source code:

2. [assembly:AssemblyKeyFile("MyCompanyPublicKey.keys")]

[assembly:AssemblyDelaySign(true)]

3. After building the assembly, execute the following line so that you can install it in the GAC, build other assemblies that reference the assembly, and test the assembly.Note that you have to do this only once; it’s not necessary to perform this step each time you build your assembly.

SN.exe ÐVr MyAssembly.dll

4. When ready to package and deploy the assembly, obtain your company’s private key(key pair) and execute the following line:

SN.exe -R MyAssembly.dll MyCompany.keys

5. To test, turn verification back on by executing the following line:

SN -Vu MyAssembly.dll

Cultures are identified via a string that contains a primary and a secondary tag

RFC1766 zh-CN example: [assembly:AssemblyCulture("zh-CN")]

culture neutral

satellite assembly

Access a satellite assembly’s resources using the System.Resources.ResourceManager class.

using the System.Reflection.AssemblyCultureAttribute custom attribute instead of using AL.exe’s /culture switch

Privately deployed assembly

an application can control its directory and its subdirectories but has no control over other directories.

Use the classes defined in the System.Configuration namespace to manipulate a configuration file at runtime.

The Machine.config file is located in the following directory:
C:\WINDOWS\Microsoft.NET\Framework\version\CONFIG
