CLR调试时的sos.dll/clr.dll/mscorwks.dll/mscordacwks.dll等动态库的版本对应

大家都知道,在调试托管代码时,一定会加载到sos/clr/mscorwks/mscordacwks这些动态库,才能够很好的完成我们的调试工作,那么他们的版本对应关系是怎样的呢,特别是clr.dll/mscorwks.dll有什么关系呢? clr是通用语言运行时库,对应的就是clr.dll/mscorwks.dll,在clr发展过程中,文件名发生了变化,他们的版本对应关系如下: .NET framework 版本 CLR 版本 CLR 文件名 1.1 1.1 mscorwks.dll 2.0 2.0 mscorwks.dll 3.0 2.0 mscorwks.dll 3.5 2.0 mscorwks.dll 4.0 4.0 clr.dll 4.5 4.0 clr.dll 我们在进行托管代码调试时,还会使用到sos.dll和mscordacwks.dll这两个动态库: SOS.dll SOS 调试扩展 (SOS.dll) 通过提供有关内部公共语言运行时 (CLR) 环境的信息,帮助你在 Visual Studio 和 Windows 调试器 (WinDbg.exe) 中调试托管程序。 mscordacwks.dll 这是进行调试的 数据访问组件 (DAC) 。SOS和CLR调试器使用 Data Access Component (DAC)来实现进程外调试

How to get Type of a column using DacFx api?

独自空忆成欢 提交于 2019-12-08 12:39:03
问题 In SSDT project, using DacFx API, I am querying in memory model of a database. I have been trying to retrieve Type of a column, but cannot figure it out. Any idea how this could be done? private void TestMethod() { using(TSqlModel model = new TSqlModel(SqlServerVersion.Sql110, new TSqlModelOptions {})) { string[] scripts = new[] { "CREATE TABLE t1 (c1 NVARCHAR(30) NOT NULL)", "CREATE TABLE t2 (c2 INT NOT NULL)" }; foreach (string script in scripts) { model.AddObjects(script); } var tables =

Is there any way to stop SqlPackage.exe setting default Filegroup in deployment script?

让人想犯罪 __ 提交于 2019-12-05 04:58:07
We are using Sql Server database projects to create deployment scripts from DacPac using SqlPackage.exe. We have different SQL Server Filegroups setup in various environments. When deploying we exclude Filegroups as we want objects to create in the default Filegroup. In database project settings the default Filegroup is not changed from PRIMARY. This presents a problem when attempting to deploy to an environment where the default Filegroup is not PRIMARY because the following code is included... ALTER DATABASE [$(DatabaseName)] MODIFY FILEGROUP [PRIMARY] DEFAULT; Is there a way to prevent this

DacFx DeploymentPlanExecutor OnExecute not called

点点圈 提交于 2019-12-04 04:59:37
问题 I'm trying to program a custom DeploymentPlanExecutor using Microsofts DacFx 3.0 but the OnExecute -Method is never called. If I use an identical DeploymentPlanModifier instead, OnExecute() is called as expected. No matter whether I add the Executor, the Modifier, or both, the DAC actually is successfully deployed to the Database. The Executor seems to be recognized during the Deployment since OnApplyDeploymentConfiguration() is called Unfortunately I wasn't able to find any examples that use

How to create/open DAC application in Visual Studio 2012?

梦想的初衷 提交于 2019-12-03 12:59:25
I am having a hard time figuring how to actually create or even open a DAC application with Visual Studio 2012. I am using SQL Server 2012. I have SSDT installed. Creating from Visual Studio: According to online documentation I should be able to see a project template with the name "Data Tier Application" but all I see is SQL Server Database Project. Are they the same? Creating from SSMS: In an online video the presenter is using SSMS -> Database -> Right Click -> Create Project menu item, and after the wizard a VS project is popped open. I do not have this menu item, what I have is Tasks ->

Android安全

Android主要有一下几个角度来提供保障性 1,Linux层各种安全机制,DAC、SELinux 2,所有的应用程序都强制运行在自己的sandbox 3,严格的进程间通信安全控制 4,应用程序签名 5,Permission机制 设备root 程序加固 程序注入 1,DAC(Discretionary Access Control)任意的、自主的, 客体的属主可以自主的决定是否将全部的或部分的访问权限授予其他主体,主体通常是指进程\线程、而客户则是文件、文件夹、TCP\IP、内存段、IO设备等各种资源 简单来说就是资源所有者可以决定是否把权限给其他主体 Linux中的UGO(User、Group、Others)就是一种表现形式,权限分为读、写、执行三种 2,MAC 是相对于DAC而言的。主体访问客体的权利取决于操作系统集体控制规则,而不是由主体自行决定的 3,基于MAC的SELinux SELinux是一个负责安全管理的Linux内核模块,他提供了完善的机制来支持访问控制 这两种模式DAC SELinux都存在于Android之中,检测权限会先经过DAC在检测SELinux Android系统安全保护 1,Permission机制 2,DAC(UGO)保护 3,SEAndroid Apk加固 1,防止二次打包(启动程序,获取当前签名,获取正确签名,判断二者是否相等) 2,防止反编译
