如何方便地推断Azure SDK csrun.exe的路径？

Question

我遇到了一些 Azure 计算模拟器无法正确重新启动的问题。为了解决这个问题，我想在 Visual Studio 解决方案中的预构建步骤中添加 csrun /devfabric:stop 调用。

问题是 csrun.exe 位于我的计算机上的 C:\Program Files\Windows Azure SDK\v1.4\bin 中，并且该路径不在 %PATH% 上> 目录列表。我不想在我的解决方案中硬编码该路径。

有没有某种方法可以推断出路径，例如使用某些环境变量或类似的东西？

Answer 1

您可以按版本从注册表中读取 Azure SDK 路径。路径的最后一部分是版本...您的代码可以设置为版本，也可以迭代 v 键查找最新版本。我建议您为您支持的版本设置一个常量，并且当您将新的 SDK 作为先决条件时。

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SDKs\ServiceHosting\v1.4

这些路径下有一个“InstallPath”键。

我遇到了同样的问题，我生成了一个 PowerShell 脚本，该脚本使用 SDK bin 文件夹的路径设置环境变量。它会自动搜索注册表并找到最新安装的版本。它还可以回退到备用注册表位置，具体取决于您的脚本是在 32 位模式还是 64 位模式下运行。希望有帮助！

免责声明：在将脚本发布到此处之前，我从脚本中删除了一些内容，之后我没有对其进行测试，但我认为根据您的需要调试/调整它并不困难。

#the script attempts to perform the following:
#1. look for the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SDKs\ServiceHosting" registry key
#2. if the above key is present then read the child keys and retrieve the largest version number
#3. from the largest version number key retrieve the "InstallPath" string value to determine the path of the latest Azure SDK installation
#4. add an environment variable called "AzureSDKBin" (if not already added) with the path to the "bin" folder of the latest Azure SDK installation

#define the name of the config variable
$azureSDKPathVariable = 'AzureSDKBin'
$azureRegistryKey = 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SDKs\ServiceHosting'
$azureAlternateRegistryKey = 'HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Microsoft SDKs\ServiceHosting' #this is in case the PowerShell runs in 32bit mode on a 64bit machine
$azureMatchedKey = ''

#check if the environment variable was already defined
if ([environment]::GetEnvironmentVariable($azureSDKPathVariable,"User").Length -eq 0) {
    'Variable ' + $azureSDKPathVariable + ' is not defined, proceeding...'

    #try reading the registry key
    $keyExists = Get-Item -Path Registry::$azureRegistryKey -ErrorAction SilentlyContinue

    $azureMatchedKey = $azureRegistryKey #make a note that we found this registry key

    #stop if the key does not exist
    if ($keyExists.Length -eq 0) {
        'Could not find registry key in primary location: ' + $azureRegistryKey + ', attempting search in alternate location: ' + $azureAlternateRegistryKey

        #search the alternate location
        $keyExists = Get-Item -Path Registry::$azureAlternateRegistryKey -ErrorAction SilentlyContinue

        $azureMatchedKey = $azureAlternateRegistryKey #make a note that we found this registry key

        if ($keyExists.Length -eq 0) {
            'Could not find registry key for determining Azure SDK installation: ' + $azureAlternateRegistryKey
            'Script failed...'
            exit 1
        }
    }

    'Found Azure SDK registry key: ' + $azureMatchedKey

    #logic for determining the install path of the latest Azure installation
    #1. get all child keys of the matched key
    #2. filter only keys that start with "v" (e.g. "v2.2", "v2.3")
    #3. sort the results by the "PSChildName" property from which we removed the starting "v" (i.e. only the version number), descending so we get the latest on the first position
    #4. only keep the first object
    #5. read the value named "InstallPath" under this object
    $installPath = (Get-ChildItem -Path Registry::$azureMatchedKey | Where-Object { $_.PSChildName.StartsWith("v") } | sort @{expression={ $_.PSChildName.TrimStart("v") }} -descending | Select-Object -first 1| Get-ItemProperty -name InstallPath).InstallPath

    'Detected this Azure SDK installation path: "' + $installPath + '"'

    #set the variable with the "bin" folder
    [Environment]::SetEnvironmentVariable($azureSDKPathVariable, $installPath + 'bin\', "User")

    'Assigned the value "' + [environment]::GetEnvironmentVariable($azureSDKPathVariable,"User") + '" to environment variable "' + $azureSDKPathVariable + '"'
}
else {
    'Environment variable "' + $azureSDKPathVariable + '" is already defined and has a value of "' + [environment]::GetEnvironmentVariable($azureSDKPathVariable,"User") + '"'
}
