Visual Studio Extensibility: Configure Custom Tool in an ItemTemplate

Last week I created a Visual Studio custom tool to encrypt configuration files(more information about the process here and here). To simplify the usage and improve the discoverability I also created a custom Item Template.

But how can I automatically set this custom tool when a new item is created?
  • Open the .vstemplate-file.
  • Add a WizardExtension-node to the XML file:
<VSTemplate Version="3.0.0" xmlns="http://schemas.microsoft.com/developer/vstemplate/2005" Type="Item">
<TemplateData>
<DefaultName>Encrypted Config.encryptedconfig</DefaultName>
<Name>Encrypted Config</Name>
<Description>Encrypted Config</Description>
<ProjectType>CSharp</ProjectType>
<SortOrder>10</SortOrder>
<Icon>__TemplateIcon.ico</Icon>
</TemplateData>
<WizardExtension>
<Assembly>Microsoft.VSDesigner, Version=10.0.0.0, Culture=Neutral, PublicKeyToken=b03f5f7f11d50a3a</Assembly>
<FullClassName>Microsoft.VSDesigner.ProjectWizard.ItemPropertyWizard</FullClassName>
</WizardExtension>
<TemplateContent>
<References />
<ProjectItem SubType="" TargetFileName="$fileinputname$.encryptedconfig" ReplaceParameters="false">test.encryptedconfig</ProjectItem>
<ProjectItem SubType="" TargetFileName="$fileinputname$.config" ReplaceParameters="true">test.config</ProjectItem>
</TemplateContent>
</VSTemplate>
  • Afterwars specify a CustomTool attribute on the ProjectItem:
<VSTemplate Version="3.0.0" xmlns="http://schemas.microsoft.com/developer/vstemplate/2005" Type="Item">
<TemplateData>
<DefaultName>app.encryptedconfig</DefaultName>
<Name>Encrypted Config</Name>
<Description>Encrypted Config</Description>
<ProjectType>CSharp</ProjectType>
<SortOrder>10</SortOrder>
<Icon>__TemplateIcon.ico</Icon>
</TemplateData>
<WizardExtension>
<Assembly>Microsoft.VSDesigner, Version=10.0.0.0, Culture=Neutral, PublicKeyToken=b03f5f7f11d50a3a</Assembly>
<FullClassName>Microsoft.VSDesigner.ProjectWizard.ItemPropertyWizard</FullClassName>
</WizardExtension>
<TemplateContent>
<References />
<ProjectItem SubType="" TargetFileName="$fileinputname$.encryptedconfig" ReplaceParameters="false" CustomTool="EncryptedConfigGenerator">app.encryptedconfig</ProjectItem>
</TemplateContent>
</VSTemplate>

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...

.NET 9 - Goodbye sln!

Although the csproj file evolved and simplified a lot over time, the Visual Studio solution file (.sln) remained an ugly file format full of magic GUIDs. With the latest .NET 9 SDK(9.0.200), we finally got an alternative; a new XML-based solution file(.slnx) got introduced in preview. So say goodbye to this ugly sln file: And meet his better looking slnx brother instead: To use this feature we first have to enable it: Go to Tools -> Options -> Environment -> Preview Features Check the checkbox next to Use Solution File Persistence Model Now we can migrate an existing sln file to slnx using the following command: dotnet sln migrate AICalculator.sln .slnx file D:\Projects\Test\AICalculator\AICalculator.slnx generated. Or create a new Visual Studio solution using the slnx format: dotnet new sln --format slnx The template "Solution File" was created successfully. The new format is not yet recognized by VSCode but it does work in Jetbr...
