    Rubberduck

    Rubberduck

    Every programmer needs a rubberduck. COM add-in for the VBA & VB6 IDE

    Rubberduck aims to bring the VBIDE into this century. Rubberduck understands Classic-VB code like no other add-in, giving it superior static code analysis capabilities that go far above and beyond what is possible with simple text-based analysis. Avoid common pitfalls (some not-so-common) with dozens (100+) of configurable inspections. Gain full control over module and member attributes, create a virtual folder hierarchy, and document modules and procedures, all with special comment annotations. Navigate a Classic-VB project like never before, quickly locating identifier references, interface implementations, and anything else that has a name. Add a full folder structure for organizing your modules. Write code that runs your code and verifies its output is as expected, given controlled inputs. Organize tests into categories, run them directly in the VBIDE, and view results in a dedicated explorer toolwindow.

    Application Inspector

    Application Inspector

    A source code analyzer built for surfacing features of interest

    Microsoft Application Inspector is a software source code characterization tool that helps identify coding features of first or third party software components based on well-known library/API calls and is helpful in security and non-security use cases. It uses hundreds of rules and regex patterns to surface interesting characteristics of source code to aid in determining what the software is or what it does from what file operations it uses, encryption, shell operations, cloud API's, frameworks and more and has received industry attention as a new and valuable contribution to OSS on ZDNet, SecurityWeek, CSOOnline, Linux.com/news, HelpNetSecurity, Twitter and more and was first featured on Microsoft.com. Application Inspector is different from traditional static analysis tools in that it doesn't attempt to identify "good" or "bad" patterns; it simply reports what it finds against a set of over 400 rule patterns for feature detection including features that impact security.

    NSwag

    NSwag

    The Swagger/openAPI toolchain for .NET, ASP.NET Core and TypeScript

    NSwag is a Swagger/OpenAPI 2.0 and 3.0 toolchain for .NET, .NET Core, Web API, ASP.NET Core, TypeScript (jQuery, AngularJS, Angular 2+, Aurelia, KnockoutJS and more) and other platforms, written in C#. The OpenAPI/Swagger specification uses JSON and JSON Schema to describe a RESTful web API. The NSwag project provides tools to generate OpenAPI specifications from existing ASP.NET Web API controllers and client code from these OpenAPI specifications. The project combines the functionality of Swashbuckle (OpenAPI/Swagger generation) and AutoRest (client generation) in one toolchain (these two libs are not needed). This way a lot of incompatibilities can be avoided and features that are not well described by the OpenAPI specification or JSON Schema are better supported (e.g. inheritance, enum and reference handling). The NSwag project heavily uses NJsonSchema for .NET for JSON Schema handling and C#/TypeScript class/interface generation.

    Git Credential Manager

    Git Credential Manager

    Secure, cross-platform Git credential storage with authentication

    Git Credential Manager (GCM) is a secure Git credential helper built on .NET that runs on Windows, macOS, and Linux. It aims to provide a consistent and secure authentication experience, including multi-factor auth, to every major source control hosting service and platform. GCM supports (in alphabetical order) Azure DevOps, Azure DevOps Server (formerly Team Foundation Server), Bitbucket, GitHub, and GitLab. Compare to Git's built-in credential helpers (Windows: wincred, macOS: osxkeychain, Linux: gnome-keyring/libsecret), which provide single-factor authentication support for username/password only. GCM replaces both the .NET Framework-based Git Credential Manager for Windows and the Java-based Git Credential Manager for Mac and Linux. Git Credential Manager is currently available for Windows, macOS, and Linux*. GCM only works with HTTP(S) remotes; you can still use Git with SSH.

    Paket

    Paket

    A dependency manager for .NET with support for NuGet packages and Git

    A dependency manager for .NET with support for NuGet packages and Git repositories. NuGet does not separate out the concept of transitive dependencies. If you install a package into your project and that package has further dependencies then all transitive packages are included in the packages.config. There is no way to tell which packages are only transitive dependencies. Even more importantly: If two packages reference conflicting versions of a package, NuGet will silently take the latest version (read more). You have no control over this process. Paket on the other hand maintains this information on a consistent and stable basis within the paket.lock file in the solution root. This file, together with the paket.dependencies file enables you to determine exactly what's happening with your dependencies.
