Support using Blazor to build .NET tools #47576

Open danroth27 opened 1 year ago

danroth27 commented 1 year ago

You can create .NET tools that can be installed and used from the .NET CLI. It would be useful if you could build a UI for a .NET tool using Blazor. It looks like this used to be possible at some point but then a change to static web assets made the scenario more difficult: https://github.com/dotnet/sdk/issues/28881. This issue tracks improving the user experience and making this a supported scenario with proper guidance.

Thanks @danroth27 for picking this issue back up! I think this is a really neat way to use Blazor.

If an example of this is interesting for your development, I am currently using the workaround I mentioned in dotnet/sdk#28881 in AttackSurfaceAnalyzer: https://github.com/microsoft/AttackSurfaceAnalyzer/blob/8f3ee6911ae19650e0dc433aecddef60d7cca151/Cli/AttackSurfaceAnalyzerClient.cs#L435-L471.

We use this to provide a simple cross platform GUI in our published nuget: dotnet tool install -g Microsoft.CST.AttackSurfaceAnalyzer.CLI

You can launch the GUI with: asa gui

As for how this could be better supported. Maybe it is possible as part of the build to inject the expected relative staticwebassets path with respect to the unpacked tool binary to some value that can be accessed with reflection?

Background

Prior to .NET 6 the wwwroot was included in nupkg alongside the binaries, so when running an unpacked .net tool this would transparently work using the assets from wwwroot adjacent to the binaries. For an example, see attack surface analyzer 2.2.78 nupkg which was built with .NET 5. In .NET 5 it appears wwwroot was also packed to the staticwebassets folder at the root of the nupkg.

Starting in .NET 6, wwwroot is no longer packed alongside the binaries in the nupkg and appears to only be included once in the staticwebassets folder (for an example with both .NET 6 and .NET 7 binaries see asa 2.3.297).
