Update .NET to 8.0

[mattleibow]

Description of Change

Updating .NET to the latest stable and prepare for .NET 9.0.

[benbaker76]

Please include an update to the install-dotnet-workloads.ps1 so it will build using the latest wasm-tools

It is there:

It is there:

When publishing for a Blazor Wasm (.NET 8.0) project it forced me to install wasm-tools-net6 or it would give me an error To build this project, the following workloads must be installed: wasm-tools-net6. To install these workloads, run the following command: dotnet workload restore.

I'm using Svg.Skia along with SkiaSharp.Views.Blazor. Without the latter I'd get System.DllNotFoundException: libSkiaSharp (previously I tried SkiaSharp.NativeAssets.WebAssembly instead but it didn't work).

What are you deploying? The wasm-tools-net6 is only used in net6, and I think nothing is using that in this repo after this PR?

My concern is that the script is specifically referring to wasm-tools-net6 rather than the latest (just wasm-tools) but you may be right in that it will use the latest once this PR is merged. I look forward to it and thanks for your work on the project.

Hi @mattleibow, do you plan to release a preview package that works on net9.0 + wasm?

With [email protected] I get:

System.DllNotFoundException: libSkiaSharp

When tweaking SkiaSharp.NativeAssets.WebAssembly.targets locally to include the native files I get a bit further but ends up with:

Unhandled exception rendering component: Could not set up parent class, due to: Could not load type of field 'SkiaSharp.Views.Blazor.Internal.JSModuleInterop:moduleTask' (0) due to: Could not resolve type with token 0100003b from typeref (expected class 'Microsoft.JSInterop.IJSUnmarshalledObjectReference' in assembly 'Microsoft.JSInterop, Version=6.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60') assembly:Microsoft.JSInterop, Version=6.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60 type:Microsoft.JSInterop.IJSUnmarshalledObjectReference member:(null) assembly:SkiaSharp.Views.Blazor.dll type:JSModuleInterop member:(null)

Please note that I'm trying in .NET 9 as I want to try out:

<WasmEnableThreads>true</WasmEnableThreads>

Which comes with its own set of issues 😅

Thank you!

Lets talk on this PR that I stopped as things were not actually implemented in .NET at the time: #2620
