* Add workflow to perform automated checks for PRs * Downgrade Microsoft.CodeAnalysis to 4.4.0 This is a workaround to fix issues with dotnet-format. See: - https://github.com/dotnet/format/issues/1805 - https://github.com/dotnet/format/issues/1800 * Adjust editorconfig to be more compatible with Ryujinx code-style * Adjust .editorconfig line endings to match .gitattributes * Disable 'prefer switch expression' rule * Remove naming styles These are the default rules, so we don't need to override them. * Silence IDE0060 in .editorconfig * Slightly adjust .editorconfig * Add lost workflow changes * Move .editorconfig comment to the top * .editorconfig: private static readonly fields should be _lowerCamelCase * .editorconfig: Remove alignment for declarations as well * editorconfig: Add rule for local constants * Disable CA1822 for HLE services * Disable CA1822 for ViewModels Bindings won't work with static members, but this issue is silently ignored. * Run dotnet format for the whole solution * Check result code of SDL_GetDisplayBounds * Fix dotnet format style issues * Add missing trailing commas * Update Microsoft.CodeAnalysis.CSharp to 4.6.0 Skipping 4.5.0 since it breaks dotnet format * Restore old default naming rules for dotnet format * Add naming rule exception for CPU tests * checks: Include all files before excluding paths * Fix dotnet format issues * Check dotnet format version * checks: Run dotnet format with severity info again * checks: Disable naming style rules until they won't crash the process anymore * Remove unread private member * checks: Attempt to run analyzers 3 times before giving up * checks: Enable naming style rules again with the new retry logic
