Clear Workload Cache<\/h3>\n<p>Clear the workload cache to remove potentially corrupted or conflicting workloads:<br \/>\n<code>dotnet workload clean<\/code><\/p>\n<h3>2. Uninstall Workloads<\/h3>\n<p>Uninstall all workloads to reset the installed workloads:<br \/>\n<code>dotnet workload uninstall --all<\/code><\/p>\n<h3>3. Repair .NET SDK Installation<\/h3>\n<p>Repair the .NET SDK installation by re-running the installer from the <a href=\"https:\/\/dotnet.microsoft.com\/download\/dotnet\/7.0\" target=\"_blank\" rel=\"noopener\">official .NET download page<\/a>.<\/p>\n<h3>4. Install Required Workloads<\/h3>\n<p>Reinstall only the required workloads for your application:<br \/>\n<code>dotnet workload install wasm-tools<\/code><\/p>\n<h3>5. Verify Installation<\/h3>\n<p>Verify that the correct workloads are installed:<br \/>\n<code>dotnet workload list<\/code><\/p>\n<h3>6. Restart IDE<\/h3>\n<p>Restart Visual Studio 2022 or JetBrains Rider to ensure that the new workload configurations are applied.<\/p>\n<h2>Additional Troubleshooting<\/h2>\n<ul>\n<li>Check if the environment variable DOTNET_CLI_HOME is set correctly.<\/li>\n<li>Ensure that no custom global.json file is forcing the use of an incompatible SDK version.<\/li>\n<li>Update Visual Studio 2022 to the latest version, as it may include patches for SDK compatibility.<\/li>\n<\/ul>\n<h2>Conclusion<\/h2>\n<p>By following the steps outlined, the SDK resolver failure due to conflicting workloads between .NET 6 and .NET 7 should be resolved. <\/p>\n<div class=\"qanda-read-box\"><div class=\"bg-light read-more-icon\"><img decoding=\"async\" src=\"https:\/\/assets.bacancytechnology.com\/qanda\/wp-content\/uploads\/2025\/04\/24061434\/read-txt.png\" alt=\"Also Read\"><p><\/p><h3>Also Read:<\/h3><a href=\"https:\/\/www.bacancytechnology.com\/blog\/entity-framework-core-in-net-6\" target=\"_blank\">Entity Framework Core in .NET 6<\/a><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Issue Overview After installing the .NET 7.0.100 SDK, existing .NET applications built with .NET 6 or .NET 7 fail to load in Visual Studio 2022 or JetBrains Rider.
