Upgrading to .NET 5

After upgarding the TargetFramework of the solution to net5.0 and upgrading the Microsoft.VisualStudio.Web.CodeGeneration.Design reference to 5.0.0, you may get the following errors when building the solution:

Version conflict detected for Microsoft.CodeAnalysis.CSharp.Workspaces. Install/reference Microsoft.CodeAnalysis.CSharp.Workspaces 3.7.0 directly to project MyProject to resolve this issue.

Version conflict detected for Microsoft.CodeAnalysis.Common. Install/reference Microsoft.CodeAnalysis.Common 3.7.0 directly to project MyProject to resolve this issue.

Telerik.UI.for.AspNet.Core depends on version 3.3.1 or a higher version of the following packages:

<PackageReference Include="Microsoft.CodeAnalysis" Version="3.3.1" />
<PackageReference Include="Microsoft.CodeAnalysis.CSharp" Version="3.3.1" />

However, automatic dependencies resolution is not achieved by updating the Microsoft.VisualStudio.Web.CodeGeneration.Design reference to 5.0.0 and trying to restore packages.

Solution

Install the all-in-one NuGet package Microsoft.CodeAnalysis version 3.7.0 or higher and build the solution.
