  1. Solution

  • ABP 9.x targets .NET 9. The official migration guide states that if you plan to use ABP 9.0, you need to migrate your solutions to .NET 9.0. Therefore, ABP 9.0/9.1 packages (for example, Volo.Saas.Host.Application 9.0.0) are not compatible with net8.0 and will produce NU1202 (exactly like in your screenshot), because those packages include net9.0 TFMs.

  • What you can do:

    • Option A (stay on .NET 8): Keep your solution on ABP 8.x (latest 8.3.4) which fully supports .NET 8.
    • Option B (move to ABP 9.x): Upgrade your solution to .NET 9 (update TargetFramework to net9.0 and update Microsoft.* packages to 9.0.0) and then update ABP to 9.x.

  • Minimal steps for Option B (upgrade to .NET 9 + ABP 9.x):

    1. Install .NET 9 SDK.
    2. Change all project <TargetFramework> to net9.0 (and update global.json if present).
    3. Upgrade Microsoft.* NuGet packages to 9.0.0.
    4. abp update (to move ABP packages to 9.x).
    5. Apply the ABP 9 migration adjustments (e.g., MapAbpStaticAssets if applicable), as per the guide.

  • Why your error happens:

    • The package Volo.Saas.Host.Application 9.0.0 only provides net9.0; your project targets net8.0. NuGet raises NU1202: “not compatible with net8.0”.
